k3 series portable crushing plant-sbm industrial technology group
K3 Series Portable Crushing Plant adopts a new design concept. It uses modular vehicle design, able to be transported without disassembly. Besides, it boasts rapid installation and production, safety and environmental protection. Its launch will break the market pattern of portable and mobile crushers in the industry, and it is an ideal portable crushing plant in the domestic and foreign markets.
The coarse crushing module adopts the vibrating feeder of larger specifications, equipped with double-layer grate bars, with stronger feeding and pre-screening capacity, which can ensure the efficient and stable operation of the coarse crusher and effectively improve the overall processing capacity.
The equipment adopts a large capacity silo design, which can store more raw materials; the strengthened silo can also adapt to a variety of feeding methods such as loaders, excavators and conveyors, so as to ensure the continuous and stable feeding.
In order to better play the performance of portable crusher, high-quality supporting crushing and screening host is selected. The equipment has higher production efficiency, small installation size, compact structure and larger processing capacity. The productivity of mobile crusher is comparable to that of fixed plant.
The equipment can be transported by road without disassembly, and shipped by sea in containers. During production, no concrete foundation is needed. The portable crushing plant has hydraulic supporting legs which will be stretched out when arriving at the production site to quickly enter the operation mode.
In order to ensure the rapid installation and transportation, the on-board belt conveyor and electrical control system are adopted for the equipment, which can directly enter the feeding operation mode after being deployed on site.
In the design of the equipment, the modular and general design concept is adopted, and the mass production can be carried out according to the general module. The production quality is stable, the precision is high, and the stock cycle is short.
The equipment leaves installation space of tarpaulin, and the dust cover of material receiving and discharging can be configured to achieve the effect of dust reduction. Some special needs can also be satisfied by equipping the movable tarpaulin convertible to further reduce the dust emission and meet the requirements of strict environmental protection standards.
In the case that there are many fine materials after coarse crushing, the portable crusher for medium crushing can adopt the operation mode of screening fine materials in advance before crushing, which can effectively improve the overall production capacity. When the field operation has a long moving period, the tire chassis may not be selected, and a new semi mobile sled type plant is adopted to save the investment cost.
The portable crushing plant is usually powered by an external power source. The raw materials are uniformly sent to the jaw crusher or impact crusher by the vibrating feeder for coarse crushing. Next, the coarse crushed materials are sent to the cone crusher or impact crusher by the belt conveyor for further crushing. After that, the fine crushed materials are sent to the vibrating screen where materials meeting size requirement would be screened as finished products while unqualified ones sent back to the impact crusher or cone crusher for reprocessing, forming a closed circuit and multiple cycles. The granularity of finished products can be decided according to the needs of users.

iron ore mining business process & sap solution | sap blogs
Iron Ore Mining is one of the major Industry of Karnataka State in India. Bellary District alone in Karnataka houses about 60 Mines and produces over 40 million Tons of Iron Ore per annum. China was a major customerandof the 40 Million Tonnes Iron Ore produced in Bellary, 30 Million Tonnes was exported to China. In boom time Iron Ore was also called Black Gold and the Boom time began in early 2003 when China started gobbling up Iron Ore for 2008 Olympic Games. During this time the Iron Ore prices went up to 158$/Tonne and Mine Owners turned overnight billionaires.
Fortunately I got opportunities to visit two Iron Ore Mines and recentbeing Donimalai Mine in Bellary District couple of weeks back. I also had the opportunity to interact with few people working in the Mines. Iron Ore Mining Industry is a good case study for implementing SAP. There are not many examples of SAP implementation for Iron Ore Mining Industry in India.
Mining: It all begins with the Site Survey and Geological Benchmarking, where several rounds of Chemical Tests and QA Tests are performed to make sure the FE (FE is symbol of Iron) grade is above 60 % to make Mining commercially viable. Iron Ore produced for Export generally exceed 62% FE. Once the quality of the ore is assayed Drilling and Blasting is carried out followed by hauling the blasted ore to Crushers by Hydraulic Shovels and Large Dumpers.
Crushing and Screening:Here the large blocks of Iron Ore are Crushed into small lumps. Most of the times the size of the lumps are specified by the Customers. The Crushing may happen in several stages like Primary Crushing, Secondary Crushing and Tertiary Crushing. After each Crushing Process there is Screening Process to separate the Iron from Non-Iron Material and few Additives like Binding Agents and Cleaning Agents are mixed in the process. Large Conveyor Belts are used to move Crushed Iron Ore from Primary Crushing Plant to Secondary Plant and from Secondary Plant to Tertiary Plant and then to Screening Plants.
Loading:It is a visual treat to see several Conveyor belts moving Iron Ore Lumps from Crushing/Screening Plants to the Loading Plant. Loading Plant look similar to a large Crane with several control mechanisms to control loading. The Iron Ore is loaded into Railway Wagons or Large Trucks. Now the Iron Ore is ready to be delivered.Indian Iron Ore Mining Companies today suffer from fragmentation, disorderly competition and irregularly operation. This is resulting in declining quality of Iron Ore.
SAP Implementation should definitely help these Indian Mining Companies in terms of being better equipped to handle tougher competition as well as global recession.Refer to the below link for an old but interesting White Paper on what SAP Mining Solution can offer. http://www.sap.com/industries/mining/pdf/SAP_Mining_solution.pdf
Iron Ore Mining Industry Business processes can offer Implementation Challenges across all SAP Modules like Sales and Distribution, FI and CO, HR, Material Management, Production Planning, Quality Management, Plant Maintenance and EHS.
Sales and Distribution Regular Sale Order Process (with or without Contract) could be implemented. There would be export Sale Orders involving multiple currencies (USD or Euro etc) while all sales revenues would need to be accounted in local currencies (in this case INR). Inquiry Process, Quotation Process would also help.
Shipping and Transportation Planning would play a major role in Mining Industry, the costs involved in Shipping and Transportation is very critical in bagging orders. India Mining Industry today is suffering due to high Shipping and Transportation costs, Shipping fee of Sea Freight in particular is veryhigh(Reference Linkhttp://www.chinastakes.com/story.aspx?id=340).Both Road and Trainare used to transport Ore to the ports. Transportation by means of Road is very much evident today and this could be an EHS (Environment Health and Safety)risk that needs integration with SAP EHS Module.
SAP Transport Management (TM) can be implemented to plan transportation, track orders, calculate transportation charges and also help subcontracting and tendering transportation services. SAP TM can be integrated with SAP ERP Systems.
Production Planning All the Pre-Crushing processes can be mapped to one Plant (Mining Plant) and following by Crushing plants and Screening Plant and Loading Plant. The Production would happen in Batches and Batch Management with Batch Characteristics needs to be implemented.
Master Data like Material Master and BOM (one of two levels max) should be simple but there would be large number of Work Centers and relatively complex Routing with multiple operations. Standard Planning Strategies like Made-to-Order (20), Made-to-Stock (10) and Planning with Final Assembly (40) can be used. MRP would generate the Purchase Requests or Production orders or Subcontract Requests.
Regular Production Order Process integrated with Batch Management and Back flushing of components (Eg: Binders, Cleaning agents) can be implemented. Product Costing and Capacity Evaluation would also help.
Quality Management QM would require both Qualitative and Quantitative inspections here. Example for Qualitative inspection is FE % and example for Quantitative inspection is Iron Ore lump size. The inspection is performed for each Batch and necessary Quality Certificate is to be generated.
Material Management It would be interesting to handle Procurement of Explosives for Blasting Operation. Explosives Procurement is subjected tospecific Licensing/Governmentregulationsand severaldocuments along with Purchase Order are to be generated. Integration with SAP EHS module would be another key feature to handle.
Plant Maintenance Most interesting and most critical for this Industry would be Plant Maintenance Module. Since several Heavy Equipment like Hydraulic Shovels, Dumpers, Motors and Pumps etc are involved in every phase of Mining and Iron Ore processing. The breakdown is very common so both preventive and breakdown maintenance for all Equipments plays an important part. Both Mechanical and Electrical Maintenance would be evident.
EHS Environment and Health Safety is an important aspect for Mining Industry. Industrial Hygiene and Safety component of EHS Module can be implemented to define and manage Industrial Hygiene and Safety measures within the company. Creating risk assessments, recording and processing accidents/minor injuries, also generating Standard Operating Procedures and Accident Reports would be required.
In Mining Industry EHS would be integrated with most of the SAP Applications/Modules. Some key processes with requireEHS Integrations areShipping and Tranportation of Iron Ore, Procurement ofMaterials like Explosives etc, execution of Mining Orders (this involves Blasting Operations).

iron ore beneficiation processing,working principle of iron ore jaw crusher,iron ore machine for sale south africa | prominer (shanghai) mining technology co.,ltd
Iron ore is the main direction of iron. The quality of pure iron can be directly fed into the iron smelting furnace, and is related to the ore. The iron ore has a higher impurity content, and you need to process it before it can be put into production.
Iron ore beneficiation can be divided into three stages: crushing, grinding, and beneficiation. Reliable processing equipment can effectively reduce processing costs and improve economic benefits. Jaw crusher is a new type of iron ore crushing equipment. It is specially designed for the developed iron ore. It is stable in operation and has been widely used.
When working, iron ore enters the machine from the feed port, and the motor drives the big wheel throwing and eccentric shaft. The eccentric shaft is connected with the movable jaw. The claw will follow the eccentric shaft around a fixed jaw fixed on the crusher to make irregular movement and movement. The jaw and the fixed jaw are sometimes close, sometimes far. Close, squeeze and shear the iron ore, and generate a moving speed toward the discharge outlet; away from the iron ore, a vacant state, and under the action of gravity, the discharge, qualified materials, and unqualified materials are returned to the cavity and continue to break .

pebble semi-mobile crushing plant with low budget - hongxing machinery
Pebble semi-mobile crushing and screening equipment is widely used in crushing coal, ore, rock and other bulk materials in mines (coal mines, non-coal mines), metallurgy, highway,expressway, railway, mineral processing, hydropower engineering, building materials,municipal solid waste, chemical, and other fields.ThisChina HXJQsemi-portable crusher is suitable for a high-capacity secondary application or pebbleportable crushing application.
Semi-mobile crushing and screening equipment is divided into three forms: fixedcrusher, semi-mobile (sleigh)crusher, and full mobilecrusher. Semi-mobile crushing machineis composed of jawrockcrusher, impact rockcrusher, hydraulic conecrusher, roller crusher, vibrating feeder, vibrating screen, vertical shaft impact crusher, sand shaping machine, belt conveyor and so on.
The screening mobile crushing station is currently the same as other mobile crushing stations. It can be divided into standard version, closed-circuit type, click combination, and two-stage combination of crushing series. Screening mobile crushing station can provide complete equipment for the tire (semi-trailer) mobile crushing station. Besides, it has great flexibility, and it is more effective from rough to fine breaking, and the mobile jaw crusher, impact crusher, cone crusher, and vibrating screening equipment can be tailored.
There are also several types of crawler mobile crushing stations, which are mainly divided into crawler-type smashing crushing stations, crawler impact crushing stations, with and without screening, open and closed circuits, which will mainly be based on our standards. Tracked mobile crushing plants are divided into four categories: cone crushing crawler mobile crushing station, broken crawler mobile crushing station, counter-crawling crawler mobile crushing station, screening crawler moving crushing station.
The design conceptof the pebble semi-mobile crushingis mainly made according tothe customer, mainly to eliminate the broken site, environment, complicated foundation installation and so on. The integrated unit device and flexible mobile performance solve the crushing obstacles and save time and effort.
HXJQ company has many years of semi-mobile crushing station design, production, manufacturing experience, the production of various types of semi-mobile crushing station crushing capacity of 100-22000 t / h, the scope of supply involves a number of well-known mines, chemical and iron and steel enterprises at home and abroad.
After many years of practice, our company has gradually optimized and upgraded the structure of the semi-mobile crushing plants, and now the modular design technology of the main structure of the semi-mobile crushing station has been more mature. The semi-mobile crushing station designed and produced by our company is simple in structure, stable in operation, reliable in performance, convenient in installation, operation, and maintenance. The semi-mobile crushing station with a crushing capacity above 6000t/h has become one of the star products of Hongxing Machinery.
On July 10, 2018, a foreign customer was looking for semi-mobile screening machine (low cost and budget) with an output range 15-300TPH, semi-mobile jaw crusher, feed capacity of 500 ton per hour, feed size of 150*150mm, hopper capacity of 8 cubics.
HXJQ employee asked what kind of stone he needed to process, and he said the materials can be the pebble, granite, quartz, concrete, bluestone, iron ore, limestone, coal. After more than half a month of land transportation and shipping, the semi-mobile crushing station designed and produced by Hongxing Heavy Industry successfully landed in the Philippines. This set of equipment includes jaw mobile crushing station.
The technical engineer of HXJQ Heavy Industry, who have explained the product description and practical operation training to the foreign customer immediately after the acceptance and delivery of the crushing equipment. Now the semi-mobile crushing machine has been put into use, the operation is normal and the discharge granularity is uniform. In a word, what we have done makes the Philippine customer very satisfied.
The semi-mobile crushing plants are flowable rock crushing operation. Portable rock crusher can be regarded as a combination of fixed and movable crushers. It is important equipment for semi-continuous mining of large open pit mines and ideal equipment for crushing construction waste. This article mainly introduces the four-module components and design points of the semi-mobile crushing station for your reference.
The control tower module mainly includes the control tower steel structure main body and the control room, the steel grille, the walkway, etc.And the control room is placed on the control dischargingtape module.
After the plan is set, consider the tape machine belt to the crusher. If the center of the crusher to the belt machine is too high, the impact of the free fall of the material will be too large and the tape will be damaged; the small height will cause the material to suddenly increase and block the discharge port, which in turn will not break the material.
The processing capacity of the crusher will be affected by the conveying capacity of the feeder. For example, the processing capacity of the crusher is 450 m3/h, and the conveying capacity of the feeder cannot reach 450 m3/h, which will affect the processing capacity of the crushing station.
In the selection of the plate feeder, the size of the feed size should also be considered, because the width of the different plate feeders is limited, and it is slightly larger than the feed size to operate normally, otherwise it will be stuck in the front of the hopper. Unload the material into the crusher cavity and crush it.
The crushing capacityof pebble semi-portable crusher plants is also related to the volume of the hopper. If the hopper volume is too small, the feeder will quickly unload the material into the crusher cavity, and the hopper has no remaining material. If the truck cannot replenish the material in time, there will be No-load time. This will affect the processing capacity of the crushing station, and the truck will be limited.
Speaking of the tracked crusher, thecrawler jawmobile crushing stations independently developed by Zhengzhou HXJQ adopts a fully hydraulically driven crawler-type vehicle chassis. The equipment is not only beautiful in appearance, but also has high performance and high productivity.

iron ore processing,crushing,grinding plant machine desgin&for sale | prominer (shanghai) mining technology co.,ltd
After crushing, grinding, magnetic separation, flotation, and gravity separation, etc., iron is gradually selected from the natural iron ore. The beneficiation process should be as efficient and simple as possible, such as the development of energy-saving equipment, and the best possible results with the most suitable process. In the iron ore beneficiation factory, the equipment investment, production cost, power consumption and steel consumption of crushing and grinding operations often account for the largest proportion. Therefore, the calculation and selection of crushing and grinding equipment and the quality of operation management are to a large extent determine the economic benefits of the beneficiation factory.
There are many types of iron ore, but mainly magnetite (Fe3O4) and hematite (Fe2O3) are used for iron production because magnetite and hematite have higher content of iron and easy to be upgraded to high grade for steel factories.
Due to the deformation of the geological properties, there would be some changes of the characteristics of the raw ore and sometimes magnetite, hematite, limonite as well as other types iron ore and veins are in symbiosis form. So mineralogy study on the forms, characteristics as well as liberation size are necessary before getting into the study of beneficiation technology.
1. Magnetite ore stage grinding-magnetic separation process
The stage grinding-magnetic separation process mainly utilizes the characteristics of magnetite that can be enriched under coarse grinding conditions, and at the same time, it can discharge the characteristics of single gangue, reducing the amount of grinding in the next stage.
In the process of continuous development and improvement, the process adopts high-efficiency magnetic separation equipment to achieve energy saving and consumption reduction. At present, almost all magnetic separation plants in China use a large-diameter (medium 1 050 mm, medium 1 200 mm, medium 1 500 mm, etc.) permanent magnet magnetic separator to carry out the stage tailing removing process after one stage grinding. The characteristic of permanent magnet large-diameter magnetic separator is that it can effectively separate 3~0mm or 6~0mm, or even 10-0mm coarse-grained magnetite ore, and the yield of removed tails is generally 30.00%~50.00%. The grade is below 8.00%, which creates good conditions for the magnetic separation plant to save energy and increase production.
2.Magnetic separation-fine screen process
Gangue conjoined bodies such as magnetite and quartz can be enriched when the particle size and magnetic properties reach a certain range. However, it is easy to form a coarse concatenated mixture in the iron concentrate, which reduces the grade of the iron concentrate. This kind of concentrate is sieved by a fine sieve with corresponding sieve holes, and high-quality iron concentrate can be obtained under the sieve.
There are two methods for gravity separation of hematite. One is coarse-grained gravity separation. The geological grade of the ore deposit is relatively high (about 50%), but the ore body is thinner or has more interlayers. The waste rock is mixed in during mining to dilute the ore. For this kind of ore, only crushing and no-grinding can be used so coarse-grained tailings are discarded through re-election to recover the geological grade.
The other one is fine-grain gravity separation, which mostly deals with the hematite with finer grain size and high magnetic content. After crushing, the ore is ground to separate the mineral monomers, and the fine-grained high-grade concentrate is obtained by gravity separation. However, since most of the weak magnetic iron ore concentrates with strong magnetic separation are not high in grade, and the unit processing capacity of the gravity separation process is relatively low, the combined process of strong magnetic separation and gravity separation is often used, that is, the strong magnetic separation process is used to discard a large amount of unqualified tailings, and then use the gravity separation process to further process the strong magnetic concentrate to improve the concentrate grade.
Due to the complexity, large-scale mixed iron ore and hematite ore adopt stage grinding or continuous grinding, coarse subdivision separation, gravity separation-weak magnetic separation-high gradient magnetic separation-anion reverse flotation process. The characteristics of such process are as follows:
(1) Coarse subdivision separation: For the coarse part, use gravity separation to take out most of the coarse-grained iron concentrate after a stage of grinding. The SLon type high gradient medium magnetic machine removes part of the tailings; the fine part uses the SLon type high gradient strong magnetic separator to further remove the tailings and mud to create good operating conditions for reverse flotation. Due to the superior performance of the SLon-type high-gradient magnetic separator, a higher recovery rate in the whole process is ensured, and the reverse flotation guarantees a higher fine-grained concentrate grade.
(2) A reasonable process for narrow-level selection is realized. In the process of mineral separation, the degree of separation of minerals is not only related to the characteristics of the mineral itself, but also to the specific surface area of the mineral particles. This effect is more prominent in the flotation process. Because in the flotation process, the minimum value of the force between the flotation agent and the mineral and the agent and the bubble is related to the specific surface area of the mineral, and the ratio of the agent to the mineral action area. This makes the factors double affecting the floatability of minerals easily causing minerals with a large specific surface area and relatively difficult to float and minerals with a small specific surface area and relatively easy to float have relatively consistent floatability, and sometimes the former has even better floatability. The realization of the narrow-level beneficiation process can prevent the occurrence of the above-mentioned phenomenon that easily leads to the chaos of the flotation process to a large extent, and improve the beneficiation efficiency.
(3) The combined application of high-gradient strong magnetic separation and anion reverse flotation process achieves the best combination of processes. At present, the weak magnetic iron ore beneficiation plants in China all adopt high-gradient strong magnetic separation-anion reverse flotation process in their technological process. This combination is particularly effective in the beneficiation of weak magnetic iron ore. For high-gradient strong magnetic separation, the effect of improving the grade of concentrate is not obvious. However, it is very effective to rely on high-gradient and strong magnetic separation to provide ideal raw materials for reverse flotation. At the same time, anion reverse flotation is affected by its own process characteristics and is particularly effective for the separation of fine-grained and relatively high-grade materials. The advantages of high-gradient strong magnetic separation and anion reverse flotation technology complement each other, and realize the delicate combination of the beneficiation process.
The key technology innovation of the integrated dry grinding and magnetic separation system is to "replace ball mill grinding with HPGR grinding", and the target is to reduce the cost of ball mill grinding and wet magnetic separation.
HPGRs orhigh-pressure grinding rollshave made broad advances into mining industries. The technology is now widely viewed as a primary milling alternative, and there are several large installations commissioned in recent years. After these developments, anHPGRsbased circuit configuration would often be the base case for certain ore types, such as very hard, abrasive ores.
The wear on a rolls surface is a function of the ores abrasivity. Increasing roll speed or pressure increases wear with a given material. Studs allowing the formation of an autogenous wear layer, edge blocks, and cheek plates. Development in these areas continues, with examples including profiling of stud hardness to minimize the bathtub effect (wear of the center of the rolls more rapidly than the outer areas), low-profile edge blocks for installation on worn tires, and improvements in both design and wear materials for cheek plates.
With Strip Surface, HPGRs improve observed downstream comminution efficiency. This is attributable to both increased fines generation, but also due to what appears to be weakening of the ore which many researchers attribute to micro-cracking.
As we tested , the average yield of 3mm-0 and 0.15mm-0 size fraction with Strip Surface was 78.3% and 46.2%, comparatively, the average yield of 3mm-0 and 0.3mm-0 with studs surface was 58.36% and 21.7%.
These intelligently engineered units are ideal for classifying coarser cuts ranging from 50 to 200 mesh. The feed material is dropped into the top of the classifier. It falls into a continuous feed curtain in front of the vanes, passing through low velocity air entering the side of the unit. The air flow direction is changed by the vanes from horizontal to angularly upward, resulting in separation and classification of the particulate. Coarse particles dropps directly to the product and fine particles are efficiently discharged through a valve beneath the unit. The micro fines are conveyed by air to a fabric filter for final recovery.
Air Magnetic Separation Cluster is a special equipment developed for dry magnetic separation of fine size (-3mm) and micro fine size(-0.1mm) magnetite. The air magnetic separation system can be combined according to the characteristic of magnetic minerals to achieve effective recovery of magnetite.
After rough grinding, adopt appropriate separation method, discard part of tailings and sort out part of qualified concentrate, and re-grind and re-separate the middling, is called stage grinding and stage separation process.
According to the characteristics of the raw ore, the use of stage grinding and stage separation technology is an effective measure for energy conservation in iron ore concentrators. At the coarser one-stage grinding fineness, high-efficiency beneficiation equipment is used to advance the tailings, which greatly reduces the processing volume of the second-stage grinding.
If the crystal grain size is relatively coarse, the stage grinding, stage magnetic separation-fine sieve self-circulation process is adopted. Generally, the product on the fine sieve is given to the second stage grinding and re-grinding. The process flow is relatively simple.
If the crystal grain size is too fine, the process of stage grinding, stage magnetic separation and fine sieve regrind is adopted. This process is the third stage of grinding and fine grinding after the products on the first and second stages of fine sieve are concentrated and magnetically separated. Then it is processed by magnetic separation and fine sieve, the process is relatively complicated.
At present, the operation of magnetic separation (including weak magnetic separation and strong magnetic separation) is one of the effective means of throwing tails in advance; anion reverse flotation and cation reverse flotation are one of the effective means to improve the grade of iron ore.
In particular, in the process of beneficiation, both of them basically take the selected feed minerals containing less gangue minerals as the sorting object, and both use the biggest difference in mineral selectivity, which makes the two in the whole process both play a good role in the process.
