gold ore crushing process and gold crusher

gold ore crushing process and gold crusher

Gold ore is one of the world's leading precious metal ores. It not only plays an important role in the industry and in life, but also the reserveof it is an important basis for maintaining financial stability. Therefore, gold ore mining and beneficiation have great significance. Generally speaking, in the gold ore beneficiation process, crushing is the first step and it influences the following steps greatly.

Gold ore production process includes crushing, grinding, beneficiation three processes. Currently,the gold ore processing methods are as follows: First of all, send the large gold ore to jaw crusher evenly and continuously for primary crushing by vibrating feeder. And then, transport the crushed gold ore to cone crusher for secondary crushing. Then, we need to use a vibrating screen to separate the gold ore into different sizes. The part which meets the requirement will be send to ball mill for grinding, while the rest part which doesnt meet the requirement will be returned to cone crusher for re-crushing. After grinded by ball mill, the gold powder need to be transported to the flotation machines or other beneficiation equipment to separate the gold concentrate from tailings. At last, send the gold concentrate to dryer, and you will get pure gold powder.

Crushing is an important part of gold beneficiation processes, andit direct impacts on the processing efficiency of the next steps. Generally, traditional gold crushing equipment includes jaw crusher, impact crusher, cone crusher, and so on.

After many years of research on gold crushing and gold beneficiation process technology, SBMs experienced engineers developed a series of gold ore crusher, and designed professional gold beneficiation process. Our perfect gold ore crusher includes many different types, such as gold ore jaw crusher, gold ore impact crusher, and gold ore cone crusher.

Jaw crusher is the most common gold ore mining crushing equipment. Jaw crusher crushing ratio can reach 4-6. Therefore, jaw crusher is widely used for crushing all kinds of large size and high hardness materials. Jaw crusher simulates the movement of animals two jaws. Movable jaw does periodic reciprocating motion, and sometimes separately from the fixed jaw plate, sometimes close. When these two jawsseparate, the materialsget into the crushing chamber for breaking and the finished products discharge from the spout. When these two jaws close, the materials squeezed by the two jaws, and all of them broken at finally.

Cone crusher is suitable for gold medium and fine crushing operations. Our gold ore cone crusher absorbed world advanced crushing technology and it has reached the advanced level. After optimized, the yield significantly improved.And the product shape is also greatly improved. The structure of it is obviously different from traditional ones. But it combines all the advantages of each type cone crusher. It is quite suitable for fine crushing and superfine crushing hard materials like gold ore.

large production conglomerate crushing processing line

Conglomerate is a kind of rock whose particle debris content is more than 30%. At the same time, the diameter of particle debris is larger than 2 mm. Conglomerates main constituent is lithic debris, only a small amount of mineral debris. And the interstitial materials are sand, silt, clay and chemical substances sediment. The hardness of conglomerate is 7, the proportion is 2.65.The colors are always milky white, yellow, brown, and gray. Conglomerate has a higher fire resistance. According to the size of gravel, conglomerate can be divided into boulder conglomerate (> 256 mm), large conglomerate (64 to 256 mm), pebbles conglomerate (4 to 64 mm) and fine conglomerate (2 to 4 mm). Depending on the complexity of gravel ingredients, conglomerate can be divided into single-component conglomerate and complex-component conglomerate.

At first, we need to choose a primary crusher. Jaw crusher is always the necessary equipment in various minerals processing line.It is with the features of large capacity, high reliability, easy maintenance and low operating cost. So it is widely applied in coarse crushing of a variety of high hardness materials and low hardness materials.

After primary crushing, we need a cone crusher for secondary crushing. You have many different choices, such as CS Cone Crusher, HCS Cone Crusher, HPC Cone Crusher, and PY Cone Crusher. All of them are designed by our professional engineers. Our cone crushers absorb advanced technology around the world, and adopt high-tech materials.

soybean oil production line, soybean oil extraction plant project

soybean oil production line, soybean oil extraction plant project

The soybean oil production line is the process of treating soya bean with the press method or leaching method to obtain more crude oil and then refined to obtain edible refined oil. Pressed soybean oil has natural colors, aromas and flavors, and retains raw materials various nutritious ingredients when comparing with the leached oil. The physical pressing line requires raw materials to be carefully selected, and the soya bean is pre-treated through cleaning, crushing, softening, rolling and extruding. After that, the cleaned beans are added during the pressing process and the oil is extracted from the pressing machine, and the finished oil is produced by using high-tech physical refining filtration purification technology. The physical pressing method maintains the original flavor of soybeans, rich in vitamin E, and has a long shelf life. And the screw pressed oil has no additives, no solvent residue, and no soap content. Soybean oil pressing line is a combination of modern and traditional technology that produces pure natural soybean oil.

Soybean should be cleaned first. The main purpose of this section is to remove the impurities of soybeans. The impurities are mainly plant impurities (such as bean stems, pods, etc.), metal impurities and non-metallic impurities.

Generally, soybeans are required to be broken into 4 to 8 valves, and the powdery degree (when crushed beans passing through 20 meshes screen) is less than 10%. The crusher is preferably a toothed roll crusher with cutting, impacting and bending effects. YPSG series toothed roll crusher is mainly used for crushing such large granular material like soybeans, so as to produce the excellent embryo and improve the yield. The machine has the characteristics of small noise, high output, uniform crushing granularity, low power consumption, small footprint, simple structure, flexible and reliable, convenient maintenance and so on.

Softening is through the adjustment of oilseed moisture and temperature to improve the elasticity of seed so that it has the best conditions for rolling. Softening is mainly used for seeds with low oil content, low water content, poor physical properties and hard texture. Soybeans have low oil content and poor plasticity, which need to be softened before rolling. Softening temperature should be based on the level of soybean moisture. When soybean moisture is 13%~15%, the softening temperature is usually controlled at 70~80, and the softening time is 15~30 minutes. The commonly used softener for soybeans is a horizontal softening pot, which has a better softening effect.

The material enters the drum through the inlet, and with the rotation of the drum, the material is constantly turned over. Meanwhile, the drum is equipped with a heating tube and steam is passed through the tube, the material is heated, steamed and rotated at the same time. According to the softening condition of the material, the softening time of the material can be controlled by adjusting the rotating speed of the rotary drum to optimize the softening effect.

The purpose of rolling is to destroy the cell structure of oilseed, increase the surface area of seed and shorten the distance of oil flowing out, which is beneficial to the extraction of oil. In order to ensure the quality of rolled flakes, the moisture and temperature of materials before rolling should be strictly controlled.

Soybean extruding is the process of using extrusion equipment to break through the crushed, rolled soybean into porous, expanded granular material. Extrusion is a kind of high temperature and short time processing. At present, the commonly used soybean extruding machine is low moisture single-screw extruder, and the material is extruded by heating, pressing, gluing and vacuum extrusion. Generally, extrusion temperature can reach 110~200, and the residence time in the extruder is for the l~3 minutes.

Oil pressing is a mechanical extracting method by using screw press to squeeze oil out from clean materials under pressure. The capacity of oil screw press is from 1 to 50 tons per day, which are commonly used for continuous mechanical extraction of oil these days, regardless of the size of the operation. There are many factors that affect the efficiency of oil extraction, such as vegetable seed types, temperature, press configuration, etc. Usually, the physical pressing method has an oil output of 65-70%, which is suitable for commercial processors to build small and medium screw pressing oil plant.

Today, the soybean oil is divided into cold pressed oil and hot pressed oil. The cold-pressed soybean oil has a lighter color and a lighter raw smoky taste. The hot-pressed soybean oil has high oil yield due to the high-temperature treatment of the raw materials, but it has a darker color and a stronger green bean odor. Therefore, the commonly used oil screw pressing method is cold pressing: the physical pressing method has irreplaceable technological advancement for the pursuit of green, authentic, healthy food. In order to achieve additional oil recovery, the seed material must be subjected to a longer retention time of high pressure in the screw press. Higher pressure is mainly achieved by lower seed moisture, resulting in high friction in the press. Because of the mechanical strength, the maximum diameter of the press cage is determined. The higher the pressure, the more limited the capacity of the press is. Moreover, the longer the retention time is required, the lower the shaft speed is required. This further limits the capacity. Therefore, the cold press is characterized by a capacity of only 1/10 of the capacity of the modern pre-pressing machine. But cold press machine can screw out 80~90% oil from seeds. This means that the total remaining oil content in the full-pressed cake is around 10~20%.

Lyzx24 cold press is a new generation of spiral oil press designed for the cold pressing of various oils, especially suitable for mechanically squeezing organic plants and high value-added commercial crops. The cold pressing machine is suitable for squeezing soybean, rapeseed, peanut, etc., Lyzx24 pressing machine could be equipped with single-screw or twin-screw structures. Based on the single-screw press, a twin-screw cold-pressing machine is developed with the improvements of superior mechanical properties and high oil production rate and optimized stamping process, which produces high-quality oil and cold-pressed cakes with high efficiency. If the seed has high oil content, it should be added double press to obtain maximum yield.

This workshop adopts the production technology of batch refining. According to the type and quality of the crude oil, the process parameters are adjusted and different refining methods are selected to produce the first and third-grade oils. The process equipment we provide has the following features:

Liquid soybean oil is sold as vegetable oil or as a component of processed food like margarine, shortening, mayonnaise and various flavoring oils. The refined soybean oil is pale yellow, clear, transparent, odorless, and has a good taste. It can be used for cooking without foam and smoke. It is mainly used as cold salad oil in addition to as the cooking, frying oil. And the remaining soya bean cakes are used as animal feed.

The Soya lecithin, one of the extracts from soybean oil sediments, can also be used in the chemical field. For example, the soya lecithin can be used as antioxidants, color enhancers, catalysts, emulsifiers, grinding aids, and viscosity modifiers in paints and inks. It can evenly disperse pigments, prevent sedimentation, stabilize water-based paints, impart luster to dry film, and improve the fluidity of printing inks; The addition of phospholipids to the paint shortens the kneading time during the manufacturing process and prevents pigment precipitation. And it can produce a good color, increase painting performance, so that the brushing surface is dry, smooth, soft and bright.

what is the process of 'flushing' of production lines? - ifsqn

what is the process of 'flushing' of production lines? - ifsqn

Hello, Anyone can help me in understanding the process of 'Flushing' of production lines? We are producing dry feeds for animals and we have been asked to flush production lines with flour before production. Regards, Rudra

Hello,Anyone can help me in understanding the process of 'Flushing' of production lines?We are producing dry feeds for animals and we have been asked to flush production lines with flour before production.Regards,Rudra

Many thanks sir for you precious reply. I really appreciate it. grateful if you can tell me the amount of flushing material ( in my case its wheat flour) should be sent so that everything which had remained in the process gets removed. Rudra

Many thanks sir for you precious reply.I really appreciate it.grateful if you can tell me the amount of flushing material ( in my case its wheat flour) should be sent so that everything which had remained in the process gets removed.Rudra

^^^ That. If the purpose of the flush is to remove material from the previous produciton run, you need to run the flush product until there is no previous material left. Otherwise, the flush has not done anything to help you. Then there's the flush material itself. If you've been asked to flush your line with flour, I'm assuming a trace amount of flour in the first part of your production run is not an issue?

For quarry crushing plant, it produces a large amount of finished stones every day. The worker should maintain and check the wear conditions timely. If the wear is not serious, repair the device timely, if the wear is serious, and the equipment cant work, replace the components in time.

For maintenance, large machinery equipment need to add lubrication timely. For crusher plant, it is also necessary to add lubricant regularly, which can control the friction between some components. It can also play a role in controlling corrosion when the equipment doesnt work for a long time, which can improve the service life and production efficiency of the equipment.

Quarry crushing plant is related to many production equipment and production flow. The management is also very troublesome. Technicians should guide the production process, investigate and solve a series of problems in production timely, avoid safe problems in production, ensure the efficiency and orderly production of the equipment.

Check whether the lubrication of bearing is good. The lubricating oil should be full of 50% of the bearing capacity in normal conditions. In other case, the lubricating oil become metamorphic and sticky. It needs to clean the bearings and replace new lubricating oil.

It may be that the feed size is too large; the wear of wear-resistant parts is uneven, the counterattack hammer needs to be replaced; the rotor is unbalanced and needs to be adjusted and proofread to balance; check whether the anchor bolts of the equipment are fastened and properly strengthened.

It shows that the wear of the plate hammer or the liner of impact crusher is serious, which causes the gap between the plate hammer and impact plate too large, the clearance of the impact frame before and after adjustment, or the replacement of the liner and the plate hammer; adjust the position of the impact frame so that the clearance between the two sides and the liner plate is uniform; if the liner on the rack is seriously worn, it should be replaced in time.

It is mainly due to belt breakage. Replace triangle belt, pay attention to belt quality, or because of the improper assembly of pulley, it is necessary to adjust the active and driven pulley on the same plane.
