aggregate application for green sandstone industry - hongxing machinery
The green development of the aggregate of sand and gravel has been the focus of the mining industry(like Hongxing Machinery). Studies have shown that sand aggregate has become the second-largest consumptionof humans, which ranks onlysecond to freshwater. Currently, like high-speed railways,highways,and tall buildings. Almost every construction of the building does require a lot of sand and gravel aggregates.So what is the aggregate?Follow us and read below!
As is known, the aggregate plays an essentialrole in filling and erectingonthe concrete, and it takes on the shape of loose granular. It canalso make a contribution toimproving the durability and stability of the concrete.
Whats more, according to the density, it is grouped into ordinary aggregate and light aggregate. Fine aggregates with a particle size between 0.15 and 4.75 mm are commonly known as sand, and coarse aggregates with a particle size between 4.75 and 9.0 mm are commonly known as a stone. Due to the gradual depletion of natural sand and stone aggregates, while the artificial sand and stone markets become hotter. Mechanical equipmentcan process various materials such as the slag(rock, waste, etc.) into the required particle size, for example, The PEX jaw crusher of Hongxing Machinery can crush various aggregates with different hardness.
The choice of the aggregate production line is an important part of modern aggregate production. The complete production line consists of four major systems: the feeding system, the crushing and sand making system, the screening system, and the sorting system.
The lightweight aggregate produced by this process is a ceramic chemically neutral product that may have a wider range of applications than natural aggregates due to its physical properties. It has the advantage of being lightweight and durable with a bulk density of 550 to 720 kg / m3 (35-45 lb / ft3). It is suitable for concrete manufacturing, including prefabricated road construction and construction applications.
At this stage, the bulk materialor brittle materialin the gravel aggregate ore is pre-crushed by the hammer crusher, and the debris that is not suitable for crushingwill besortedout, and the waste wood, plastic, and other debris are removed to facilitate the nextprocess. The initial magnetic separation is performed to remove the scrap iron in the aggregate.
Firstly, the raw materialwill be crushed by a jaw crusherin the first stage, and the vibrating feeder will feed themimmediately, and the large-sized gravel aggregate is crushed into a smaller particle size by using the jaw movement. The coarsely broken material is transported by the conveying equipment to the transfer pile. The material can then be finely divided and shaped using a sand making machine, and the aggregate size of the aggregate after the sand making machine is uniform.
At this stage, a kind of circular vibrating screen manufactured by Hongxing Machineryis used to divide the concrete aggregate fracturedcoarselyinto a block of 0-40 mm and thecrushed material of 5 mm or less. The coarse aggregate of 5-40mm can be directly used for the general C15-C20 concrete production. Fine aggregate can be transported to the intermediate stack for the next process.
During the crushing process, the fine aggregate can be pulverized again by using a ball mill. The secondary screeningcandivide the crushed aggregate into 5-20mmwith high-qualityof recycled aggregate, which can be used for C25-C30 concrete production. The third-stage screening can sortout the recycled fine aggregatewith high qualityin 0.15mm-5mm and fine powder below0.15 mm.
According to the development trend and market demand of the industry, the vu high-quality aggregate optimization system introduced by Hongxing Machinery, the finished sand and stone grain shape is round, the gradation is reasonable, the powder content can be controlled, and the quality is in accordance with the national standard, and the production process is zero silt, zero wastewater, no dust, which fully meets the requirements of national environmental protection.
The VU aggregate systemenjoys the feature with intensity, friendlyenvironment, large-scale automation has brought new development opportunities for sand and stone aggregate, dry mixing, commercial mixing, pipe pile, cement products, and other mining industries.
The full-closed conveyance, production and negative pressure design of dust-removalshall be equipped with a humidifying stirrer to ensure that the water content of the finished sand is qualified, and the production site is free of dust.
Theforeigncustomer has been working with HongxingMachinery for many years. With the market demand for stone materials increasing significantly, the customer once again contacted Hongxingto create a high-performance, high-intelligence, high-environment crushing sand production line. At present, the production line is stable in production, large in output and good in grain size. Once the tower boutique sand is launched, it is in short supply!
The continuous high pressureon environmental protection, coupled with the key pollution control of this dust hazard, for the sand and gravel aggregate industry, transformation and upgrading is an inevitable choice.
The construction of green mines has risen tothe action ofnational. Under the background of the industrial civilization transferringto ecological civilization, the construction of green mines is the general direction, the big principle, the big logic! Saving economy, environmental friendliness and harmonious mining are the development model of green mining.Especially for the Hongxing Machinery.
In the process of mining and sand and gravel production, dust emission should meet the requirements of GB16297; for areas with strict environmental protection requirements, more effective measures should be taken to control dust emissions and meet local environmental protection requirements.
Hongxing company hasestablisheda dust-detection network and evaluation system, prepare a detection-control plan, and regularly organize third-party monitoring and self-monitoring for the detection and control objects.
Dust-controlsystemin miningexploitationand sand production should follow the source control, process coordination control, end monitoring, system linkage and integration of management ideas to achieve environmental protection and energy-saving and clean production.
The mining area should be equipped with the sprinkler, high-pressure sprayer and other equipment to suppress and reduce dust from unorganized dischargingdust, and water fog humidification, dust removal,and thedrilling technology should be adopted to collect dust in the process of the air return of gas pipeline.
Generally speaking, the configuration of the aggregate production line needs to be combined with the users working conditions, time production, finished product size, energy consumption, etc.And there arethe common equipment combination formsof the aggregate production line:
In addition, the impact rock crusher used for crushing brittle materials. As one of Hongxing series like Vertical ShaftImpact Crusher(shorted from VSI)is widelyused for crushingof hard andbrittle materials, such asrock,grindingmaterial, refractory material, cement clinker.
The above is the introduction of aggregate and the production process of aggregate. If you are considering investing in sand and gravel aggregate production lineand ask about price issues, please contact HongxingMachinery, we will customize the production line according to your needs.
environmental impact of quarrying of building stones and laterite blocks: a comparative study of two river basins in southern western ghats, india | springerlink
Mining and quarrying for minor minerals impart significant economic, environmental and social impacts in and around the affected areas. The problem is severe in the small river catchments as the effective area available for assimilating negative impactsof the activity is minimal, compared to large river basins. To address these issues, an investigation has been carried out in two river basins of southern Western Ghats (India)the NetravatiGurpur and PeriyarChalakudy river basins. Both these basins host two important port cities of south IndiaKochi and Mangalore. The study reveals that about 6.75106ty1 of hard rocks are being extracted in the NetravatiGurpur basin through 64 quarries. At the same time, the total number of quarries and extracted amounts in the PeriyarChalakudy river basin are 525 and 10.47106ty1, respectively. Many hillocks in the region are turned to a cluster of ugly scars, degrading the ecology and aesthetics of the area. Lowering of water table, modification or disappearance of natural drainages and environmental pollution are some of the other observations noticed in the area. The environmental impacts of laterite quarrying are comparatively less than that of rock quarrying as removal of the hard laterite cap rock enhances water percolation and makes the area more irrigable for agriculture. The study stresses the need for environment-friendly quarrying alternatives with stringent guidelines to improve the overall environmental quality of the area on one hand and to meet the developmental requirements on the other.
