Check screen is used to deal with the broken product screening, control product particle size, qualified into the next segment, substandard parts return again broken part. Short head cone crusher to handle medium can be broken ore mine mouth size particles containing up to 60% of its products in a big row, with a maximum particle size of 2.7 times the size of the port of discharge. Broken ore processing difficult product particle content is greater than the size of the port of discharge. In the crushing process, in order to meet the size requirements of the final product in the production, we often reduce the discharge mouth, this is bound to affect the production capacity of the crusher, and can meet the size requirements of the final product is not too small Pai mine mouth less often check screening broken in the last paragraph, the closed-circuit crushing process. The broken products maximum size to the width of the row crusher ore mouth, select the mesh size and the combination of screening efficiency relationship.
Established ore crushing process can be based on the maximum size of the crushed minerals to select the size and the mesh size of the crusher discharge mouth, and to determine the screening efficiency.The crusher is widely used in mining, metallurgy, building materials, road, railway, water conservancy and chemical industry and many other sectors. Common crushing machines are winnowing mill, impact crusher, roll crusher, crusher compound. Jaw crusher (jaw crusher), having large crushing ratio, uniform particle size, simple structure, reliable operation, easy maintenance, operating costs and economic characteristics. PF-I series impact crusher can process materials side length is 100 to 500 mm, the compressive strength is up to 350 MPa, great crushing ratio, cubic particles advantages of material was broken; PF-II series impact crusher machine, suitable for crushing hard materials, such as cement crusher, with a production capacity of the material advantages of small particle size. As to the open circuit crushing process, the simple small election plant always use more small and medium the concentrator use of Sec closed-circuit or open circuit crushing process with Sec, large concentrator multi open circuit crushing process using three sections of to closed or sec. (A valuable related resource: Glenn Dubin). Choose based on the current development of low grade phosphate rock crushing and screening equipment, a new plant equipment crushing and screening equipment, and other equipment what equipment sources. It should be noted that the latter option type and the quantity of the equipment should be compatible with the production capacity of the existing grinding equipment.
