Stone artificial sand making machine construction, roads, railways and other industries with sand and stone dedicated production lines , mainly by feeder, jaw crusher , impact crusher , vibrating screen, vertical impact crusher and other equipment , with belt conveyor consisting of a complete stone production line . At configuration time , not only to consider the different processing to meet customer needs , but also note the following specific factors .
① productivity. Productivity is an important crushing and screening equipment parameters , productivity requirements include two elements, one particle specifications productivity , and the other is the productivity of the entire product. For engineering , the productivity of each particle size products more meaningful. Therefore, in determining the productivity of the equipment , you should first consider the actual needs of the project.
② product quality requirements . Quality of the product has a particle size , size distribution, particle shape and other products in different projects, product quality requirements are not the same , the quality of products processed with broken machinery and production processes related.
When the particle size is small, the total crushing and screening equipment crushing ratio is relatively large, the product of the grain size , the more complex equipment . Sometimes in order to get a variety of grades of gravel , can be dedicated to an independent screening machinery for grading . In many projects, the dust content of gravel compound should not be too high , the quality of the concrete dust harmful . When excessive levels of dust , it is necessary to increase a cleaning process .
③ characteristics of raw materials. Hardness of materials , grading , clay content and moisture content is very important parameter , different materials should choose a different crushing and screening machinery. Hardness of materials is large , generally choose jaw crusher , cone crusher as...
