The mining machinery manufacturers should improve the quality of aggregate sand, which is the inevitable choice of the plant. The selection of the crusher and sand maker is especially important. The general aggregates production process is as following. After the rocks are primarily crushed through the jaw crusher, you can choose the impact crusher or the cone crusher for moderate according to the hardness of the stone crushing and the yield. Finally, the stones are crushed to the standard aggregate particles through the sand maker. The wet sand making is required to be equipped with the sand washer to clean and wash the sand and gravel materials, which finally become the clean and high-quality construction sand and gravel material. Here is brief introduction about the choice of crusher Hammer crusher hammer crusher ring), also named hammer breaker, is mainly suitable for crushing all kinds of mineral materials brittle.
Material that can be crushed by it includes coal, salt, white sub, gypsum, alum, brick, tile, limestone, etc. Impact crusher: also known as sand making machine, is widely used in a variety of rock, abrasives, refractory, cement clinker, quartzite, iron ore, concrete aggregate and other hard materials in the broken, fine(made of sand) PCL series impact crusher(sand making machine) is perfect on the construction sand, gravel roads. Roll crusher: also named roller crusher, is suitable for mineral processing, chemical, cement, building materials and other industry sectors in a variety of medium hardness broken and the crushing of ore and rock. Jaw crusher: features crushing ratio, even coexistence, simple structure, reliable operation, easy maintenance, operating cost and so on. In order to get excellent grain type products and reduces the production costs at the same time, and then we need to add a laminated between the jaw crusher and the crusher impact crusher. For example, we can use fine jaw crusher and the cone crusher. This configuration can make the crushing work completed by the primary crushing and the secondary crushing and finally by the impact crusher crushing integer. This configuration process can greatly reduce the reverts formado por screening. I too high ration of the reverts in a production line will make the final crusher increase excessive and repeated crushing work, which will make the wear of the wear parts greatly increase correspondingly.
