In the 21st century, the development and progress of industry can not do without environment protection, and the material crushing plays an important in it. The main materials for was crushing are striking, rolling, crushing and grinding, which can improve the crushing efficiency and crushing effect. The common crushing equipments are as follows.The first is the ball mill. Generally speaking, the ball mill is the key milling equipment after material has been crushed. It is widely used in cement, silicate, new construction material, chemical fertilizer, ferrous metal and non-ferrous metal as well as ceramics.
It is widely applied to dry or wet grinding for Owers and grindable materials.The second is the stone crusher. Hongxing VIC series vertical stone crusher is the newest realistic type product which is researched on the basis of American Barmac technology and combining the current demand of China sand making industry. It has the features of large capacity, low energy consumption, good finished product shape, easy to repair and convenient to operate and so on.The third is the Cone crusher. Hongxing Cone crusher is used for crushing of Owers and rocks, the advantages are reliable structure, high efficiency, easy to adjust and economical. The safety spring system is the overload protection device, which makes foreign material goes through the machine without bring any hurt to it. The sealing modes are oil and water, which segregate the stone powder and lubricating system. The crushing chamber is decided by the purpose of ore, the standard model is suitable for medium crushing; the medium model is suitable for fine crushing and the short head model is suitable for fine crushing.The fourth is the Raymond Mill. The Raymond mill is mainly used for the highly fine processing of 280 pipes in some trades power of non-flammable mine, chemical industry and building materials, etc., and the material have the Moh s scale less than 9.3 hardness level and the humidity of less than 6%, including barite, calcite, potash feldspar, pencil stone, marble, limestone, dolomite, fluorite, active carclazyte, coal act, NW, kaoline, cement, phosphorite rock, gypsum, glass and heat insulating materials etc. The particle size of finished product can be adjusted from 80 325 meshes at random and the particle size of materials part can reach 2000 meshes at the maximum.
