Crusher crusher use as a model for the broader roll crusher classification, the aircraft's crushing ratio, for coarse, medium and fine crushing medium hardness brittle materials, such as limestone, dolomite, shale, sandstone, coal, asbestos, graphite and rock salt, etc., Dan Zicheng type rates are generally better · 24 stones 12 stones. Is broken in two choice. First, to be clear, what is the one? What is two? Of course, there are three. Primary crusher is mainly the larger stones were once broken, after completion of primary crushing stones, grain size is much smaller, but to achieve the effect of fine sand, but also for secondary crushing. Crusher is two broken one, but not with the third stage crusher - compared to vertical impact crusher. Because crusher crushed stone, particle shape is cubic in. So roll crusher manufacturers, crusher used in highway construction relatively more. Crusher generally handle larger pieces of material, product coarser, usually greater than 8 mm. Its structure is characterized by a certain gap between the crushing member, is not in contact with each other. Crusher can be divided into coarse crusher, the crusher and crushing machine. Generally mill processed materials smaller product size is fine for roll crusher models, up to 0.074 mm on the roll crusher, fine or even more. The structure is characterized by broken parts (or medium) contact with each other, the medium used is steel balls, steel bars, gravel or mineral mass. But some machinery is with both crushing and grinding action, such as from the mill. ∮5.5 × 1.8 米 since the mill processed ore particle size limit of up to 350 to 400 mm of roll crusher classification, Naidong to roll crusher, Xin Li Heavy provided by Xin Li Gongyi City Heavy Machinery Manufacturing Co., Ltd. .
