Crusher crusher as the wider use of a model, 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, such as roll crusher classification, 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, high-roller crusher, 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 broken in two kind of roll crusher manufacturers, however, not with the third stage crusher - compared to vertical impact crusher. Because crusher crushed stone, particle shape is cubic in. Therefore, the crusher used in highway construction relatively more. Crusher can be divided into categories according to medical Crushing and Mining crusher. The mining crusher principles adapted to the massive mining of hard rock crusher roll crusher, the expected size of its typical granite ≤40mm 90%, the machine can handle the side length of 100 to 500 mm below the material, the compressive strength of up to 350 MPa, with a crushing ratio, after crushing the material advantages of cubic particles. Gravel mining machinery refers to the row of feed particle size greater than three millimeters content more than 50% of the total discharge quantity of crushing machinery.
