The main factors controlling the jaw wear material is its hardness and toughness. Hardness of the material determines the material indentation depth and size. Composite material hardness high performance crusher, material pressed into the jaws of shallow depth, a small degree of deformation of the jaws of the cladding material, while the material sliding short-cut materials less volume. Toughness indicates its ability to resist breakage. Toughness is good, you can eliminate the material brittle fracture during extrusion of composite crusher, jaw and makes the material deformation fatigue deformation process before the formation of wear debris is greatly increased. Jaw to withstand wear and tear in the use of plastic deformation and cutting wear, therefore, require the use of materials with high hardness to resist plastic deformation fatigue, but also has a certain toughness to prevent brittle flaking or fracture. In the actual jaw material selection, we must fully understand the working conditions and the wear mechanism of composite crusher models, rational use of jaw plate material. The larger size jaw crusher, crushing blocks of material, the greater the degree of high-quality composite crusher, jaw withstand greater impact loads. In this case, the choice of material, you should first consider increasing its hardness and toughness in ensuring the jaw premise. PF Series Impact Crusher is my company in the absorption of foreign advanced technology, combined with the mud gravel mining industry specific conditions and the development of the latest generation crusher, the device has a crushing ratio, after crushing materials cubic particles, wear pieces of long life, etc., after the user has made to promote the use of the obvious economic benefits. Main purpose: This series crusher is suitable for building materials, mining, metallurgy, chemical industry broken limestone, clinker, coal and other ore crushing operations, but also can be used for dolomite, flint, lead and zinc, serpentine, high slag crushing operations, coal, phosphate rock and other medium hardness of materials, especially for artificial sand or stone pavement highway machining of hard limestone, dolomite, granite, basalt crusher. Its compressive strength of not more than 140 MPa humidity less than 15%.
