Broken materials series, abrasive material wear of tools, grinding tools (jaw pull plate hammer ) its size will affect the amount of wear and service life of the smash tool.   in addition to the design of the ectoplasm Smash degrees is also related to the nature of materials, heat treatment, and shredders wear generated by the impact wrench, ball and lining, etc. Which also related to the force types, methods of operation, grinding tools, materials, and parameters.
 

There are several ways about abrasive test , but there is no system of regulations, different ways to measure the abrasive, they can only approximate the given materials crushed tool wear for the grinder and its operating parameters is called a reference. The abrasion test device can also be used for the comparison made by a variety of materials crushed the relative wear resistance of tools and forecast to crush the life of the tool. This test is required when selected several materials to manufacture grinding tools (such as leaves).
The crusher is widely used in many sectors of mining, smelting, building material, highway, railway, water conservancy and chemical industry. The commonly used gravel machines are: jaw crusher, crusher, winnowing mill, hammer crusher, impact crusher, roll crusher, compound crusher and so on. The jaw crusher (jaw crusher)has a big crushing ratio, even granularity, simple structure, reliable operation, easy maintenance, low operating cost. Side of the PF-I series of impact crusher can process 100 to 500 mm long and the following materials, the compressive strength is up to 350 MPa, with broken than large, the material was broken cube particles, etc.; PF-II series impact crusher machine,which is suitable for hard materials in the crushing, such as cement plant limestone crushing capacity, discharge size is small   these advantages.
