Broken accessories series, material abrasive wear of tools, grinding tools (jaw plate hammer pull) 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 pipes 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, crusher and so on compound. The jaw crusher (jaw crusher) has a big crushing ratio, even coexistence, 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. Since the content is closely related to the materials of the rock or ore so abrasive, and thus in some cases only by the material Si0, content (or Si0, equivalent content) to select the grinder or to determine its operating parameters. Test abrasive blade abrasive measuring device, the abrasion test, corrosion test devices, blade abrasion measuring device and Si0, content and its application of the abrasive. In the mining industry, the fragmentation process is very important, so this part of the extra attention, we must give careful consideration to the choice of mineral processing equipment, look at the choice of what kind of crusher in order to better beneficiation process to proceed smoothly.
