A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.

crusher cavity are: • Abrasive wear • Fatigue wear The main wearing mechanism in crusher cavity is abrasive wearing. Fatigue wear is also present as wear part are subjected to multiple compression or impact loads. Abrasive wear (or abrasion) Crushers typically compress the feed materi-al between the fixed and movable wear parts.

Hammermill Crushers are known to generate material finer than 3/16" (4mm), which in some applications may be undesirable. However, if there is a market for finer material, or if it is acceptable within the desired product size, Hammermills can achieve reduction ratios that may otherwise require multiple crushers.

The Bond Abrasion Test determines the Abrasion Index, which is used to determine steel media and liner wear in crushers, rod mills, and ball mills. Bond developed the following correlations based on the wear rate in pounds of metal wear/kWh of energy used in the comminution process.

Similarly, in rock-drilling, a hard rock demands a tough tool, whereas a soft rock demands a hard tool. These facts are quite in agreement with the experience that a tough rock causes most abrasion on a hardened steel, but if the steel is soft, or work-hardening has not occurred, then a hard brittle material may be very abrasive.

5.1 A number of types of jaw crushers have been used for laboratory abrasion tests, see Refs (1-5) 4 and a limited amount of data has been published (6-10).With emphasis on the crusher described in Section 6, this test method ranks materials and also indicates differences in wear life for that type of abrasion defined as gouging abrasion, as is found in crushing equipment and in many mining ...
