Wear causes of cement linings

- Oct 06, 2019-

(1) The temperature of the milled material is too high (about 130 °C), and the liner is in a state of high temperature wear for a long time.

(2) The wear of the coarse-grinding end lining is mainly caused by the high-stress impacting of the grinding body, and the extrusion cutting is supplemented. The grinding body close to the lining is brought up by the step lining of the grinding machine and thrown under the action of centrifugal force. One or two turns in the impact end liner and a ring plate in the middle of the partition plate.

(3) The fixing bolts of the partition plate and the end lining plate are distributed at the four corners of the raft, and are relatively weak relative to the four corners. The bolts are expanded around the bolt hole under the impact of the grinding body (see Figure 1). The board loosened and fell off.https://www.wuxiorient.com/
