Cement miller is the key equipment for grinding after the crushing process, and it is widely used in the manufacture industries, such as cement, silicate, new building material, refractory material, Fengde, ferrous metal, nonferrous metal and glass ceramics, it also can be used for the dry and wet grinding for all kinds of ores and other grind-able materials.
Cement miller main wear mechanism:
1. The cement mill deformation wear. Grinding balls and material relative sliding and mutual impact, in addition to withstand cutting and chisel cutting wear, and furrow deformation and chisel cutting deformation with occurs, the metal is pushing oppression to groove and the edges of the pits of lateral, in repeated action and metal deformation repeatedly, because of strain fatigue crack, crack extension, connection, form the plough cut sheet from grinding ball table and fall off.
2. Fatigue wear. In mill grinding body in motion rise phase by repeated sliding and rolling, in drop stage by repeated impact, in the unceasing impact stress, contact stress and shear stress, under the action of the grinding ball in the surface of fatigue crack, crack parallel surface extension, and to the surface extension form flake layer. As in the surface of casting defect at nuclear, expansion will lead to the macro fatigue spalling.
3. The cement grinding machine cutting and chisel cutting wear. Grinding ball in the mill in sports rise phase and material relative sliding, the material component of hard cutting out deep groove, the soft material with the ball cutting relatively shallow, to a certain Angle contact material, material for grinding balls produced local chisel cutting wear, form the chisel cutting pit.
4. Brittle flaking. Grinding balls under impact process, the brittle phase cracking and crushing, since surface spalling, causing wear.

The impact crusher for sale produced by our company is a kind of mining equipment professionally used for breaking ore; and it is also called mining impact crusher or stone impact crusher.
Impact stone crusher is widely used in all kinds of minerals, railway, expressway, energy, cement plant, chemical industry and other industries. The reason why impactor crusher is so popular is because of there are some following advantages:
1. Impactor equipment can deal with the materials of large moisture efficiently to prevent the blocking phenomenon of crusher. In dealing with the materials of large moisture, the feeding chute and back plate of impact crusher can install heating devices to prevent the bonding of materials and the impact crusher must set up the bottom screen board to avoid the blocking phenomenon.Hammer crusher can’t adopt the heating method to avoid the bonding of materials, and must install the bottom screen board.
2. Stone impact crusher can adjust the discharging granularity by many ways such as rotor speed, back plate, the gap of the grinding chamber etc. The gap of the grinding chamber can be adjust by mechanical type and hydraulic type, and adopting hydraulic type can complete the adjustment of the gap by the manual button box or remote control system conveniently. Hammer crusher machine adjust discharging granularity by replacing the bottom screen board.
3. Impact crusher is applied in both soft materials and hard materials: The board hammer of impact crushing machine is fixed at rotor adopted mechanism, and it appears moment of inertia as the rotor moves. The rotor of impact stone breaker shows larger momentum and can crush harder materials relative to hammer crusher, and has a low consumption.
4. The abrasion of wear parts of impact breaker is less than hammer crusher, and the metal utilization is high, it can reach by up tp 45%-48%; what"s more, the spare parts of this crushing machine change simply, so the maintenance charge can reduce.Since its inception, has been widely recognized and trusted by customers, which creates enormous economic benefit for enterprises. Hongxing Machinery is the manufacturer that always make customers reliable and rest assured. For many years, Hongxing Machinery adheres to the principle of using technological progress to ensure quality enhancement of products, which brings real benefits to customers and realizes win-win situation between customers and company.
