Coal Grinding Mill liner

The lining is the key wearing part of the Coal Grinding Mill, and its performance directly affects the working performance of the Coal Grinding Mill. During the operation of the Coal Grinding Mill, the liner will be continuously worn and shortened. Therefore, the wear mechanism of the liner is analyzed, and the correct decision is made to select the wear-resistant material of the Coal Grinding Mill, which greatly improves the production capacity of the Coal Grinding Mill.

Reducing the wear rate of the Coal Grinding Mill liner can be achieved by improving the grinding process or by selecting and processing the liner material. The basic requirement for selecting the lining material is to have high wear resistance under certain impact loads, mainly including three aspects: the overall hardness, composition and structure of the lining plate; high impact fatigue durability, energy It resists the impact of a certain strength; it has a low wear rate and is not deformed or broken during use.

The liner of the Coal Grinding Mill mainly bears the loads such as instantaneous impact force, sliding friction force and rolling friction force of the ball and material. For the dry Coal Grinding Mill, the lining wear is mainly caused by repeated repeated impact loads and fatigue damage. The wear of the chiseling abrasive is mainly in the grinding chamber, and the wear of the grinding and scouring abrasive is supplemented; in the fine grinding chamber, the opposite is true. For wet Coal Grinding Mills, in addition to the above wear, the wear and tear is dominant.

The wear rate of the liner is proportional to the impact energy of the sphere, and the impact energy of the sphere is proportional to the diameter of the cylinder, that is, the wear rate of the liner is proportional to the diameter of the cylinder. Production practice shows that the wear rate of the liner is related to many factors such as the production process layout, the structure of the liner, the operation of the Coal Grinding Mill, and the filling rate of the sphere. In addition, the ratio of the hardness of the lining to the hardness of the material also directly affects the wear rate of the lining. Since the hardness of the lining material is higher, the wear resistance is better, so the purpose of extending the service life of the Coal Grinding Mill lining can be achieved from the way of improving the hardness of the material.
