Wear Causes of Cement Grinder Roll

Wear Causes of Cement Grinder Roll

Cement Grinder Roll is an important grinding part of vertical mill. Its shape design must make the material to be ground form a uniform and stable material bed on the grinding disc.
Therefore, the reasonable shape of the grinding disc and the suitable grinding roller play an extremely important role in stabilizing the material layer, improving the grinding efficiency and reducing the grinding consumption.

The looseness of the roller skin caused by the impact and vibration is an important factor causing the wear of the roller core of the vertical grinding roller.

The vertical mill bears huge shocks and vibrations during operation, and the roller skin should be fixed by regularly tightening and pre-tightening bolts several times at the beginning of installation to prevent the roller skin from loosening.
However, in the actual production process, most enterprises cannot effectively and timely tighten the bolts of the pressure plate, resulting in the loosening of the roll skin and the gap between the mating surface of the roll skin and the roll core.
In this way, it is easy to cause the impact of the mating surface, which in turn leads to the impact wear of the surface of the roller core, and the mating gap is further increased.
At the same time, due to the generation of gaps, the scouring of dust materials in the mill is also one of the important factors that lead to the increase of the gap between the mating surfaces.
In addition, the metal fatigue wear of the core material is also a factor that causes the gap.

Coal mills are subjected to huge shocks and vibrations during operation. Most enterprises cannot fasten the bolts of the platen effectively and in time, which leads to the loosening of the roll skin and the gap between the matching surface of the roll skin and the roll core.
In this way, it is easy to cause the impact of the mating surface, which in turn leads to the impact wear of the surface of the roller core, and the mating gap is further increased.
At the same time, due to the generation of gaps, the scouring of dust materials in the mill is also an important factor that increases the gap between the mating surfaces.

The vertical mill has always held more than half of the market share in the world cement industry, and is one of the world’s first-class cement machinery and equipment.
Leading the continuous innovation and development of modern cement industry technology and equipment.
During the long-term continuous operation of the vertical mill, due to the influence of various factors such as the environment or materials, the problem of damage to the roller core of the vertical mill often occurs. Once such problems occur, the general repair methods are difficult to solve, and the replacement cost is high.

Cement Grinder Roll

The raw material vertical mill of Arab Cement Company’s 5000t/d cement clinker production line has been affected by factors such as the clearance of components and material scouring since its operation, resulting in problems such as damage to the vertical mill Cement Grinder Roll.
Jk Cement is procuring related spare parts from AGICO CHINA and introduce info@cementplantparts.com to more cement plants.

The reason for the damage is that the vertical mill is subjected to huge shock and vibration during the operation. The roller skin should be fixed by regularly tightening and pre-tightening bolts several times at the beginning of installation to prevent the roller skin from loosening. However, in the actual production process, most enterprises cannot fasten the bolts of the pressure plate effectively and timely, which leads to the loosening of the roll skin and the gap between the mating surface of the roll skin and the roll core. The impact wear is further increased, and the matching clearance is further increased. At the same time, due to the generation of gaps, the scouring of dust materials in the mill is also one of the important factors that lead to the increase of the gap between the mating surfaces. In addition, the metal fatigue wear of the core material is also a factor that causes the gap.
