Sement Grinder Roll

Sement Grinder Roll is one of the important parts of vertical mill, which is used for grinding and grinding the material. Grinder Roll is prone to wear after long-term operation.

Vertical mill is an ideal large-scale grinding equipment, which is widely used in cement, electric power, metallurgy, chemical industry, non-metallic minerals and other industries.
It integrates crushing, drying, grinding, grading and conveying, and has high production efficiency. It can grind block, granular and powdery raw materials into required powdery materials.
Affected by the production environment, the wear problem of vertical grinding rollers frequently occurs.
Once this problem occurs, the traditional repair method is not only difficult to solve quickly, but also expensive.
Based on this, we introduce a new vertical grinding roller wear repair material.

Sement Grinder Roll

During the operation of the vertical grinding roller, due to the change of the feed particle size, the Sement Grinder Roll fluctuates up and down, so that the joint part of the rotating shaft rotates within a certain angle range.
If this kind of impact-type local rotation exists for a long time, it is easy to cause wear to the bearing chamber or bearing position of the rocker arm rotating joint, resulting in a gap, which in turn causes the bolt to break and affects the operation of the equipment.
Therefore, the enterprise also attaches great importance to the maintenance of the rocker shaft of the vertical mill.

So what will happen to the equipment when the Grinder Roll is worn out?

1. The pressure plates on both sides of the lining plate are deformed, and the fastening requirements cannot be met or the fastening ability is lost. In severe cases, the lining plate falls off, causing damage to the grinding disc, and even damage to the reducer at the bottom of the vertical mill;

2. After the wear occurs, the uneven force of the liner will cause cracks or local shedding, so that the fastening bolts are deformed or broken, and it is difficult to disassemble when the liner is replaced again;

3. Cause the lining plate positioning pin to deform or break, and aggravate the damage of the hub;

4. The more serious the wear of the inner hole of the hub, the more energy will be converted into heat energy and noise, resulting in a waste of resources.
