Problems and solutions about cement ball mill

Ball mill is the largest consumption equipment of mining plant. The ball mill’s operating state directly influences the whole mill plant productivity. Therefore, it is very important to maintain and overhaul the ball mill regularly, reasonable and effective maintenance can promote the cement ball mill’s operational rate and service life.

1. Repair cement ball mill wear parts

Problems: The roller body and liner of cement ball mill are worn during use. Once the gap is matched, the wear between the roller body and the liner will be aggravated, coupled with the high temperature on the surface and the continuous erosion of cement particles, resulting in the generation of grooves, resulting in the roll body collisions between them. Serious cracks or breaks occur in the body, cylinder liner, and cylinder liner, which will damage the machine, especially the gearbox, and cause serious accidents.

Solutions: Once such problems occur, the general maintenance methods are difficult to solve, and the replacement cost is high. The excellent mechanical properties and good plasticity of polymer composite materials make this problem easily solved.

2. Cement Mill roller bearing chamber wear repair

Problems: The assembly requirements of cement mill roller bearings are relatively strict, and enterprises generally use dry ice to cool the bearings during the assembly process. Once there is a gap between the bearing and the bearing chamber, it will affect the normal operation of the bearing, cause the bearing to heat up, and seriously cause the bearing to burn out.

Solutions: Salvo Blue technology is fast, simple, easy to operate and in many cases field repairable.

3. Cement Mill reducer leakage control

Problems: The oil leakage of the reducer of the mill not only affects the appearance of the machine, but also wastes lubricating oil, causing great trouble to the repair and maintenance of the equipment.

Solutions: The rubber repair material for 3223 fast-curing material cannot be shut down, and the oil leakage site is treated, which is easy to operate and has a good control effect.

People Also Frequently Asked- FAQ:

1.How do you maintain a ball mill?

During the ball mill operation, you should check the condition of all the lubricating points and the oil level height, at least once every 4 hours, and at the same time make sure that the temperature of the main bearing lubricating oil is not more than 55 ℃.

2. What kind of liner does a ball mill use?

What are ball mill liners made of? Ball mill liners are available in rubber or rubber composite materials that is alloyed casted in steel or wear resistant cast iron.

3. How much does it cost to fill a ball mill?

When grinding bulk materials, the jar should be filled with approx. 1/3 sample and 1/3 ball charge. The remaining third is the free jar volume that is necessary for the free movement of the balls.
