28r/Min Raymond Roller Mill

Energy-Saving Ball Mill Used In cement, silicate products, new building materials,refractory materials, fertilizer, black and non-ferrous metal processing and glass and ceramics production industries

Introduct:

Ball mill is the key equipment for crushing materials after being crushed, which is mainly composed of feeding part, discharging part, rotary part, transmission part (reducer, small transmission gear, motor, electric control), etc. Ball mill has a good effect in energy saving and consumption reduction, production increase, green environmental protection and other aspects. It can grind various ores and other grindable materials dry or wet. It is widely used in cement, silicate products, new building materials,refractory materials, fertilizer, black and non-ferrous metal processing and glass and ceramics production industries. 

Advantage:

1. The operation and maintenance of the gear unit is more convenient and reliable, and the maintenance of the gear is more convenient and reliable.
2. Good wear resistance: the hollow shaft is made of cast steel, the lining can be disassembled and replaced, the rotary gear is processed by casting gear hobbing, and the cylinder body is inlaid with wear-resistant lining plate, which has good wear resistance.
3. Long service life: the planetary gear system is changed to planetary roller system, and the complete rolling friction transmission between metal wheel and wear-resistant polymer material wheel is adopted to reduce noise and wear to a minimum, and there will be no gear fracture and damage during operation and operation, which greatly extends the service life of the gear.

Working Principle:

When the ball mill is working, the material is loaded into the cylinder by the hollow shaft at the feeding end. When the ball mill cylinder rotates, the grinding body is attached to the cylinder liner due to the inertia, centrifugal force and friction force. When it is carried to a certain height, it is thrown down due to its own gravity. The falling grinding body smashes the materials in the barrel like a projectile. The material enters the first bin of the ball mill evenly by the feeding device through the feeding hollow shaft. There are stepped lining plates or corrugated lining plates in the bin, which are filled with steel balls of different specifications. The rotation of the cylinder produces centrifugal force, which brings the steel balls to a certain height and then falls down, which has a heavy impact and grinding effect on the materials. After coarse grinding in the first bin, the material enters the second bin through the single-layer partition plate, which is inlaid with flat lining plate and steel ball inside to grind the material further. The powder is discharged through the discharge grate plate to complete the grinding operation.
