Ball mill application:
Ball mill is the key equipment for recrushing the materials after they are primarily crushed. It is an efficient tool for grinding various materials into powder. There are two ways of grinding: the dry process and the wet process. It can be divided into tabular type and flowing type according to different forms of discharging material. Ball mill is widely used in metallurgy, mining, chemical, cement, construction, industrial and mining industries etc.

Ball Mill Working Principle:
The ball mill is a horizontal rotating device transmitted by the outer gear. The materials are transferred to the grinding chamber through the quill shaft uniformly. There are ladder liner and ripple liner and different specifications of steel balls in the chamber. The centrifugal force caused by rotation of barrel brings the steel balls to a certain height and impact and grind the materials. The grinding materials are discharged through the discharging board thus the grinding process is finished.

Ball Mill Structure:
The machine is composed of feeding part, discharging part, turning part and driving part (reducer, small driving gear, electric motor and electric control). The quill shaft adopts cast steel part and the liner is detachable. The turning gearwheel adopts casting hobbing process and the drum is equipped with wear-resistant liner, which has good wear-resistance. The machine is with stable and reliable working condition. Moreover, according to different materials and discharging methods, there are dry ball mills and wet ball mills for choice. 

Ball mill features:
1. The machine is made up of feeding part, discharging part, gyre part, transmission part (reducer, small transmission gear, motor, and electrical controller) and so on.
2. The hollow axis adopts the cast steel and the lining can be replaced. The big rotary gear is forged from cast rolling gears. 
3. The barrel body is inlaid with wearable plates.
4. The machine runs steadily and efficiently.

Ball mill advantages:
1. High milling efficiency
2. Mechanically simple design
3. Competitive capital cost
4. Use of low cost
5. No steel contamination of product
6. Capacity to operate continuously at full load power draw
7. Low rotational impeller speed with shallow charge depth providing reduced abrasion of impeller and body liner coverings
