Ball Mill is mainly used to grind materials in mineral, cement, refractory, chemical industry, etc. Ball Mill has dry and wet ways. When wet Ball Mill works, certain water and other liquid will be added into materials to increase flowability of materials, so the capacity is increased. When dry Ball Mill works, capacity is affected because material flowability is reduced, so absorbing wind device is needed on the outlet of Ball Mill, and then negative pressure is formed in the Ball Mill to increase flowability of material, so the capacity is increased.

Working principle:
When the Ball Mill works, motor and speed reducer transmit torque force to big and small gears of Ball Mill, so the barrel rotates.  When the barrel rotates, Steel balls or other grinding media in the barrel are lifted to a certain height and fall down freely, so materials in the barrel are impacted.  Grinding media mixing with materials impact and grind materials continuously.  The grinding media and materials impact and grind each other when the Ball Mill rotates continuously.  The final product will be discharged from outlet when it meets the request, so the grinding process is finished.  
Features:
1.  Large application range, simple structure and convenient maintenance.
2.  Large capacity and continuous work are very obvious.
3.  Barrel lining and grinding media can apply various abrasive materials.
4.  Installation and adjustment are very convenient and easy to be operated.
