The Pneumatic Clutch for Ball Mill is specifically designed for heavy-duty grinding equipment and industrial transmission systems. It provides reliable engagement, disengagement, and torque transmission for ball mills operating under high load and demanding conditions.
This clutch typically adopts a VC-type structure, which offers superior performance compared to traditional CB-type designs. The friction plates are mounted on aluminum shoes and connected to side plates through torque bars, significantly improving torque capacity and heat dissipation.
It is suitable for semi-autogenous (SAG) mills and fully automatic ball mills, making it an ideal solution for mining, cement, and mineral processing industries.
Key Features
- High torque transmission for heavy-duty applications
- Smooth engagement and disengagement
- Excellent heat dissipation performance
- Suitable for low-speed, high-load start-up conditions
- Durable structure with long service life
- Reduced maintenance requirements
Working Principle
The clutch operates using pneumatic actuation:
- Compressed air is supplied into the air tube
- The air tube expands outward
- Friction shoes press against the drum surface
- Torque is transmitted efficiently
When the air pressure is released, the clutch disengages automatically.
