Transmission device: The ball mill is a heavy-duty, low-speed and constant-speed machine. Generally, the transmission device is divided into two forms: edge drive and center drive, including motor, reducer, drive shaft, edge drive gears and V-belts, etc. 4. Feeding and discharging device: The feeding and discharging device of the ball mill is ...

With an increase in ball milling time, DAV decreases from 60.1 to 35.5 µ m. When the ball milling time is 50 min, DAV reaches the minimum value of 35.5 µ m, a 41% decrease compared with the value before ball milling. When the ball milling time exceeds 50 min, DAV fluctuates with a variation of ∼3% (Figure 9 (d) ).

The grinding ceramic ball mill uses different ball mill ceramic liner types according to production needs to meet different needs. The finess of ceramic ball mills depend on the grinding time. The electro-hydraulic machine is auto-coupled and decompressed to reduce the starting current. Its structure is divided into integral and independent.
