Nine Methods To improve High Energy Ball Milling - Ball Mill. In addition, after the mill is shut down for a very long time, the sluggish-pace transmission device earlier than beginning the principle motor can remove the eccentric load of the steel ball, loosen the consolidation of the steel ball and supplies, ensure protected start, avoid overloading of the air clutch, and play a protective role.

Therefore, the large ball mill usually uses air clutch to assist start-up. During the start-up process, the motor is started up to the rated speed. Then, the ball mill is started through the engagement of the clutch. This study focuses on the dynamic behaviours of a ball mill and the dynamic characteristics of the induction motor.

The mill pinion shall be direct coupled with an air operated clutch to a variable speed, 11,000 volt, 5500 kW, synchronous motor. The drive will be located at the feed end of the mill, on the left hand side when viewed from the feed end.

For ball mills, commonly used synchronous motors equipped with an air clutch or gear, it can be easily circulated by connecting to the main gear mill. The power of these transfer motors is usually considered to be enough to grind and grinding various types of raw materials such as stones, ore, etc., depending on the performance of the ball mill.
