History. The mechanical belt drive, using a pulley machine, was first mentioned in the text the Dictionary of Local Expressions by the Han Dynasty philosopher, poet, and politician Yang Xiong (53–18 BC) in 15 BC, used for a quilling machine that wound silk fibers on to bobbins for weavers' shuttles. The belt drive is an essential component of the invention of the spinning wheel.

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.

The paper gasket and conical washer can be omitted on the aftermarket basket,they serve no purpose.The purpose of the conical washer is to take up the slop when the rivets start to stretch and the basket gets sloppy.With bolts,the backing plate is securely bolted to the basket and no clearance should not develop between the basket and backing plate unless the screws come loose.

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.

5. Repair or replace worn parts and loose packing. Check oil to see that viscosity is not too low. Check for excessive contamination or wear. 6. Bleed air and check for leaks. Check to see that oil intake is well below surface of oil in reservoir. Check pump packing and line connections on intake side by pouring hydraulic oil over suspected leak.
