Ball Mill
Abstract
Ball Mill Solution
For a long time, industries such as ceramics, chemical engineering, cement, geology, mineral resources, and metallurgy have commonly used ball mills to grind raw materials.
Materials mix with the grinding media when the ball mill is operation. They are lifted to a certain height under the action of centrifugal force and the frictional force generated between the grinding media and the inner wall of the cylinder. The falling grinding media freely fall and impact the materials at the bottom, breaking the materials under the effect of gravity.
During the operation of the ball mill, the following issues exist:
Difficult to start: The ball mill contains a large amount of grinding media and which are heavy and require a significant amount of electrical energy to start.
Large starting current: Ball mills are generally started by reducing voltage, and large starting current causes significant impact on both the equipment and the power grid.
Frequent mechanical damage: The belt, shaft, gearbox gears and other components of the ball mill are affected by huge inertia and are prone to damage when adjusting the speed, which affects the operating efficiency of the ball mill.
Solution
The integrated cabinet for ball mill is an inverter controller special developed by our company for ball mill.
It utilizes frequency regulation technology and combine with the working principle of ball mills to modify the drive system of ball mill. This inverter can set different operation modes according to the process requirements of different raw materials, achieving continuous controllable running speed of the ball mill, low speed with large torque, no impact during motor startup, and effectively control of the feedback energy caused by the large inertia of the ball mill.
After install the ball mill inverter all in one machine, the problems such as difficult startup, large starting current, and frequent mechanical damage of the ball mill have been solved.This has resulted in smaller grid fluctuations, and increased the lifespan of the ball mill belt, shaft, and gearbox gear.
