Explore the structure and operating principles of ball mills

Ball mills are widely and popularly used in the industries of mineral exploitation, stone mining, cement, ore, chemicals, and construction materials. To operate safely and prevent occupational accidents, it is necessary to know the structure and operating principles of this ball mill.

The ball mill consists of a rotating barrel containing steel balls of different sizes inside, the rotating action of the barrel is through external gear transmission.

The ball mill receives materials through the spiral shaft into the first warehouse of the ball mill, in this warehouse there is a stepped cone lining plate or a corrugated cone lining, inside there are steel balls of all different sizes. . (Photo: The Nile)

When the ball mill moves and generates centrifugal force, it brings the steel ball up to a certain height and then falls down, smashing hard to crush the material in the grinding chamber. (Photo: Ximanghoangmai)

Then the raw crushed material in the first warehouse passes through the separate floor warehouse partition into the second warehouse, in this warehouse there is a cone liner and steel ball, grinding the material again and the powdered material through the removable unloading plate.

The material is taken out by the cyclone system to finish the grinding process of the ball mill and goes through the steps in the ore crushing line afterwards.

To avoid tragic labor accidents, when maintaining or repairing, it is necessary to completely disconnect the power source, post warnings and have someone on duty to ensure safety in all cases.
