Main Structure And Working Principle of Ball Mill

Ball Mill is a crucial equipment for grinding after materials are crushed, it is an efficient tool for grinding various materials into powder, it is Widely used for the cement, the silicate product, new type building material, fire-resistant material,chemical fertilizer, black and non-ferrous metal, glass, ceramics.

Ball Mill Structure:

Ball mill is composed by feeding part, discharging part, rotation part and driving part (reducer, small driving gear, electric motor and electric controller) and so on. The hollow axis of ball mill adopts the cast steel, and the lining can be replaced. The big rotary gear is forged from cast rolling gears.The barrel body of the ball mill is inlaid with wearable plates.

Working Principle:

This Ball Mill, a horizontal type and tubular running, has two warehouses. It runs along the outside gear. Materials spirally and evenly enter the first warehouse along the input hollow axis by input devices. In the warehouse, there is a ladder scale board or ripple scale board. Steel balls of different specifications are installed in the scale board of the ball mill. When the barrel body rotates, centrifugal force is produced. At the same time, the steel balls are carried to some height and then fall to grind and strike the material. After being grinded coarsely in the first warehouse, the material then enters into the second warehouse of the ball mill for regrinding. In the end, the powder produced by the Ball mill is discharged by output material board.

After the material entering the hollow axis by the feeder, the material will be taken evenly and spirally into the first warehouse, where there is the ladder liner or the ripple liner with the different steel balls. When the tube structure revolving produces the centrifugal force, the steel balls will be carried higher to some extent, and then fall down to strike and grind the material. After grinned generally in the first warehouse of ball mill, the material then will be taken into the second warehouse, in which there is the flat liner, the material will be regrind and then be discharged through the discharge grate liner.

This is the structure and whole working process of ball mill.
