Copper ball mill Brief Introduction
A ball mill is an efficient tool for grinding various kinds of materials into fine powder. They are generally used to grind material which is 1/4 inch or smaller, down to a particle size of 20 to 75 microns. For the ball mills to be efficient, the grinding has to be done in a closed system with the oversize material being continuously re-circulated into the cylindrical barrel for reduction. Various classifiers such as screens, spiral classifiers, cyclones and air classifiers are used for classifying the discharge from ball mills.
Ball mills are largely used in the mining industry for the grinding and selection of material. They are also used in the construction industry (for building material), chemical industry, among others. The grinding may be carried out either through the dry process or the wet process.
Copper ball mill Working Principle
A ball mill has rotating cylinder that is mounted horizontally and is controlled (driven) by an outer gearwheel. A quill shaft uniformly transfers the material to the grinding chamber. The chamber consists of different specifications of steel balls such as ladder linear and ripple linear.
Rotation of the horizontal cylinder creates centrifugal forces which elevates the balls to a certain height where they fall back, grinding the materials. The ground material is then discharged.
Model | Rotation speed (r/min) | Ball load (t) | Feeding size (mm) | Output size (mm) | Capacity (t/h) | Power (kw) | Weight (t) |
900×1800 | 36-38 | 1.5 | ≤20 | 0.075-0.89 | 0.65-2 | 18.5 | 4.6 |
