Application of high efficiency Ball Mill

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. Ball mills can be classified into two main types namely, tabular type and flowing type, depending on the different forms of the discharged material.

Working Principle of Ball mill
Henan Hongji 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.

Features of Ball Mill
1.The ball mill is an efficient grinding tool which is capable of grinding various types of material into fine powder.
2. The ball mill crushes and grinds many kinds of ores and rocks during mining. It is also used for mine selection.
3. Ball mills are widely used in the mining industry, construction industry and chemical industry.
4. Two grinding techniques that can be used are the dry-type grinding and the wet-type grinding.
