What is a ball mill? Features and working principles of ball mill

2022-05-31 14:40:42

Product Description

Due to the low rotational speed, ball mills are ideal for grinding hard and abrasive materials such as quartz and zircon sand, as well as for grinding soft minerals such as calcium carbonate and kaolin. Widely used in mineral processing, building materials, chemical and other industries.

The grinding mechanism occurs with minimal impact and wear energy, so ball mills are good for producing large quantities of high-quality powders. They can be divided into dry grinding and wet grinding methods. Different discharge methods can be divided into grid type and overflow type.

What is a ball mill Features and working principles of ball

Product Feature

The Ball mill is mainly used for secondary crushing of mining ore, Dry ball mill is the key equipment for Grinding materials after crushing.


The working principle of ball mill

Ball mills work by using balls to grind materials. Materials such as iron ore and ceramics are added to the ball mill. Next, the ball mill is activated so that it rotates — either on its vertical or horizontal axis. As the ball bill rotates, the balls bounce around while striking the enclosed material. The force of these strikes helps to grind the material into a finer, less-coarse medium.
