Brief Introduction of Ball Mill

The ball mill is the key equipment for crushing after the material is crushed. It is a kind of equipment in which a certain number of steel balls are loaded as grinding media.

The ball mill is widely used in production industries such as cement, silicate products, new building materials, refractory materials, fertilizers, ferrous and non-ferrous metal beneficiation, and glass ceramics, for dry or wet grinding of various ores and other grindable materials. The ball mill is suitable for grinding various ores and other materials. It is widely used in mineral processing, building materials and chemical industries. It can be divided into dry and wet grinding methods. According to the different discharge methods, it can be divided into grid type and overflow type.

The ball mill adopts a horizontal cylindrical rotating device, and the outer edge of the gear drive. The material enters the first silo of the mill evenly from the feeding device through the feeding hollow shaft. The bin has a stepped lining or corrugated lining. It contains steel balls of different specifications. The rotation of the cylinder produces centrifugal force to bring the steel ball to a certain height. After falling down, it will hit and grind the material. After the material reaches rough grinding in the first silo, it enters the second silo through a single-layer partition board. The silo is set with a flat lining plate and has steel balls inside to grind the material further. The powder is discharged through the discharge grate plate to complete the grinding operation.

The main function of the steel ball in the ball mill is to crush and crush the materials, and also play a certain grinding role. Therefore, the purpose of grading steel balls is to meet the requirements of these two aspects. The quality of the crushing effect directly affects the grinding efficiency, and ultimately affects the output of the ball mill; the parameters that determine the fineness of the ball mill, such as the size of the ball mill, mainly include the size of the steel ball, the number of ball diameter series, and the proportion of various specifications of the ball.

The ball mills are mainly classified according to mechanical methods, including cement ball mills, tube ball mills, ultra-fine laminating mills, cone ball mills, ceramic ball mills, intermittent ball mills, overflow ball mills, lattice ball mills, wind discharge ball mills, double warehouse ball mills, etc. .
