Function requirements of ball mill balls and media for grinding materials

- Jun 05, 2018-

During the operation of the ball of the ball mill, the medium of the grinding material of the ball mill equipment is mainly through the grinding and stripping effect caused by the friction between the balls of the ball mill and the collision of the materials, and important basic parts and components. In particular, precision industrial steel balls play an important role in the development of the national economy. Widely used in cement plants, power plants and so on. High-low chromium multi-element alloy steel ball, high-low chromium multi-element alloy casting and forging.

Ball mill ball in some special conditions, to a certain extent, often need special steel balls, to a certain extent, to complete the functions required by its different environments, in fact, some special steel balls have been widely used in the national economy In the field, include high-chromium steel balls, high-chromium steel forging, low-chromium steel balls, low-chromium steel forging, chromium series linings, manganese series linings, hammers, multi-alloy steel balls, multi-element alloy linings, and various types of resistance Grinding material.

Ball mill balls are, to a certain extent, the key equipment for crushing the material after it has been broken. To a certain extent, it is one of the high-precision mill equipments widely used in industrial production. There are many types of ball mill operations, such as horizontal type. Ball mills, ball mill bushes, energy-saving ball mills, overflow ball mills, ceramic ball mills, lattice ball mills, etc. The ball mill is suitable for grinding a variety of ores and other materials and is widely used in mineral processing, building materials and chemical industries. It can be divided into dry and wet grinding methods. According to different ways of ore discharge, it can be divided into grid type and overflow type.

When the ball mill ball is used, the output of the ball is not only affected by the ball load, but also to a certain extent related to the diameter of the steel ball. To a certain extent, a certain ball diameter and different ball diameters are required to maintain a certain degree. The relationship between the ratio, the size of the ball diameter in the general cylinder range of 25-60mm. If the cylinders are all large-diameter balls, the impact force is greater, and it is beneficial to crushing large coal. However, due to the large gap between the balls and the ball, the relative surface area is small, and the extrusion and milling effects are weakened. Both the output and pulverized coal fineness are unfavorable.


There are too many small-diameter steel balls in the cylinder of the ball mill balls, so the impact force is small to a certain extent. This will make the output of the coal mills drop to a certain extent. At the same time, because the surface area of the steel balls is relatively increased, the balls will be made into balls. As wear increases, power consumption of grinding coal rises.
