Grinding medium steel ball milling system and grading

- May 26, 2018-

Grinding medium steel ball is the key equipment for crushing the material after it is used. The ball mill is one of the high-fine grinding machines widely used in industrial production. The ball mill is suitable for grinding various ores and other materials and is widely used. In mineral processing, building materials and chemical industries.

Grinding medium ball is the milling system of the ball mill. During the operation, it will effectively influence the milling effect of the ball mill to a certain extent according to the material of the steel ball and the use method. The ball of the ball mill is the ball mill equipment. Grinding the material medium, through the friction between the ball of the ball mill and the material to produce grinding and stripping effect, the important basic components, especially the precision industrial steel ball plays an important role in the development of the national economy.

Some special steel balls for grinding media balls have been widely used in various fields of the national economy when they are used, and effectively include high-chromium steel balls, high-chromium steel forging, and low-chromium steel balls. Low-chromium steel forging, chrome linings, manganese linings, hammers, multi-alloy steel balls, multi-element alloy linings, various wear-resistant materials. Not only has it promoted the development of the ball mill production industry, but it has also promoted the technological development and technological progress of related industries.

How to determine the grading of grinding media balls

1. Hearing

If the impact of the ball in the ball cage is strong and brittle, it means that the grinding capacity is strong; the sound of the fine grinding bin is weak and boring, indicating that the fine grinding ability is insufficient. At this time, the filling rate of the ball bin can be increased, the average sphere diameter can be reduced, and grinding can be strengthened. ability. On the contrary, it is necessary to reduce the filling rate of the ball cage and increase the average ball diameter.

2. Mill production quality

When the output of the mill is high and the fineness of the product is coarse, it indicates that the one-warehouse crushing capacity is too strong and the last storehouse grinding capacity is insufficient. At this point, most of the large ball segments should be removed and replaced with small ball segments to reduce one position or increase the loading capacity of the terminal positions. The low output and coarse thickness indicate that the load of the grinding body is insufficient and the grinding body should be added; the yield is low. The degree of fineness indicates that there are many small balls, few big balls, and weak impact. At this time, some small balls can be taken out to make up for the ball.
