Grinding steel balls is the most important part of the grinder, and it is also a necessary product for grinding. Do you know how to configure the steel balls in the grinder? This article is provided by Changzhou Feige Steel Ball Manufacturing Co., Ltd., and tells you about the specification selection and grinding matching plan of grinding steel balls.

1. Steel ball specifications

Under normal circumstances, the diameter of the steel ball of the ball mill is between Φ20mm~Φ125mm (for example, 40mm and 60mm for small balls, 80mm for medium balls, and 100mm or 120mm for large balls). The diameter of steel balls used in super large ball mills is Φ130mm~Φ150mm. Wait.

2. Steel ball proportioning matters

Under normal circumstances, there is no need to add small balls when the ball mill is grinding, because the reasonable friction between the steel ball and the steel ball, the steel ball and the ore, and the steel ball and the ball mill liner during the normal operation of the ball mill will increase the wear. , Make the big ball mill small and medium ball mill into small balls.

The proportion of steel balls of different sizes is also different, but when the ball mill is used for the first time, three kinds of balls, large, medium, and small are required, and the first addition should be based on 80% of the maximum ball capacity given by the manufacturer. Add, because after the ball mill is installed, the large and small gears of the ball mill need to be meshed, and the processing capacity must be gradually increased. After the ball mill runs normally for two or three days, check the meshing of the large and small gears. The remaining 20% steel balls.

3. Steel ball grading scheme

Formulate the grading plan of the ball mill steel balls, usually starting from the first bin (ie, coarse crushing bin). For multi-chamber mills, the ball grading in the first chamber is particularly important. According to the general cross-gradation principle, the smallest ball diameter in the previous chamber determines the largest ball diameter in the next chamber, and so on. One warehouse actually dominates the grading of other warehouses.

At present, there are two representative grading methods for the first chamber of the ball mill: one is the most common multi-stage grading method, which involves dividing the balls into several sizes to optimize grinding efficiency and reduce energy consumption. The other is the two-stage grading method, which simplifies the process by using only two different sizes of balls, making it easier to manage while still achieving effective grinding results.
