How to decide on ball mill grinding media?
Steel balls are one of the most widely used grinding media in cement ball mills, their diameters can range from 20mm to 150mm according to different grinding requirements. In a cement ball mill, generally, φ50100mm steel balls are used in the coarse grinding chamber, φ2050mm steel balls are used in the fine grinding chamber. 2. Short Cylinders.
Ball mill: A rotating cylinder filled with steel balls that grinds the material by impact and attrition. Rod mill: Similar to a ball mill but uses long rods for grinding media that grinds the ...

Automatic and programmable grinding, clockwise and counterclockwise with timing
These two methods can effectively reduce the energy consumption of ball mill. 2. Reduce the feed particle size. The larger the grinding particle size of the ball mill, the greater the work done by ...
Wear of grinding media. One of the major problems regarding the use of ball mills is to balance the size distribution of grinding media into the mill, which is determined by the speed of consumption and rate of replacement [3], as the wear of the grinding balls requires their substitution at intervals.
More balls with small size results in fine powder. As a thumb rule powder to be milled should be taken as 25% of total ball weight. If the quantity of charge is very less then milling balls will ...
Rubber is usually used for smaller ball mills as it is more durable and able to withstand the wear and tear caused by grinding media. Steel is often used for larger ball mills as it is able to ...

A ball mill is a form of grinder that is used to blend or grind materials for use. It is a cylindrical device mainly for grinding material such as iron ores, ceramic raw materials, glass, steel, etc. The ball mill works on impact and attrition principle. Its impact is the size reduction given that the balls drop from almost the top of the shell.

The initial ratio of grading ball was 30 mm: 40 mm: 50 mm: 70 mm = 30: 20: 30: 20. It should be noted that the diameter of instrumented grinding media is 70 mm. Rotation speed of cement ball mill was set to 80%. The grinding time was 10 min for each experiment. The grinding experiments were carried out according to Table 1.
The larger the diameter, the larger the product particle size and the higher the yield; conversely, the smaller the particle size, the smaller the product particle size and the lower the yield. In actual production, it is generally determined by the feed size and the required product fineness.
