Types of grinding media

Grinding media can be divided into several types according to different aspects

- By geometric shape:

+ Balls

+ Short cylinder

+ Steel bar (round billet)

+ Truncated cones (cylpebs,...)

- By material

+ Steel grinding media: carbon steel was employed as the raw material for the manufacture, which was doped with various chemical components to impart qualities such as hardness and strength to the grinding media.

+ Cast iron grinding media

+ Ceramic grinding media

Today, grinding media with the shape of a ball or a truncated cone are widely used in industry.

Grinding balls: This grinding media type is constructed of steel and cast iron. Methods of manufacture include helical rolling of round billet, molding, and stamping. Stamped ball makers have recently lost market importance because this technology is highly energy expensive, resulting in higher-end product costs. Molding is a second approach for lowering the cost of final product production. Essentially, it is a cast iron ball. This method of producing grinding balls is very costly. A considerable percentage of "waste" in production affects the cost of the finished product and energy usage. Today, the most competitive steel grinding ball production process is the helical rolling of round billet. For suitably low energy consumption during production, the amount of "waste" should be less than 1-1.5% of the total volume of raw material.

Cylpebs: This type of grinding media is created by the casting and rolling process. Rolled cylpebs are uncommon in the grinding media market. This is due to the high production costs and inferior milling quality that result in this type of grinding media. In the majority of situations, cylpebs are cast from "gray" and "white" iron. It should be mentioned that depending on the cast iron type utilized in the production of cylpebs, this form of grinding medium has a number of disadvantages. For example, "gray" cast iron cylpebs are soft enough to enhance the specific consumption of grinding medium in the grinding process. The high cost of the chemical components that comprise "white" cast iron causes Cylpebs' manufacturing of "white" cast iron to be exceedingly expensive.
