The ceramic grinding media – this type of the grinding media, as the name suggests, is made of ceramic and used mainly in small-sized mills (about 50 liters) in the chemical and food industries. According to the production method, grinding media (except for the rods of short cylinders) are divided into:
Generally speaking, the higher the density of the medium, the stronger the grinding ability and the higher the grinding efficiency. For example, using zirconia balls in an ultra-fine stirring mill has a difference of more than a few digits in grinding capacity compared with using alumina balls and glass balls.
When choosing grinding media ball, two problems are often neglected: 1. The harder the grinding media ball well is, the better the hardness value is; 2. The density of grinding media ball is also a noticeable problem. As for the …

The choice of grinding media The choice of grinding media will always depend on the material to be ground. You need to assess its granulometry and the grinding process. You also need to look at the relative importance of the wear mechanisms in the process. Is there a risk of abrasion, corrosion or impact? And what are the factors influencing these?
Generally the coarser the feed material the larger and denser the grinding media should be — because larger and heavier media generate greater impact forces. Final particle size also should be considered. The finer the required end particle size the smaller the grinding media should be — because small media make greater surface area ...
Grinding medium is a metallurgical term, the energy carrier in the mill to pulverize the material by its own impact and grinding force. The most commonly used grinding media are ball media and rod media.
The principle of operation of these media mills is the same; all three use what is called the grinding media. These are small, hard spherical particles. A sand mill uses sand, but other mills usually use very small glass beads, ceramic beads, or small metal shots. The media are put into a container that is generally closed.

Schematic drawing of an attrition ball mill. The attrition mill agitator rotates at speeds ranging from 60 rpm for production units to 300 rpm for laboratory units and uses media that range from 3 to 6 mm while ball mills use large grinding media, usually 12 mm or larger, and run at low rotational speeds of 10–50 rpm.
Current ball milling theory suggests that grinding capacity is influenced by the size of balls charged to the mill. In selecting the appropriate ball charge, the first objective is to determine that ball size which will grind the coarse particles most efficiently. This size should be the largest ball size charged to the mill.
Higher density grinding media generally results in faster grinding in a ball mill. An optimum grinding charge for a ball mill may be experimentally determined, however generally the range is from 20% to 50% of the mill volume, or to the center line. Approximately 30-40% of the ball charge will be void space. Ceramic Grinding Balls
