Here's a shot of some stainless steel media and ceramic media. The stainless steel must be sparkresistant, nonmagnetic steel in the 300series. Alloys 304 and 316 are the most common stainless steels of this type. Highdensity alumina ceramic media is the type I've heard of most often being used in ball mills.

These forces are generated due to particle movement in the mill jar, the motion of balls and contact zones. The ball milling design significantly depends on the size of mill jar, required particle size distribution of powder and grinding media (balls) [13], [14], [15]. The main purpose of milling process is to obtain required particle size of the powder without any contamination, increasing ...

The water can wash away the fine particles in time to avoid overgrinding. The wet ball mill has a low noise, and low environmental pollution. The wet ball mill has a simple transportation device with less auxiliary equipment, so the investment is about 5%10% lower than that of a dry ball mill. The grinding particle size is fine and uniform.
