During the experiment, when the material is ground and pulverized, the pulverizing part of the pulverizing instrument can be selected according to the Mohs hardness table. The basic principle is that the pulverizing part is at least 1 grade higher than the Mohs hardness of the material to be pulverized. It is possible to achieve crushing. For example, grinding tablets with a Mohs hardness of 1-2, a variety of optional crushing parts, such as agate stainless steel corundum tungsten carbide.
According to the different properties of the materials, the materials can be divided into hard, medium, hard, brittle, soft, tough, temperature sensitive and other materials. Each grinding and crushing requires different instruments.
I hope that the uploaded reference will help you choose the crushing instrument.
