What is Cryogenics? Cryogenics is the production of and behavior of materials at very low temperatures. Ultra-cold temperatures change the chemical properties of materials. This has become an area of study for researchers who examine different materials as they transition from gas to liquid to a solid state.

Cryogenic grinding experiments were carried out in a cryogenic ball mill (Retsch Cryomill, Germany). The grinding equipment used in the test was a single-ball mill. The volume of the grinding chamber is 50 ml, the diameter of the grinding ball is 26 mm, and the mass is 63 g. During the grinding process, the grinding chamber was cooled by liquid ...

We manufacture complete grinding lines and product separation lines with the use of cryogenic technology. Cryogenic grinding is used for easily meltable, flexible, ductile and fibrous products where very high fineness of up to 30 µm is required (traditional methods for these products do not achieve fineness values below 300-500 µm). Cryogenic grinding can be used in a safe manner for ...
