Grinding
The material to be ground is subjected to compressive stress between the grinding table and the grinding rollers, and is comminuted in the process. They are suitable for brittle/elastic grinding materials; the fineness level of the end product is between 20 µm and 100 µm. Popular applications include soft to medium-hard mineral raw materials.
