This involves a conceptual problem: Mohs hardness. What is the difference between Mohs hardness and what we usually call hardness? Here we first look at these two different concepts.

Some customers reported that when Raymond Mill processed calcite mineral powder, 325 mesh mineral powder contained a large amount of 10um ultra-fine mineral powder. If 10um ultrafine ore powder can be separated and the output can be expanded, the benefit will be greatly improved.

Practice has proved that when the calcite with the feed size of 25mm is selected for grinding, when the fineness is adjusted to 1250 mesh (10um), the output can reach 450kg / h, and the input power only needs 23KW, which has significantly higher cost performance than the traditional Raymond mill.
