Description

The vertical roller pre-grinding mill is an ultra-fine crushing and grinding equipment primarily suitable for pre-sand powder preparation processes before crushing mineral materials in metallurgy, building materials, chemical industry, and mining. It can also be used for sand-making or producing premium sand. The mill can process brittle, non-flammable, and non-explosive materials with no corrosive properties, such as limestone, dolomite, calcite, quartz, marble, coal gangue, and granite. These materials should have a Mohs hardness of less than 7, a density between 1.4 and 4.6, and a compressive strength below 260 MPa.
