The drying and dispersing modified rotor mill is a very efficient mechanical mill with multiple rotors on its vertical shaft. Multi-layer grinding cutter head, strong shearing force and breaking power, can be connected to hot air source for multiple purposes, and realize the functions of drying, dispersing and modifying at the same time.
Drying Dispersing. Dry milling has requirements for water content of material (usually 4%). Materials with high water content need to be properly dried before milling or reduce the moisture content to a certain limit before milling. The powder products involved in food, medicine, fertilizer, pesticide and other industries will inevitably ...
