Industrial Solutions polysius ball mills

Single-compartment mills are of a similar design to air-swept mills, but the material is discharged mechanically by a discharge diaphragm. These mills are well-suited for finer feed materials. They are used for secondary grinding downstream of a primary grinding unit or in a combi-grinding system with a polycom ® high-pressure grinding roll.
