Different Approaches to Grinding Abrasive Materials - The calculation of roll torque and roll separating force ...

The invention relates to the comminution of brittle material for grinding in a material bed roll mill with two grinding rolls, in which the material for grinding is comminuted between the cylindrical surfaces of the grinding rolls by the application of a grinding force.Rod mill is similar to ball mills but it uses long rods for grinding media. Autogenous mill is a self-grinding mill which is used in breakage of larger rocks. SAG (Semi-Autogenous Grinding) mill is an autogenous mill which uses grinding balls, it is similar to …

Answer: When the Raymond mill is running, the material to be processed enters the grinding chamber of the main machine and Raymond grinds the glass. Due to centrifugal force when the main shaft rotates, the grinding roller oscillates and the …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. Air-swept mills are single-compartment mills.
