METHOD AND SYSTEM FOR COMMINUTING GRINDING STOCK USING A ROLLER MILL

摘要

The invention relates to a method and an apparatus for comminuting grinding stock with a roller mill, wherein a grinding plate cooperates with at least two grinding rollers and the grinding stock supplied in the mass flow is comminuted between grinding plate and grinding roller. At least two grinding rollers are driven via dedicated drives, wherein a power compensation control is carried out for the drives of the grinding rollers, such that the power of the drives is controlled in a predefined ratio to one another. The power control is then effected by changing the mass flow of the grinding stock supplied to at least one of the grinding rollers.
