Document Type and Number:
WIPO Patent Application WO/2014/012792
Kind Code:
A3
Abstract:
The invention relates to a method and a system for comminuting grinding stock using a roller mill in which a grinding dish (1) cooperates with at least two grinding rollers (2, 3) and the grinding stock (5) that is delivered in a mass flow is comminuted between the grinding dish (1) and the grinding roller (2, 3). At least two grinding rollers (2, 3) are driven by independent drive units (6, 7). The power compensation between the drive units (6, 7) of the grinding rollers (2, 3) is regulated so that the power of the drive units (6, 7) is at a predefined ratio relative to one another. According to the invention, the power is regulated by modifying the mass flow of the grinding stock (5) delivered to at least one of the grinding rollers (2, 3). In order to do so, the power compensation regulation device (8) cooperates with at least one control member (11) for modifying the mass flow of the grinding stock (5) delivered to at least one of the grinding rollers (2, 3).
