Abstract: The invention related to a control system for a mill, particularly a roller grinding mill, comprising a mill control device (11), which is designed to control at least one mill characteristic on the basis of an associated target variable, and a fuzzy-control device (13), which is connected to the mill control device (11) and designed to adjust the target variable of the at least one mill characteristic to be controlled when at least one operating parameter of the mill deviates from a predefined normal range as a function of fuzzy rules that are based on said at least one operating parameter of the mill until the at least one operating parameter of the mill has reached the predefined normal range again. A solution is to be provided, which enables automated optimized mill operation even with changing operating conditions, particularly a mill operation that prevents the “mill rumbling”.

Abstract: In a roller mill (1, 46), in particular a coal mill, comprising a mill housing (2) comprising a rotating grinding table (4) with grinding tools located thereon, in particular grinding rolls (5), a grind material feed (9), a classifier (8), at least one grind material exit (11), at least one sealing gas seal (14, 16, 17, 19) that seals off the mill interior (31) from the outside atmosphere in the area of moving mill elements and a carrier gas feed (12), wherein the roller mill (1, 46) can be operated in pressurized mode, a solution is to be provided that facilitates the use of recirculated stack gas as sealing gas without significantly affecting the mill environment.
