Abstract: A material bed roller mill for comminution of grain in a material bed. The material bed roller mill comprises rollers, at least one feed opening, a draw-in region between the rollers, a grinding gap between the rollers and at least one delivery opening. The material bed roller is configured, during operation, to produce a material bed in the draw-in region and to draw grain from a surplus thereof by a filled material duct or hopper. A specific grinding force of the material bed roller mill can be set in such a way that grain is heated, during the grinding operation, by less than 30° C., preferably by less than 15° C., to the temperature of the grain before the respective grinding.

Abstract: A grinding arrangement for producing flour from cereal grain has at least one grinding mechanism designed as a stock-bed roller mill. The grinding mechanism has at least one feed opening and at least one dispensing opening. The grinding arrangement has at least one separating stage for separating ground products into finer ground product and coarser ground product, and returns at least some of the coarser ground product into the feed opening of the grinding mechanism.

Abstract: The apparatus according to the invention relates to a grinding arrangement (1) for producing flour from cereal, the latter in particular being bread wheat, durum wheat, maize or buck wheat. The grinding arrangement is characterized by at least one grinding mechanism (2) which is designed in particular as a stock-bed roller mill (16). The grinding mechanism has at least one feed opening (3) and at least one dispensing opening (4). The grinding arrangement comprises at least one separating stage (5) for separating ground products into finer ground product and coarser ground product, and a return arrangement (8) for returning at least some of the coarser ground product into the feed opening of the grinding mechanism.

Abstract: An agitator mill for treating a liquid containing material particles for example for dispersing paint pigment in a mixture of solvent and binder basically comprises a milling vessel containing freely movable milling bodies and with an inlet and outlet for said liquid, stirrer mechanism within the milling vessel and an electric stirrer motor for driving the stirrer mechanism. The mill features, for the purpose of obtaining optimum operating efficiency, a control circuit which regulates the stirrer motor current to a constant value by adjustment of a pump supplying the liquid to the milling vessel and/or a volume controller for controlling the volume of milling bodies within the milling vessel or the volume of the milling vessel and a temperature control circuit which controls the operating temperature in the milling vessel to lie at a constant value. Various variants and control possibilities including the use of a computer are set forth together with methods of controlling the agitator mill.
