Abstract
A method is described for controlling the grinding of a dispersion of solid particles in a doughy-pasty mass, such as a chocolate mass, on a roller mill line having at least one preceding and one postponed roller mill (1 or 4), of which at east the postponed roller mill (4) is a roll refiner mill with a plurality of rollers (W1-W5). In this arrangement, the outlet roller gap of the preceding roller mill (1) is changed for decreasing or increasing the layer thickness of the mass in the postponed roller mill (4) having at least three rollers. Additionally and besides changing the outlet roller gap of the preceding roller mill (1) a control of the layer thickness of the postponed roller mill (4) is carried out according to a proportional-integral-differential control system. In doing so, the layer thickness can be measured on the postponed roller mill (4) within predetermined limits, with a change-over to the control system of the preceding roller mill (1) taking place upon exceeding these limits due to the difference of the actual thickness to the nominal layer thickness.
