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.
