Abstract
A stirring or agitating mill has a grinding vessel partially filled with grinding bodies. The vessel is substantially surrounded by a cooling jacket. A rotationally drivable and internally coolable agitator is disposed in the grinding vessel. The walls of the grinding vessel and/or the agitator have heat-dissipating, gently curving projections therein extending helically or parallel to the direction of the longitudinal axis of the vessel. Means may be present within the agitator to direct the coolant against the inside of the projections.
