ABSTRACT:
A heavy duty agitator ball mill for continuous grinding and dispersion of material suspended in a liquid has an upright rotor made of aligned rotor ring elements, mounted for rotation within a stator which preferably is also made up of aligned stator ring elements. Rotor and stator form a grinding chamber between them which holds a charge of grinding balls. Agitator members extend into the grinding chamber both from the rotor and from the stator. Both rotor and stator have cooling channels for flow of coolant, bounded in part by ribs formed on rotor and stator and hence promoting heat conduction. Working surfaces are of hard wearing materials as is made possible by the construction. The ring elements are readily replaceable, as are hard inserts of the agitator members.
