Abstract
A stirred ball mill including a grinding container, in which an agitator shaft having grinding elements is arranged, whereby a grinding chamber is formed between the grinding container and the agitator shaft, into which chamber the grinding elements extend and into which at least one inlet duct for grinding material opens and in which a dynamic separation device for grinding bodies is provided, the separation device having recesses for feeding back the grinding bodies, and in which the agitator shaft has at least one recess, which widens the separation device and extends in the axial direction into the grinding chamber for improved distribution of the grinding bodies in the grinding chamber.
Claims22
An agitator ball mill with a grinding container, wherein an agitator shaft provided with grinding elements is disposed, as result of which a grinding chamber is formed between the grinding container and the agitator shaft, in which grinding chamber the grinding elements extend, in which at least one inlet channel for grinding stock emerges and a dynamic separating device for auxiliary grinding bodies is provided, wherein the separating device is provided with recesses for the return of auxiliary grinding bodies, characterised in that the agitator shaft is provided with at least one recess extending the separating device, said recess extending in the axial direction into the grinding chamber.
A method for grinding with an agitator ball mill, wherein grinding stock is supplied via an inlet channel and is conveyed in a grinding chamber formed between an agitator shaft and a grinding container in the direction of a dynamic separating device, wherein auxiliary grinding bodies contained in the grinding stock are transported in the radial direction back into the grinding chamber by means of the separating device characterised in that the auxiliary grinding bodies also flow into the grinding chamber through a section of the agitator shaft that extends the separating device.
An agitator shaft an agitator ball mill, characterised in that the agitator shaft comprises at least one recess extending in the axial direction, said recess being assigned to a dynamic separating device.
