Method for regulating the delivery capacity of a rotor of a separating device of a stirred ball mill, and stirred ball mill for comminuting material to be ground

摘要

The invention relates to a method for regulating the output of a rotor of a separating device of a stirred ball mill for comminuting material to be ground with the aid of grinding balls. The stirred ball mill has a preferably cylindrical, horizontally arranged grinding vessel, at least one stirring unit which is driven by means of a drive, a material inlet, and a fine material outlet. At least the fine material outlet is assigned a separating device with a rotor for retaining the grinding balls. The material to be ground is pumped by means of an external pump via the material inlet into the stirred ball mill. According to the invention, the internal volume of the grinding chamber near the separating device and/or the flow cross section near the separating device can be adjusted on the basis of the throughput of material to be ground through the stirred ball mill, that is to say, in particular, according to a pumping speed of the external pump. The invention further relates to a stirred ball mill.
