Abstract
The present invention relates to apparatus for comminuting a material. The apparatus comprises a support (4) which is rotatable about a primary axis, and a grinding vessel (17), defining a grinding chamber, which is mounted on the support (4) for rotation about a secondary axis which is substantially parallel to the primary axis. The grinding vessel (17) is provided with an inlet (34) for a feed suspension of particulate solid material and an outlet (36) for a suspension for a fine product. In the first embodiment the grinding vessel (17) communicates with the outlet (36 ) through a screen (35 ). In the second embodiment, the inlet (34) comprises means for regulating the flow rate of the feed suspension. The invention also relates to a process for comminuting a material in a planetary mill, in which process the material is either ground autogenously or is ground in the presence of a grinding medium consising of particles not larger than 1mm.
