Abstract
There is disclosed a process and an apparatus for comminuting solids wherein an attrition-grinding mill includes a grinding chamber having an inlet means enabling a feed slurry of a particulate solid to be comminuted to be introduced into the grinding chamber and an outlet means including a sieve for allowing therethrough a ground product slurry whilst retaining a granular grinding medium within the grinding chamber, the sieve being disposed below the surface of the contents of the grinding chamber and wherein there are first control means associated with the inlet means and/or with the outlet means of the attrition-grinding mill for controlling the relative volume flow rates of said feed slurry and said ground product slurry, and second control means associated with the outlet means of said attrition-grinding mill and responsive to changes in the volume ratio of granular grinding medium to slurry in the grinding chamber for stopping or starting the flow of ground product slurry through said outlet means.
