IMPROVEMENTS IN CENTRIFUGAL GRINDING MILLS

摘要

Improvements in centrifugal grinding mills comprising: a grinding chamber (4) of substantially circular cross-section with respect to an axis of symmetry (2) which moves and is constrained to generate a conical surface of revolution about a relatively stationary axis (1); support means (7) for supporting the grinding chamber; a feed passage (5) in communication with the grinding chamber; driving means (11) for driving the grinding chamber about said relatively stationary axis; and constraint means (12, 14) for determining the form of motion of said axis of symmetry of the grinding chamber.
