Abstract
A method and apparatus for comminuting minerals and similar materials by vacuum comminution includes an arrangement for introducing the material to the low pressure chamber at a high velocity whereby the rate of change of pressure on the particles of material is greatly increased. The degree of comminution is thereby increased and the effectiveness of the system greatly enhanced.
