ABSTRACT:
A comminution device is provided which has a rotatable turbine mounted in a housing for causing an air flow through an expansion chamber. Material to be comminuted is carried in an air stream through the expansion chamber where it is rapidly decompressed causing it to explode. The turbine is made of a plurality of air foil blades mounted on a backing plate and is dimensioned in close tolerance to its housing. Exchangable expansion chambers are provided to vary the rate of pressure reduction which affects the size of the communited material. The shaft of the turbine is mounted in oil cooled bearings to increase the life and efficiency of the bearings and turbine blades.
