ABSTRACT:
A pulverizing mill is disclosed, suitable for wet or dry foodstuffs, chemicals, plastics and pharmaceuticals, having a reversible welded multi-bladed rotor which is substantially seamless and crack-free so as not to catch and retain particles of the material being pulverized. The rotor blades are supported parallel to the rotor's central axis in a picket-fence configuration in which blade position are staggered from one rotor segment to the next whereby the entire rotor shaft internal volume is swept by one or more blades during each revolution. The blades are supported at predetermined points which raise the rotor maximum safe operating to achieve a higher output of pulverized product. The mill inlet housing is attached by quick-release toggle fasteners associated with fiber-optic sensing means to prevent mill operation unless the housing is fully secured in one of two proper operating positions. The sensing means is associated with control circuitry which automatically ensures proper rotor rotation with respect to the inlet housing position to prevent blow-back of pulverized material.
