Continuous Crushers

Continuous Crushers

Continuous Crushers are Roller Crushers that are characterized by a continuous rotary circumference formed by a plurality of plates along the orbit of rotation described by the crusher impeller blades and extending from each impeller blade to each next blade. The impeller blades are secured to the crusher body by a combination wedge means comprising a truncated, thick walled cylinder and a polyhedron with matching inclined planes. Both the plates and the impeller blades are symmetrical in shape, and combination wedge means is located at a point of least stress to each impeller blade.

Design

A rotary impact crusher impeller having a drive shaft, two spaced shaft plates mounted on the shaft and extending radially outwardly of the shaft, impeller blade recess in the periphery of each shaft plate, a plurality of impeller blades spaced around the periphery of each shaft plate with each blade extending through an impeller blade recess in each shaft plate and the longitudinal axis of the blade generally parallel to the axis of the rotary shaft, wherein the improvement comprises a plurality of peripheral plates each having a radial inner surface, each peripheral plate overlying the opening between two adjacent impeller blades and the spaced shaft plates, the radial inner surfaces of the peripheral plates resting upon the outer peripheral surfaces of the shaft plates between the adjacent impeller blades, a mounting member on the radial inner surface of each peripheral plate and removable mounting means engageable with the mounting members for securing the peripheral plates to the impeller against centrifugal forces wherein the impeller blades and peripheral plates form an essentially continuous surface extending around the impeller for preventing work from falling into the impeller interior during low-speed crushing.
