REPLACEABLE SHEAR EDGE FOR A STAR-TYPE FEEDER

摘要

In a star feeder, equipment longevity may be enhanced by providing a replaceable shear edge at the downstreammost (in the direction o f rotor rotation) portion of the feeder housing inlet, adjacent the clearance between the rotating pocketed rotor and the housing. One or more plates defining the shear edge may be mounted to the housing. Where the feeder is retrofit, a recess may be formed in the housing to accept and position the o ne or more shear plates. A shear plate may have a number of openings elongated in a dimension intersecting the clearance adjacent the inlet, and the position of the plate shear edge may be adjusted to provide an effectively n ew shear edge when it becomes worn. At least the shear edge portion of the shear plate may be of a hard wear resistant material. A removable protective baffle may be disposed in the inlet.
