MACHINE FOR USE IN THE MANUFACTURE OF GRINDING WHEELS

摘要

A machine with a work table in which a mold cavity is formed. A shuttle hopper discharges grinding wheel mix into this cavity while rotating. A deflecting blade below the shuttle hopper distributes the mix uniformly in the cavity and smooths the upper surface level with the top of the mold edge. The blade is generally spiral in shape, the inner portion thereof expanding from the axis of rotation so as to intersect radii at 55 DEG .
