Abstract
A mica plate delaminator has a delaminating cylindrical chamber with a flat disk mounted on a drive shaft at a 65 degree angle to the shaft. A screw feeder feeds material from a hopper into the delaminating chamber and the disc is rotated at 600-1200 rpm to force the mica back and forth over itself and the clearance between the disc and the housing to a discharge, delaminating the mica plates to small flakes.
