PROCESS AND DEVICE FOR MECHANICALLY REMOVING THE SURFACE OF LUMPED GOODS

摘要

According to a process for mechanically removing the surface of lumped goods, these lumped goods are accelerated and projected by a mechanically impulse from a bottom (14, 16) against a processing surface (18, 20), then return to the bottom. The process is repeated along the conveying path of the lumped goods and/or for a determined length of time, until the desired wearing out of the surface is achieved.
