Pneumatic press for the selection of silicon carbide

Abstract From the Canadian patent

This pneumatic press is provided for the selection of silicon carbide in laminar or radial layers of different qualities, and is based on a horizontal and intermittently movable structure combined with the vertical movement of a pressure wear plate which rests on and presses against the silicon carbide parts or chunks arranged over a fixed screen in a manner that said intermittent movements and vertical pressure grind the chunks over the screen to select, according to layers, the silicon carbide contained in the compound or product forming the chunks. The driving means are pneumatic, the vertical pressure of the plate being exerted through twin shaft pressure jacks which enable tilting of …
