Abstract
The apparatus is for shredding and straining thermo plastic and rubber like materials to produce clear polymer pellets separated from oversize foreign materials, more particularly an apparatus provided with a hopper and forcing section adapted to feed hot or cold selected process materials into a shredding or granulating section which is adapted to granulate vulcanized rubber to pellets so small that they cannot harbor oversize materials or contaminates. The granulating section feeds warmed and under high pressure process material to the straining section which features multiple circumferential openings, adjustable in width in 0.0005 inch graduations, which lead off the fine and fluent phase materials and redirect the oversize and less fluent material to a separate discharge port. To avoid plugging the entrances to the circumferential openings of the straining section are composed of multiple plates, one set of which is stationary and secured to the barrel member. The second set of plates, each plate between plates of the first set, is movable in an orbital pattern so that the entrance to the circumferential opening is in continual motion in relation to each other so as to dislodge…
