Device for separating, by pressing and extrusion, the two materials making up certain industrial waste, with a view to recovering at least one of them.

摘要

Sepn. of two component industrial waste by pressing and extrusion uses two parallel axially superimposed cylinders (2, 3) able to be maintained in position separated are from the other in a given-position. One is driven at variable speed. Cylinders consists of a robust empty framework (22, 23) covered by a thin ferrule (23, 33) pierced by regularly spaced poles (24, 34). A vibrating conveyor (50) feed, waste between the cylinders, downstream of which there are horizontal scraper blades (25, 35) in contact with the cylinders to remove externally attached waste. One side (28,30) of each cylinder is open and inside each cylinder is an inclined ellipsoidal shaped wall (6, 7) the edge of which scraper the inside wall of the cylinder, removes material and drives it to the open cylinder side.
