METHOD AND APPARATUS FOR SEPARATING MATERIAL

摘要

An apparatus for separating particles composed of a mixture of particles wit h differing physical and chemical characteristics comprising: a comminutor (201, 202) for reducing the size of the particles; a removal mechanism (7) for removing particles between the feed (3) and the comminutor; a removal mechanism (8) for removin g particles from the comminutor to a size classification apparatus (2); a mechanism (16) for returning the oversized particles back t o the comminutor or discharging them to a reject stream (17); and a magnetic and electric mechanism (figure 9) for separating the particles. A method for separating includes: reducing the size of the particles; removing the particles from comminution; providin g particles to a separation mechanism; separating the particles based on size, density or electric and magnetic properties; and returning the appropriate particles to the comminutor.
