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 (20 1, 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 removing particles from the comminutor to a size classification apparatus (2); a mechanism (16) for returning the oversized particles back to the comminutor or discharging them to a reject stream (17) ; and a magnetic and electric mechanism (figure 9) for separating the particle s. A method for separating includes: reducing the size of the particles; removi ng the particles from comminution; providing particles to a separation mechanis m; separating the particles based on size, density or electric and magnetic properties; and returning the appropriate particles to the comminutor.
