Abstract

Undersize and oversize particles are separated by means of a continuous screen cloth (12) that has a horizontal opera­ tive separating region. Material is fed onto the cloth from a feedbox at one end of the operative separating region. There are three rows of sprays (36, 40 and 42) located at spaced po­ sitions underneath the cloth in the operative separating region. These sprays dislodge oversize particles that block the aper­ tures of the cloth and fluidise the material, allowing undersize particles to pass through the apertures.
