Mineral processing

Sizing is the general term for separation of particles according to their size. The simplest sizing process is screening, or passing the particles to be sized through a screen or number of screens. Screening equipment can include grizzlies, bar screens, wedge wire screens, radial sieves, banana screens, multi deck screens, vibratory screen, fine screens, flip flop
