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, [4] bar screens, wedge wire screens, radial sieves, banana screens, multi-deck screens, vibratory screen, fine screens, flip flop screens, and wire mesh screens.

The first step to achieving mass flow is to ensure that the converging walls are steep enough, and have friction low enough, to allow the bulk materials to slide along them. This is accomplished by first testing the material to measure wall friction, and then calculating the minimum hopper angle that will allow mass flow. Hopper angle for mass flow
