Abstract
A screen for a vibrating material sorting apparatus of the type used to sort material in mining operations and the like has a plurality of rows and columns of trapezoidal apertures formed through it. The apertures are oriented so that the narrowest end first encounters material moving down the screen. The apertures are further tapered in cross section, and flare outwardly from the top surface of the screen to the bottom surface. In addition, each of the apertures slopes at an angle which is selected to be the same as the degree of incline of the screen when it is mounted in a vibrating material sorting apparatus.
