A screen consisting of a cylindrical (sometimes conical) screening surface mounted on a revolving frame for sizing coarse material; it is still common in gravel-washing, coalwashing, and stone-treating plants, but is not widely used in ore dressing.
Industry:Mining
A screen consisting of a number of horizontal rotating shafts, fitted with elements arranged to provide screening apertures.
Industry:Mining
A screen deck comprising wires of wedge-shaped cross section spaced from each other at a fixed dimension; the underflow thus passes through an aperture of increasing cross section.

Industry:Mining
A screen designed to reduce or eliminate clogging of material. It consists of wedgeshaped parallel wires with their wide edge upward. This type of screen is used for dewatering coal on vibrating, shaking, or stationary screens.

Industry:Mining
A screen formed by piano wires stretched tightly, lengthwise, on a frame 2 to 3 ft (0.61 to 0.91 m) wide and 4 to 8 ft (1.2 to 2.4 m) high. The screen is set up at an angle of about 45 degrees and crushed material is fed to it from above. The mesh size varies from about 4 to 16. Because there are no cross wires, and because the taut wires can vibrate, there is less tendency for blinding, but some elongated particles inevitably pass the screen.
