Abstract

The herein-disclosed vibrating screen pertains to equipment used in the mining industry for a preliminary size-grading of lump material (mineral product). The screen has a material feeder, a sized material conveyer and a working member, all said components being mounted on a common frame. The working member is composed of two solid plates mounted on frame supports and given a oscillating motion from vibrators, whereby the material being handled is classified into size fractions. The plates make up an angle with each other so that an aperture is defined between the bottom edges thereof for the fractions of the material being sized to pass therethrough, while the oversize (plus material) on the plates is caused to move therealong by virtue of vibrating motion performed by the plates, to get onto the conveying device.
