Aug 20, 2014 There are the simplest of vibrating screens where they have a single shaft with an eccentric mass that rotates to induce vibration. The screen frame is supported on springs to allow it to move freely in a circular motion. The screens have to be inclined as these machines rely on gravity to convey oversized material along the screen.
These rugged conveyors and screens move high volumes of material with low horsepower requirements, leveling and orienting material as it is conveyed, reducing surges to downstream equipment. WSM Vibrating Screens/Conveyors are available in a variety of configurations and sized to fit any application. Pan sizes range from 12- 72 wide and lengths up to 150 feet.

Working Principle of YK Vibrating Screen. When the eccentric vibrating screen works, the eccentric shaft rotates constantly. The screen is rising when the eccentric arm moves up, the materials on the screen being thrown around and loose. The screen is falling when the eccentric arm moves down, the thrown materials falling down to the screen.
