Construction, Working and Maintenance of Electric

(e.g. a vibrating screen) to vibrate in a defined direction. As shown in above figure, it is possible to generate circular, elliptic or linear vibratory (oscillatory) movements. If a single unbalance motor (drive) is located at the centre of gravity, it generates a circular vibration (oscillation).

Mechanical screening Wikipedia

Mechanical screening, often just called screening, is the practice of taking granulated ore material and separating it into multiple grades by particle size.. This practice occurs in a variety of industries such as mining and mineral processing, agriculture, pharmaceutical, food, plastics, and recycling.. A method of separating solid particles according to size alone is called screening.
