Mechanical screening - WikipediaStratification - This phenomenon occurs as vibration is passed through a bed of material. This causes coarse (larger) material to rise and finer (smaller) material to descend within the bed. The material in contact with screen cloth either falls through a slot or blinds the slot or contacts the cloth material and is thrown from the.coarse vibrating screening theory,coarse vibrating screening theory,Principles of Screening and Sizing - 911 MetallurgistThe vibrating screen capacity is determined: • Using a standard .
