Rotary drum screen

Introduction of Rotary Drum Screen:

This series of Screen are always used in processing minerals such as ferrous metals including hematite & magnetite and nonferrous metals including Lead, Zinc, Gold and Silver etc. This machine works in a re-circulating network with Ball mill, which can upgrade the fineness of ferrous and nonferrous metals. Its efficiency is twice as that of Spiral Classifier.

Operating Principle of Rotary Drum Screen:

Screen consists of motor, decelerator, rotor drive, chassis, seal cap, inlet and outlet. Material feeds into the drum, is lifted up by the rotation and aerated as it falls back down. This action is repeated with each revolution along the length of the drum. The finer material passes through the screen openings while the larger material tumbles towards its eventual exit at the rear of the drum.
