The linear vibrating screen uses two vibrating motors as vibration sources, and the two vibrating motorsdo synchronous opposite movement,so that the material is forced to do parabolic linear movement on the screen. Materials uniformly enter the screen surface of the vibrating screen form the previous process through the distributing device at the feed port of the linear screen machine, and the materials are forced to pass through the screen in the moving process, so as to achieve classification of different specifications.
