The linear screen (linear vibrating screen) uses the excitation of the vibrating motor as the vibration source to make the materials be thrown up on the screen and move forward in a straight line at the same time. The materials evenly enter the feed inlet of the screening machine from the feeder, and several specifications of above and below the screen are generated through the multi-layer screen and discharged from their respective outlets. It has the advantages of low energy consumption, high output, simple structure, easy maintenance, fully enclosed structure, no dust overflow and automatic discharge, which is more suitable for assembly line operation Scope of use The screening and grading of powdery and granular materials are widely used in coal, hydropower, mining, building materials, chemical industry, plastics, abrasives, medicine, grain, carbon, chemical fertilizer and other industries
