The Vibrating screen moves in line. It drives the synchronization and reverses Vibrating Exciter to produce the vibrating power. The vibrating power forces the screen to make the screen cloth move vertically and throws up the materials that on the screen cloth, at the same time the materials move forward in line. It cycles and makes materials sieve. It is widely used for shaped and granule materials sieving and classification in the industry of mining, building materials, chemical industry, metallurgy, coal, fireproof and light industry. It has advantages of good performance, low noise, low consumption, steady Vibration, simple operation and high efficiency in sieving.
