Roller vibrating screen for automatic screening of garbage sawdust sand and gravel

working principle:

The stone drum screen is composed of five parts: hexagonal drum, frame, funnel, reducer and motor. After the crushed stone enters the drum, on the one hand, it is screened with the rotation of the drum, and the material is screened by the centrifugal force of the drum rotation and the jigging effect. On the one hand, the stone with large particle size flows forward along the slope of the drum, and is gradually screened out through screens with different mesh sizes. Small stones fall into their respective funnels after being screened out, and then are transported out manually or sent by gravity to the finished product stack. It has simple and reliable structure, stable operation, good sealing, no pollution, low noise, fast screen change, fine classification, large sorting proportion, high output, accurate sorting, low failure rate, convenient maintenance and other advantages, and is especially suitable for the graded use of sand and gravel yards.

Main features:

one Simple structure, low failure rate and low one-time investment;

two Convenient installation and maintenance; The screen hole is not easy to block, easy to maintain, and low labor intensity;

three Stable operation and low noise;

four Good environment, with protective cover, easy to close and collect dust, effectively preventing dust and particle dispersion;

five Good screening efficiency and long service life;

six Strong adaptability: the screen adopts the replaceable chip connection mode, which is easy to replace or replace the screen with different mesh sizes after wear, and is suitable for screening different materials;
