Senwei vibration specializing in the production: shaker / straight-line screen / vibration platform 
 The drum screen structure and working principle: drum screen the main motor, reducer, drum units, racks, closures, and out of discharge port. The roller device tilt installed in the rack. Motor through the reducer and the roller device connected through the coupling with the drive roller device around its axis of rotation. When the material into the roller device, tilt and rotation of the roller device, flipping and rolling of the screen surface materials, qualified material (sieve) discharged the drum cylindrical sieve, conforming material (sieve products) by the roller end of the discharge. Materials can be pop-up card in the sieve material within the drum of the flip, scroll, and to prevent mesh clogging. Drum screen sand machine, drum screening machine drum sieve principle of construction is almost the same, there are differences in the awareness and called it. 
 The drum sieve main features: a sieve is not easy to block. Two smooth operation, low noise. 3 simple structure and easy maintenance. Screening tube may be sealed, easy sealed collecting. 5 machine reliability, less one-time investment. 
 A sieve difficult to plug. 
 Two smooth operation, low noise. 
 3 simple structure and easy maintenance. 
 Screening tube may be sealed, easy sealed collecting. 
 5 machine reliability, less one-time investment. 
 6 using a special screen, high efficiency, long service life. 
 The scope of drum sieve: large gravel quarry for grading. Isolated from soil and powder. Second, the gravel field with sand separation. Third, the coal industry for the separation of lump coal and pulverized coal and coal washing (coal washing machinery components). Fourth, the chemical industry, mineral processing industry for the size of lumps classification and separation of the powdered substance.
