Roller screen is a kind of machinery widely used in sorting technology, mainly used for screening granular materials. The working principle is that through the tilt and rotation of the drum device, the material is turned over and rolled on the screen surface, so as to realize the classification and separation of the material. The main components of the drum screen include motor, reducer, drum device, frame, sealing cover and inlet and outlet ?.
Working principle
The working principle of the drum screen is as follows:
? material into the roller device ? : When the material into the roller device, due to the tilt and rotation of the roller device, the material is turned over and rolled on the screen surface.
? Grading and separation ? : Acceptable material (under screen product) is discharged through the discharge port at the bottom of the rear end of the drum, and unqualified material (over screen product) is discharged through the discharge port at the rear of the drum.
? prevent sieve clogging ? : due to the material in the roller turning and rolling, the material stuck in the sieve can be ejected to prevent the sieve clogging ?.
Application field
Drum screens are widely used in many fields:
? stone yard ? : used for grading large and small stones and separating soil and stone powder.
? gravel farm ? : used for sand and rock separation.
? coal industry ? : used for the separation of lump coal and pulverized coal and coal washing.
? Chemical industry and mineral processing industry ? : used for the classification of large and small mass and the separation of powdery material ?.
The characteristics of the roller screen
? sieve is not easy to clog ? : due to the material turning and rolling, the material stuck in the sieve can be ejected.
? Smooth operation, low noise ?.
? simple structure, convenient maintenance ?.
? screening cylinder can be closed, easy to close dust ?.
? High reliability, less one-time investment ?
? The use of special screen, high screening efficiency, long service life ??.
