Selection is good or sub ballast drum sieve shaker.
Because the material rolls and rolls in the drum, the material stuck in the sieve can be ejected to prevent the screen from clogging. The principle and structure of roller screen sand machine, drum screen and roller screen are almost the same.
The drum device is inclined to be mounted on the frame. The motor is connected by a reducer and a roller device through a shaft coupling, and the driving roller device rotates around the axis of the motor. When the material enters the cylinder device, due to tilting and rotating drum device, so that the screen material turnover and rolling, the qualified materials (sieve products) is discharged through the discharge port at the bottom of the rear end of the drum, the unqualified materials (sieve products) is discharged through the discharge port of the cylinder tail.
The roller screen is mainly used for separating the finished product from the returned material, and can also realize the classification of finished products and make the finished products even. The combined screen mesh is convenient for maintenance and replacement. The structure is simple, the operation is convenient and the operation is stable.
