Solid waste separation trommel screen roller screening machine’s main structure is cylindrical drum, which is inclined and installed on the frame. The geared motor is connected to the drum device through a coupling, the driving drum will rotate around the axis direction. When the materials enters the drum device, due to the tilt and rotation of the drum device, the materials on the screen surface is overturned and rolled so that the fine material is discharged through the discharge port at the bottom of the back end of the drum of Solid waste separation trommel screen roller screening machine, and the coarse material is discharged through the discharge port at the tail of the drum discharge. As the material in the drum devise flip, rolling, so the materials stuck in the sieve can be ejected to prevent the sieve blocking.
