Building a Soil Sifter / Rotary Trommel
Step 1: Building the Mesh Tube. I cut a length of sheet metal to attach to the inside of the wheel rim. This probably helps to support the mesh but you may be able to get away without using it. I cut it 4 inches (100 mm) wide* then carefully removed the burrs with a file.

Rotary Screens
The equipment is installed in the channel at 35° from the horizontal plane, and the sewage flows into from the port of the rotating drum. The water flows out through the grating slit on the side of the drum. The drum screen traps suspended solids and floating objects in the water in the drum. The drum rotates at 5-8r/min speed.

Simulation Conditions. A drum with a diameter of 170 mm and length of 850 mm ( Figure 1) was used in the simulation to investigate the effect of the angle of inclination on the particle mixing dynamics in rotating drums. Four simulations with angles of inclination α = 0° (horizontal), 5°, 10°, and 15° were carried out.
