Rotary Sand Screening Machine (Cylindrical Trommel Screen)

This is a 3D CAD model of a Rotary Sand Screening Machine (Cylindrical Trommel Screen) designed in SOLIDWORKS. The machine is used to separate sand, soil, gravel, and other granular materials by particle size using a rotating cylindrical mesh. The assembly includes the trommel drum, supporting frame, rollers, shafts, bearings, hopper, discharge outlets, and belt-driven power transmission system. This model is suitable for mechanical design studies, manufacturing drawings, project development, and educational purposes.
