Technical Drawings for Trommel Screen

2D Technical Drawing, Technical Drawing for a Trommel Screen About the machine The trommel screen, also known as a rotary screen, is a mechanical screening machine used to separate materials by particle size , mainly used in the mineral and solid-waste sorting industries. Specifications Material- Coal Feeding size - ≤50 Capacity (t/h) - 30-100 Screen Panel (mm) - 1200X4000 Cylinder Inclination (°) – 6 Output sizes • Duff and Grains - 0-10 mm • Peas - 10=30mm • Nuts - 30-50mm Power (kW)- 5.5 Overall size - 5500X1680X2480 Overall Size (mm Working Principle Trommel screen consists of Motor, Gear, Screen Plates, Supporting Frame, Inlet & Oulet. The trommel drum cylinder is tilted on the rack. The motor is driven by the reducer to rotate the drum unit around its axis. After the material enters the drum device, due to the tilting and rotation of the drum device, the material on the screen surface is flipped and rolled, agglomerated materials crushing, and meanwhile the materials blocked in the screen mesh can be ejected to prevent the sieve hole from blocking. So that the qualified material (the product under the screen) is discharged through the discharge port at the bottom of the trommel screen, and the unqualified material(the product on the screen) is discharged through the discharge port at the tail of the trommel screen.
