Introduction:

Trommel screen is composed of motor, reduction unit, cylindrical drum, screen frame and sealing cover. 

Application:
Trommel screen is applied to compost, chemical, coal, construction, gold mine, plastic, recycling, metallurgy, mineral-selecting, agriculture etc.
 
Working principle:
When material flow towards along the inclined rotating drum,materials jump and roll , the undersized material smaller than the screen apertures passes through the screen wire mesh, while the oversized material passes out at the other end of the drum.

Operation and Maintenance
1. Perform the following maintenance daily.
1) Grease the bearings on the drum wheel shafts and thrust wheels. Use multipurpose bearing grease.
 2) Check the vent screens in each motor. If the screens are clogged, brushed them off.

3) Visually check the gearboxes for leaks.
4) Visually check the screen attachment bolts for tightness.
 
3. Perform the following maintenance every six months.
1) Grease the fittings on each motor. This requires approximately two pumps with a hand held grease gun.
2) Change the gear box oil after the first 250 hours and every six months thereafter. Use 90 wt. gear oil.
3) Grease the cleaning brush bearings on each shaft (if equipped). Use multipurpose bearing grease.
