1. Operating Principle of Trommel Screen
Trommel screen mainly consists of drum apparatus, rack, seal cover, motor and reducer. Drum apparatus is inclined mounted on the machine frame. Motor and reducer are connected to the drum apparatus by coupling. Drum apparatus rotates around its shaft.
When fed into the machine, the material overturns and rolls on the screen surface due to the inclination and rotation of drum apparatus, which makes undersize product discharge from the outlet at the bottom of drum, and oversize product discharge from the outlet at the tail of drum. And because of the material overturning and rolling in the drum, the material stuck in the sieve mesh will pop out, to prevent the screen mesh clogging.
