Drum filter for cutting


Drum Filter

The Drum Filter is a coolant filtration system that uses a rotating drum-shaped filter mesh to remove particles about 60 μm in size from a liquid coolant. Neither the particle substance nor coolant fluidity can be chosen. Continuous operation for extended periods of time without interruption is possible.


The machine performs an in-tank primary sedimentation treatment on a coolant fluid flowing into the dirty tank. Coolant is forced through the surface of a rotating drum filter immersed in the dirty tank by a differential depth pressure and flows into the clean tank to be fed to the processing machine. A conveyor belt is installed in the dirty tank, and sedimented particles are regularly discharged.
