Automatic de-oiling centrifuge
max. 10 m³/h | PERMOLEX-POLAR series
Steimel
The continously operating centrifuge for the recovery of coolants when swarf and grinding sludge are processed.
ADVANTAGES:
- Suitable for swarf of all common metall classes and grinding sludge
- Very low residual moisture achievable
- High wear resistance due to manganese lining
- Continuous and fully automatic operation
- Low maintenance and service cost
- Very high operational reliability
- Short payback period
FUNCTION:
The metal swarf mixed with coolants or grinding sludge are conveyed by means of a suitable controllable conveying device. The metering screw (optional for K41 - K101) in the charging hopper of the centrifuge has the task to feed the materials evenly into the drum. According to the kind of swarf, coolant and continuity of the swarf flow to the centrifuge the use of the metering screw can be dispensed with. For swarf tending to get stuck or to stick (e. g. aluminium) the use of the metering device is basically recommended.
Due to the particular drum design and the effect of the centrifugal force swarf is spun against the inner wall of the centrifugal drum and is then slowly pushed upward within the drum by succeeding swarf. The throughput capacity of the centrifuge and thus the dwell time of the swarf in the drum are determined by controlling the conveying speed of the conveyor.
At the largest drum diameter the coolant passes out of the drum through an exchangeable bar screen into the spinning off area.
The dried swarf is pushed over the upper drum rim. Outside it is spun against an exchangeable manganese rebounding ring. Swarf and coolant are separately led out of the centrifuge.
