A FUNCTION OF THE PERMOLEX-POLAR Centrifuge
PERMOLEX-POLAR K51s with the metering screw
The metal swarf mixed with coolants or grinding sludge are conveyed by means of a suitable controllable conveying device such as hinge conveyors, scraper conveyors or screw conveyors. 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 metering screw can be left out. For swarf tending to get stuck or to stick (e. g. aluminium) the use of the metering screw 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 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.
Through a discharge tube the spun-off coolant gets sideways out of the machine. The dried swarf falls downward out of the centrifuge onto a suitable conveying device or directly into a container placed below.
There has to be a continuous flow of liquid within the flushing device to prevent superfine swarf which is discharged with the coolant to deposit in the spinning off area. Coolant can be added from a container placed behind or e. g. directly from a central coolant supply facility.
Permolex-Polar centrifuges can optionally be equipped with hot-air heating which heats the centrifuge and thus leads to a reduction of the viscosity of the used coolant.
Depending on the kind of swarf and coolant the attainable value of residual moisture can be improved.
