Products - Single systems - Chip conveyors - Return pumping station RKR

Application

Provided return pumping stations are conveyor systems for placement on single machines and transfer lines. They are used for the unmanned transport of chips and cooling lubricant from the processing machine to a separator/filter. Cooling lubricants and chips that result during the cutting of materials such as steel, cast iron or aluminium are particularly suitable.

Properties	Benefits
Fully automatic cooling lubricant and chip conveyance	No manual intervention required
Variable height	Adaptation to customer conveyors
Chip reducer can be retrofitted	Adaptation to expanded requirements
Maintenance areas outside the machine	Easy accessibility
As an option with transport rollers	High mobility

Combination options

For further requirements, we can combine return pumping stations provided on request with

Chip reducers to achieve pumpable chips
Chip conveyors for discharging chips from the machine
Centralised separator/filter systems for cleaning the cooling lubricant and supplying the machines
Suction stations for further transport of the chips to the central system and the container station
Centrifuges and briquetting systems for further treatment of the chips

Main functions

Picking up medium to large quantities of chips via a feed hopper
Drawing in and reducing the size of the chips through the chip reducer (optional) and feeding them into the pump-back tank
Dosing the chip/cooling lubricant mixture to the return flow pump by means of a circular scraper
Transporting the chip/cooling lubricant mixture through the return flow pump to the separator/filter system
