The type RIK pump back station is a compact chip conveyor station that may be integrated into a machine bed. It is used for the unmanned transport of medium amounts of chips and cooling lubricants from the processing machine to a filter. This construction unites the characteristics of conventional solutions from chip conveyors and separate pumping stations into a combined unit. Chips that result during the machining of materials such as castings or aluminium are particularly suitable. Steel chips are suitable only if they are of uniform length and are in small quantities.
The chips and the cooling lubricant arrive from the machine tool into the screw trough. One or more screw conveyors transport the chips horizontally directly into the chip reducer. After the chips are reduced, they as well as the cooling lubricant arrive in the pump back tank. The chip/cooling lubricant mixture is then fed uniformly into the return pump, which transports it by return pipe to the central or decentralised separating/filtering unit
The controlled interaction between pump and metering unit ensures safe chip transport, independent of the chip shape and the resulting amount of chips or cooling lubricant. For small chips without a tendency to form clusters, no chip reducer is necessary.
