Coolant recovery

Coolant = cutting oils and emulsions

Valuable raw materials are recovered with machinery and equipment for the separation of coolant from parts or swarf. The coolant can, after the separation, be returned to the processing machine. A higher price is usually achieved when selling the swarf due to the lower residual moisture. Grade purity and low residual moisture are the most important tasks of a modern and efficient system for coolant recovery in addition to the customized machinery and equipment. Residual moisture below 2% is required and achievable for most swarf types. An oil content of 15-25% in the case of unprocessed swarf and parts shows how quickly the costs for a coolant recovery plant can be amortised.

Applications:

• Swarf: Short, long, clustered
• Parts: Bulk material, individual parts
• Materials: Steel, stainless steel, aluminum, brass, cast iron, bronze, copper, tungsten, titanium, molybdenum, and much more

The centrepiece of any coolant recovery system is the centrifuge. This is designed in size and type according to requirements and integrated into the system tailored to customer needs. Manually operated centrifuges for small quantities, continuous or batch-operated centrifuges for medium and large quantities, as well as swarf crushers, conveyor systems and loading systems for containers are included in the extensive product portfolio.

Machinery and systems:

• Manual: Polar RPC, F, FK
• Automatic: Hydro-Polar E, Disk-Polar D, Permolex-Polar K, Robot-Polar RPC, RF, RFK, KRP
• Capacity: 12 l/batch to 10 m³/h, depending on material weight and machine type
