PRAB introduces its diagonal-shaft centrifuge

PRAB’s centrifuge/wringer efficiently adds value to scrap metal while reclaiming up to 98 per cent of valuable cutting fluids.

In addition, dry chips ensure compliance with EPA regulations when transporting for recycling.

“Processing chips and fluid prior to transport not only saves valuable floor space within the plant, but also offers higher market value for scrap metal, and dramatically reduces fluid disposal costs and transport risk,” says Mike Hill, VP of Sales and Marketing.

PRAB’s engineered diagonal shaft design works with gravity to feed flowable, wet chips from an input conveyor. The straight-line feed eliminates choke points and facilitates uninterrupted material flow.

The centrifugal motion within the rotating bowl creates 700 g of force, driving chips and fluid up the bowl liner. Fluids are then extracted through the bar screen and diverted for reclamation.

Dry chips are discharged for recycling, or conveniently briquetted and stored for future sales. Process rates of up to 10,000 lb/hr can be achieved.

“The use of a centrifuge for collecting fluid is a good way to cut annual coolant expenditures. Once the fluid is collected, PRAB Fluid Filtration Systems can perform the liquid-solid and liquid-liquid separation necessary for effective fluid reuse,” explains Tim Hanna, PRAB Managing Director.

Reclaiming fluids with a PRAB Guardian coolant recycling system to recycle used coolant can reduce new fluid purchases by up to 75 per cent and waste fluids up to 90 per cent. The Guardian system is a proven fluid reclamation management tool for operations with industrial coolant or washwater reservoirs. Free-floating and mechanically dispersed tramp oils are reduced to 0.1 per cent or less at process rates of 90 to 1,500 GPH. Guardian systems operate on a continuous overflow process providing multiple passes to prevent rancidity.
