PRAB offers the vertical axis crusher and diagonal-shaft centrifuge system for reclaiming cutting fluids and reducing bushy metal turnings into dry shovel-grade chips.

The vertical axis crusher provides efficient processing and recycling of scrap metal, handling as much as 2,500 lbs/hr. The engineered crusher is equipped with an exclusive solids ejector that automatically discharges bar ends that can damage the equipment and stop metal processing. This feature provides maximum uptime and eliminates the need for unscheduled labor and downtime to dislodge clogged material. PRAB’s steel belt conveyor elevates and transfers chips from the crusher into a tramp metal separator to remove bar ends and other tramp metals, protecting the wringer and other downstream equipment.

PRAB’s engineered diagonal shaft design works with gravity to feed flowable, wet chips from a steel belt 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 as much as 10,000 lbs/hr. can be achieved.

Dry chips are discharged overhead pneumatically. Chips can be blown into a trailer bed or container with an automatic swivel chute for even filling. Settled fines are re-circulated back into the system using a settling tank with a re-circulating drag conveyor. PRAB’s Guardian coolant recycling systems can be added to the system to reduce free-floating and mechanically dispersed tramp oils to 0.1 percent or less at process rates of 90 to 1,500 gph.
