PRAB - Tramp Metal Separators
PRAB offers a complete line of tramp metal separators to remove bar-ends, broken tooling and other solids from chip flow protecting processing equipment from damage.
PRAB`s five unique separators are engineered to perform at different levels to efficiently handle the variety of metal chips and turnings produced by today`s high-speed, metalworking industry.
- Increase productivity by reducing downtime
- Save time and money on costly repairs
Model O
A heavy-duty oscillating conveyor fed air classifier designed for large chip processing systems. The unit positively separates all types of solids from material flow. Typical throughput of metal chips are 200 ft3/hr (5.6 m3/hr). A 20 hp blower and plenum system are designed to recirculate airflow, reducing misting issues
Model V
A vibratory feeder/air classifier separates solids from wet chips and turnings at a rate of 100 ft3 (2.8 m3) of metal scrap per hour. Return air system recirculates airflow, reducing misting issues.
Model G
A gravity-fed, free standing air classifier can process metal scrap at rates up to 80 ft3/hr (2.2 m3/hr). The unit positively separates tramp metal from material flow. A 20 hp blower and plenum system is designed to recirculate air flow, reducing misting issues
Model R
The R Separator is specifically designed to feed PRAB Diagonal-Shaft Wringers. The unit incorporates a blower and rotary air lock mounting to the wringer infeed conveyor. Two adjustable plenums control air flow into the wringer infeed. The model R is capable of being "fine tuned" when needing to divert very small solids from the chip flow. The unit can process metal scrap continuously at rates up to 60 ft3/hr (1.6 m3/hr)
Model S Separator / Screener
Generally used for cast-iron applications, the S Model is a vibrating bar screener deck. It can be provided as a stand alone unit or it can also attach to the inlet of a wringer or briquetter to separate flowable chips from solids and reject castings
Separators serve as key components in any chip processing system. They remove bar-ends, broken tooling and other solids from the flow to protect down stream processing equipment from damage. PRAB’s five unique separators are engineered to perform at different levels to efficiently handle a variety of metal chips and turnings. Covered by PRAB’s one-year warranty.
The Model G Separator, illustrated feeding a PRAB Vertical Axis Crusher (VAC), is a moderate volume separator. It includes a self-contained ducted air recirculation system to minimize oil misting. Chips and turnings are typically dropped into the hopper inlet by an external feed conveyor.
Designed for higher volumes and nested wads of scrap material, the Model O Separator has an oscillating conveyor as a metering component. It is used to effectively spread the material across the width of the oscillating deck, prior to entering the air classifier section. It is illustrated feeding a PRAB Vertical Axis Crusher (VAC), which reduces metal scrap into shovel grade chips. The separator also features the same ducted air recirculation as the Model O system, to minimize oil mists.
The Model R Separator is designed for use with flowable wet chips and is used in conjunction with a PRAB diagonal shaft centrifuge. Chips are usually fed into the inlet by an elevating feed conveyor. A rotary style air lock meters the chips into the continuous air blast where separation of the metal chips from heavier solids (bar-ends) takes place.
Note: These drawings indicate the general operation, size and configuration of the air classifier PRAB parts separators. The actual configuration, operating capacity and dimensions will reflect the type of materials being processed and other equipment required downstream in the system.
