BloApCo is your quality supplier for pneumatic scrap removal

Thousands of installations worldwide prove the point. Since 1933, BloApCo engineers have applied their experience to the need for an upgraded, expanded or totally new system. Using their background in working with a wide variety of scrap materials and applications, BloApCo engineers adapt BloApCo manufactured components to provide an efficient integrated scrap removal system. BloApCo builds the industry’s toughest; Shredders, material Handling Fans, Scrap Conveyors, Trim Cutters, Diverters, Cyclones, Material Separators and other pneumatic system.

Separating Pneumatically Conveyed Material

Characteristics of a Cyclone Material Separator A cyclone is a simple, time-tested device that works with up to 98% efficiency. Sitting on your plant's roof, it takes up no valuable floor space, has no moving parts to maintain and its location provides ample surge capacity to give your baler time to work.

In-plant noise is not a concern when using a rooftop cyclone. And a cyclone is very forgiving as it can take a mix of just about any materials, regardless of density.

Dust travels with the scrap into the baler where it is contained without the need for dust collection barrels. Because the cyclone uses low air pressure, dust leaks are less likely to be a problem than in in-plant material separators where internal air pressures are higher, blowing dust back into the plant.

The height between the cyclone outlet and the baler hopper allows storage space, or surge, to allow the baler time to cycle and tie off bales. The surge space also provides additional weight over the baling chamber to increase uniform density. Low bale density is a recurring problem with indoor material separators. They don't allow the surge necessary to give a baler time to cycle and tie its bales -- causing plugs that can shut down production.

If an indoor material separator is desired, BloApCo can design one with an inclined air tight conveyor system to convey material higher and improve the surge. The conveyor also acts as an airlock to prevent the escape of dust back into the plant.

Characteristics of Under-the-Roof Material Separators An indoor material separator is out of sight for plants situated in industrial parks sensitive to "visual pollution" and requires no holes in the roof that could create weather leaks.

Indoor units also greatly reduce problems in maintaining and containing conditioned air. In hot or cold climates, precious energy dollars are saved through maintained plant temperatures and relative humidities.

What is a Cyclone?

Think of a centrifuge in a can, mounted on your roof with one job to do -- separate scrap and/or waste material from the stream of air that conveys it to the cyclone.

That whirling air and scrap mixture, pushed over 5,000 feet a minute by a material handling fan, is blown into the cyclone where centrifugal force drives the scrap to the cylinder outside wall. Because the cyclone is a larger diameter than the conveying pipe, the speed of the spinning material begins to drop and gravity takes over, allowing the material to spiral down a tapered area leading into a baler chute or other receptacle. At the same time, the conveying air escapes upwards through the center to the atmosphere or returned via an air filter inside the plant.

The high efficiency of a cyclone design allows material -- whether hand-sized or near-microscopic -- to be pulled out and captured.

What is a Horizontal Separator?
Remember that cyclone, or centrifuge in a can? A BloApCo horizontal material separator brings the cyclone inside your plant and lays it on its side (rotates it 90 degrees) so the air spins around a horizontal axis.

While competitors' material separators rely on flat screens to set at delicate angles to separate scrap and/or waste from the conveying air stream, BloApCo's horizontal material separators do not. Like the roof-top-cyclones, they force the material to the outside wall, then down a tapered section for collection while the conveying air exits through the center and out the end to the balancing fan and filter.

Note: Material separators use flat perforated screens that are susceptible to clogs if the customers change either the product mix, average product density entering the separator or the rate of entry of the scrap. In any case, the material can penetrate the air curtain and barrier that acts as a lubricant separating the screen from the material and air mixture. When that air curtain breaks down, the conveyed material will block the screen causing a system plug.
