How does an air slide conveyor work?

The conveyor consists of a rectangular chamber separated by air-permeable, porous media. The media is placed along a horizontal plane to separate two chambers within the conveyor: An upper chamber to handle the material being conveyed, and a lower chamber to handle compressed air.

An Air Slide conveyor uses the forces of gravity to do most of the work without any moving parts. Material is fluidized through a porous media with low-pressure air. Material flow is achieved by sloping the air slide conveyor to match the fluidized angle of repose of the powdered material.

What is an air slide conveyor?

An air slide conveyor is a device for moving a variety of lightweight, fluidizable dry bulk powders, can move fine, dry material using pressure differentials and a flow of gas, typically compressed air or nitrogen. The material is totally enclosed within tubes or pipes, where differences in pressures on either side cause a flow of product. The air slide conveyor is a fluidized conveying system that just makes sense With minimal fluidizing air and a gentle incline, air slide Conveyors transport dry and fine-grained mineral bulk materials economically and efficiently.

Airslides have no moving parts. They are, therefore, often a far better solution than screw conveyors, drag chains and belt conveyors.

Air-gravity conveyors are typically manufactured in 10 ft | 3 m sections. Shorter sections are used to make up the exact required length of the total conveyor.

What is an air slide fabric in a cement plant?

The air-permeable (air slide fabric) layer separates the upper and lower troughs, the upper trough body as the material chamber, and the lower trough body as the air chamber. Air chute to air as the power, so that a certain pressure flow of gas, from the ventilation layer (fluidized bed) through the pores, so that the fluidized material to change the angle, the powder was “suspended” state. Air transport chute has a certain slope, when the powder is fluidized in the air suspension layer suspension, the rest angle decreases, when the tilt angle is less than the chute, by its own gravity and component of the role of powder flow forward, To achieve the purpose of transport.

How does a Air Slide Conveyor System work?

Air slide conveyors use a combination of air/gas flow and pressure differential in order to force powder bulk and dry bulk materials through the pneumatic system. This pressure is a negative pressure that forces the material and the positive pressure inside the equipment to move inside the pipe.

What a Air Slide Conveyor System is. Air slide conveyor provide some of the most efficient and practical methods of conveying bulk powder material. With some low pressure air, an aeration bed and a small incline (gravity), it can convey hundreds of tonnes of products over long distances.
The principle of pneumatic conveying is based on the fact that bulk goods can be moved by means of air through pipelines. The flowing conveying air transmits a propulsion force on the bulk material and thus conveys it through the conveying line.

What angle should an air slide conveyor be?

A 10 degree angle is recommended for most applications. Air slide conveyors also utilize traditional conveyor components such as diverter gates, flow controls, shut-off gates, and discharge chutes. Air slide technology can also be applied to your existing or newly manufactured storage bins.

When installed, an air-gravity conveyor is sloped slightly downward – normally at 6 – 8° from the horizontal. A benefit to air-gravity conveying is that the length of an air-gravity conveyor is limited only by available headroom versus headroom needed to accommodate the unit’s slope. Hypothetically, an air-gravity conveyor can be infinitely long – if the required headroom is available. In fact, air-gravity conveyors with lengths of 200 – 300 ft | 61 – 91 m are not uncommon.
