Air Slide Belts –All You Need To Know

What are Air Slide Belts?

Air Slide Belts (also recognized as Air Slide Conveyor Belts, and Pneumatic Gravity Conveyor Belts) are a kind of conveyor belt that is used in dry solid powder conveying. This process of transportation is cited to as ‘Pneumatic Conveying’ by which pneumatic gravity conveyor systems protect long distances and transport materials from some point to another by means of air-activated gravity. 

As an outcome, the belt needs a level of air absorbent to allow the air activated gravity method to send air up and through the conveyor belt, letting the power to carriage through the conveying system from point A-to-B. 

What are Air Slide Belts Made from?

Air Slide belts (Air Slide Fans, Air Slide Blower) can be made from a number of resources in mixture. However, some belts are created from 100% polyester or nylon. The major raw resources that air slide conveyor belts such as Air Slide Fans and Air Slide Blower are created from are usually; nylon, polyester, P84 Polymides, or Nomex. 

The finest air slide belts are abrasion resistant, rot and mildew resistant, while also being able to be utilized in temperatures reaching from 30’C to 150’C.

A decent air slide belt creator will manufacture a belt with resources that reflect the requirements of the solution. Each resource can be laced to a required air absorbent, depending on the ‘holes’ from which the low-press air needs to purify through the belting resources. 

Mostly, these types of air slide conveyor belts are solid woven using the warp and weft threading technique. However, it needs demands of a different weave, creators can modify the weave to fit the solution.

The belt can differ in breadth from between 150mm to 16500mm, again subject to the solution requirement. Moreover, the density of the ply from which the belt is intertwined can range from 4mm to 8mm as per the demand.

The Process of Fluidization

The conveying solution itself uses an enclosed conveyor system, which confirms no raw material is left behind, nor does it drop off the air slide conveyor belt. All of the mandatory powder is carried from one part to another using a low-pressure air flow from beneath the air slide conveyor belt. 

During the conveying, the powder material is put into an absorbent state (pulverized) within the ‘fluidizing beld, before being carried through the pneumatic conveyor and outreach the compulsory journey.

The air-activated gravity of the slide conveyor belt, slope from which the system is produced to, allow the material to flow and move through the conveyor channel in a fluid way.

The belt itself sits inside the centre of the pneumatic gravity conveyor, in the channel between the powder fan and the air chamber. This is where the fluidized powder moves in a fluid way through the conveyor belt part of the system.

The type of fluidify beds and pneumatic carriage may differ on the material being accepted through the pneumatic conveyor.

Different Fluidizing Beds

Bed fluidizing can be both solid and fluid form (gas or liquid).  Fluids flowing through a coating of bulk solid at a ‘fluidization speed’ can loosen the individual particulates to confirm they enter a ‘suspended’ method. This is how a fluidized bed is shaped and is appropriately named ‘fluidization’. The flow of powder certainly acts like that of fluid to produce this method and bed is ready for carriage.

If the speed changes to become more extreme, atoms are release into the pneumatic carriage method.

Classically, there are three methods of fluidized beds that may happen during the fluidizing method. These are:

Homogeneous Fluidized Bed

A homogeneous bed is the name given to describe a fluidized bed that reflects the velocity increase of the fluid creating a balanced dilation of even distribution across the base layer.

Inhomogeneous Fluidized Bed

The inhomogeneous bed is the term given to define a fluidization method that results in weightier atoms within the lesser part of the fluidized bed. If gases are used as the ‘liquid’, foaming takes place, which ruptures at surface level, giving off a look of boiling liquid within the fluidized bed.

Channeling Fluidized Bed

When finer grain bulk powder is the solid method being carried, the creation of a fluidized bed may not happen. This is due to the atomsstick to each other and natural flow networks being shaped.  Consequently, in demand to produce a fluidized bed, manual rousing is required.
