How do

vacuums work?

Compared to the Gough bucket elevators using gravity as a sustainable energy source, pneumatic conveyors either work with positive pressure or vacuum. With positive pressure conveying the material is pushed by the higher pressure on the feed side of the conveying system. Vacuum conveyors on the other hand pull the material with a vacuum that is created on the receiving side of the pneumatic conveying system.

Piabs 4 basic elements:

A vacuum source
A material feed device
A conveying line
An air-material separator.

Pneumatic conveyors work best with fine, fluidizable, dry powders and can easily flow through the conveying line. Other material types suitable for Piab include: flour, cement powder, carbon black, sugar, plastic pellets, food particles, tablets, sands, metal powders, and many more...

It generates a vacuum, and the conveyed material is transferred from the feeding point into the conveying line and then to the container.

During the conveying process, the filters protect the pump and the surrounding area from dust and small particles, and the air shock tank is filled with compressed air.

After each cycle, the bottom valve opens, and the material is discharged into a hopper or any other piece of equipment.

At the same time, the filters are cleaned with a filter shock or similar cleaning method in each cycle.

The safest option to convey powders

There are no moving parts that can shear objects or need to be lubricated, pinch points that would grab a piece of clothing or nip points where the gears would meet.

Eliminates the risk for contamination

Conveyed materials are transferred in a closed system, not being exposed to air.

Saves space

Pneumatic conveyors can even be mounted right below the ceiling, taking up only a fragment of space compared to a mechanical conveyor.

Eliminates spills in the production line

The closed pipelines greatly reduce the possibility of material loss.

Easy to clean and sanitize

Pneumatic conveyors usually have an in-built filter cleaning system that prevents the filters from clogging. 

Flexible and easier to maintain

Switching between materials and maintenance generally takes much less time compared to mechanical conveyors.

How to choose the right conveyor type?

There are several factors to consider:

Material characteristics - particle size, distribution and shape, hardness, the tendency to get hygroscopic and fluidize, moisture content, concentration, and bulk density.
Environmental factors - temperature, humidity.
Connected equipment characteristics - system transfer distances, throughput, height and angles.

The correct Piab and pump size can then be chosen based on these factors and quantified data to find the optimal conveying solution for you.
