The first step in considering vacuum conveying is defining the upstream process from which material will be sourced. This can include loss-in-weight feeders, volumetric feeders, mixers, reactors and extruder hoppers. The type of operation, whether batch or continuous, will impact how your system handles the incoming powders. The next factor to consider is the bulk density of your powder. This will determine the size of your receivers, as well as your conveying velocity. For example, lighter-weight powders need larger receivers than heavier-weight materials.

Choosing a Vacuum Conveying System

Once you have your material flow figured out, the next step is to select the type of vacuum conveying system that will best suit your needs. You can choose from two basic systems: dilute phase and dense phase. Dilute phase carries the powder suspended in a fast-moving air stream and suits a wide range of free-flowing materials. Dense phase moves material more slowly in slugs, which reduces segregation and damage to fragile or blended products.

Saving Floor Space

Your final consideration should be your facility’s floor space, as vacuum conveyors have a much smaller footprint than mechanical conveyance equipment. They can also be mounted on mobile or column lift conveyors to easily load or unload process vessels from above, reducing the need for workers to be exposed to hazardous conditions.

For the most demanding powder transfer applications, turnkey pre-engineered systems are a great option.
