Vacuum conveying is often a low cost method of pneumatic conveying where product can be conveyed up to 60m at rates up to 15tph.

It is ideally suited to the loading of extruder hoppers or direct loading of blenders or other such vessels.

The receiving vessel is put under vacuum and the product metered into the conveying line at a rate suitable to the conveying velocity and at the desired air to product ratio. 

Filters fitted to the receiving vessel or a stand alone filter separate the product from the conveying air prior to the air passing through the vacuum source.
