VACUUM CONVEYING
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.
PRESSURE CONVEYING
Positive conveying uses a blower to blow product metered into the conveying line from a material source to a destination or multiple destinations up to 300m away and at rates up to 30tph.
In the Lean Phase pressure conveying mode, product is separated from the conveying air by either a cyclone receiver, stand alone filter or a filter fitted to the receiving vessel before the clean air is released to the atmosphere. As the air has been compressed prior to mixing with the product, heat generated from the compression can result in an increase in product temperature. Pressure conveying is ideally suited to the conveying of materials to various destinations such as weigh hoppers in a ring main system with the excess product and conveying air returning to the material source.
