O.K. - but she acquired the skill over many years of experience. Suction Systems for the handling of non free flowing powders has advanced to become a very powerful tool by the same means; application of experience.

Advances in filtration efficiency have been a major step in bringing reliability to vacuum systems, often considered the poor relation in the world of pneumatic conveying. Fluidisation techniques have also been improved so that many powders can now be conditioned and made easier to convey.

The packaged vacuum system utilising a tubular receiver gives trouble free discharge of most 'hard to handle' powders and the negative pressure operation means that the equipment is virtually dust free.

Vacuum conveying has several advantages over the positive pressure alternatives, the main one being the lack of moving parts and the simplicity of the material pick up. Vacuum systems can also be used to simultaneously weigh as they convey, thus giving accurate data for throughput and stock control.

The equipment is capable of handling a variety of powders at rates up to 5000Kg/hr over distances up to 100 metres.

PCS, based in Stockport, UK, provides packaged vacuum systems with design features to cope with the most difficult powders. Tubular hoppers ensure 100% discharge without bridging and ratholing.

All clients' products are tested at production throughputs and clients are welcome to witness their tests before purchasing equipment.
