Vacuum Conveying

Vacuum conveying system works on a cyclic operation where the system conveys for a set time or to a level, conveying stops, the discharge valves opens and the filters are cleaned. This sequence is then repeated. Continuous transfer can be achieved by utilising a rotary valve at the outlet of the receiver.

The product is introduced at the pick up point into the conveying line by various equipment such as suction lance, feeding hoppers, feeding screws, rotary valves, extruders etc.

The necessary gas flow is generated by the vacuum generator located at the far end of the line, after the vacuum receiver and thus the material is sucked through the pipeline and into the vacuum receiver.

In the vacuum receiver the gas is then separated from the product by flowing through a filter which rejects the solids. During every discharge cycle the filter is automatically cleaned via a compressed air blast.
