Flexicon Corporation (Australia) presents pneumatic gain-in-weight filling systems that convey and weigh free-flowing bulk solids before discharging them into bulk bags.  

Pneumati-Con vacuum dilute-phase pneumatic conveying systems feature a filter receiver mounted on load cells that enables the system controller to weigh incoming material at high rates, and then at steady trickle-feed rates, stopping the flow once an accurate batch weight has been reached.  

A bag inflation blower is actuated on the Twin-Centrepost bulk bag filler by pressing a ‘fill’ button on the control panel to remove creases in the bag, which also opens a slide gate valve at the outlet of the filter receiver, allowing the weighed batch to gravity discharge into the bag at high rates, as a vibratory deck densifies the material to stabilise the bag.   

A secondary set of load cells mounted beneath the bulk bag filler allows the pneumatic weigh filling systems to confirm the final weight of the filled bulk bag. A port within the discharge spout vents displaced air and dust to a remote bag house.  

The controller then releases the bag straps and deflates the spout seal, allowing the operator to tie-off the spout and remove the filled bag from the weigh filling system.  

An empty bag can be connected by simply attaching the bag straps, pulling the spout over the inflatable collar, and pushing a spout inflator button. While filled bags are being removed and empty bags attached, a subsequent batch is being conveyed to the filter receiver and weighed, ready for another fill cycle in the pneumatic weigh filling systems.    

In addition to the Pneumati-Con pneumatic weigh filling systems, the company also manufactures various types of pneumatic conveying systems, batching systems and bulk bag fillers as well as flexible screw conveyors, bulk bag dischargers, bulk bag conditioners, drum/box/container tippers, bag dump stations, and integrated plant-wide bulk handling systems with automated controls, all designed to meet industrial, food and pharmaceutical standards.
