Pneumatic In-line Weigh System Simplifies Bag Filling
Flexicon Europe has introduced a pneumatic gain-in-weight filling system that automates delivery of free-flowing bulk solids from down-stream silos or processing lines to individual bulk bags. The integrated conveying and weigh batching system helps organisations increase throughput and due to the closed discharge arrangement it also prevents material loss and site contamination.

The filter receiver of Flexicon's Pneumati-Con® vacuum dilute-phase pneumatic conveying system is mounted on load cells, enabling the system controller to weigh incoming material at high rates and then at steady dribble-feed rates, stopping the flow once an accurate batch weight has been reached.

Pressing a "fill" button on the control panel actuates a bag inflation blower on the Twin-Centerpost™ bulk bag filler to remove creases in the bag, simultaneously opening a slide gate valve at the outlet of the filter receiver allowing the weighed batch to gravity discharge into the bag at high rates, a vibratory deck densifies the material to stabilise the bag. During the transfer process a port within the discharge spout vents displaced air and dust to a remote bag house.

A secondary set of load cells mounted beneath the bulk bag filler allows the system to confirm the final weight of the filled bulk bag. 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.

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. Connecting an empty bag consists of attaching the bag straps, pulling the spout over the inflatable collar, and pushing a spout inflator button.

The pneumatic gain-in-weight filling systems complement Flexicon's other 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 dumpers, bag dump stations, and integrated plant-wide bulk handling systems with automated controls, all of which are available to industrial, food and pharmaceutical standards.
