The Pneumati-Con filling system for free-flowing bulk solids conveys and weighs material before discharging it into bulk bags.
The filter receiver of the Pneumati-Con vacuum dilute-phase pneumatic conveying system is mounted on load cells - enabling the system controller to weigh incoming material at high rates, then at steady trickle-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-Centrepost bulk bag, opening a slide gate valve at the outlet of the filter receiver and allowing the weighed batch to gravity discharge at high rates. 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.
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.
Connecting an empty bag consists of attaching the bag straps, pulling the spout over the inflatable collar and pushing a spout inflator button.
