09/10/2014: Dust control with gypsum powder prior to pelletizing

At South Pacific Seeds (Australia), processing seeds was generating dust when combining gypsum powder with a glue binder prior to pelletizing. Bags of gypsum were manually cut open and emptied into a bin and auger conveying to a rotary treater/pelletizer.


SPS solved the dust problem by switching to bulk bags and installing a forklift-loaded bulk bag discharger and two flexible screw conveyors feeding the rotary treater.

An iris valve at the bag spout interface above the hopper contains dust, as well as a Bag-Vac dust collector attached to the discharger frame. The 80mm diameter horizontal and inclined flexible screw conveyors likewise are completely enclosed. The small footprint of the conveyors overcome a constrained floor space in which the rotary treater is positioned in a tight corner.
