Hazardous handling no problem
29 Mar 2000
As part of a materials handling contract for Sorex, a producer of hazardous materials for controlling vermin and airborne pests, the weighing and metering specialist Rospen had three major problems to overcome - access, accuracy and dust containment. Precision metering in a contained environment was needed to elevate and transfer a masterbatch containing the active ingredient from tote bins to a mixer. The access problem was overcome with a weighed Rospen metering screw feeder, mounted above the mixer, which is automatically refilled by a flexible screw conveyor from the tote bin. Accuracy was ensured by weighing the metering screw feeder to perform a loss-in-weight batch rather than relying upon the mixer weighing system which had previously given poor addition accuracies.
