Fresco Systems Australasia  have released an integral dust collector mounted directly on the top of a ribbon blender. The dust collector can return collected dust into the product stream. It reduces product wastage and removes the need for the operator to empty waste dust collection drums.

When filling blenders, operator must cut and tip 20 and 25kg bags of various powders. This creates dust and should be controlled by some method of dust collection. Design airflows should be 1-1.5m/s through the blender opening in order to prevent the operator being exposed to the dust. Depending on the particle size and bulk density of the powders, carryover to the dust collector varies.

A stand alone or central dust collector discharges collected product into a waste drum, which must be emptied by the operator. This requires manual handling to lift and tip the drum exposing the operator to the dust as the drum is emptied.

The Fresco Systems Australasia’ integral dust collector is rated to 4,600m³/hr and is fabricated in stainless or carbon steel depending on the application. Air flow is created through a corrosion- resistant moulded PVC fan, which has a noise rating of 74dba. Dust is collected on the two cartridge fillers (41m²), which have an efficiency of 99.99% to 0.5micron.

Clean filtered air can then be returned to the process environment reducing the loadings on HVAC systems. Reverse pulse cleaning discharges the collected dust from the filters back into the blender ensuring no product is wasted. Access to the filters for inspection and replacement is through the side access door. The integral dust collector is flanged directly to the top of the ribbon blender.

It is self-contained and easy to retrofit to new or existing systems. Designed to suit all Fresco Systems Australasia’ standard ribbon blender sizes from 150 litres up to 4,000 litres, the dust collector can be adapted to a hopper transition reducing the discharge to fit smaller sizes blenders.
