Australian Plastics Reprocessing recently contracted Polex Environmental Engineering  to design, manufacture, install and commission a dust extraction system to extract and filter fine dust generated during the recycling of compact discs in a shredder.

Polex selected a Modular Reverse-Pulse bag type dust collector for this application since the shredding machine was in operation continuously and the dust being generated was fine. A reverse pulse unit is ideal for continuous operation since the filters are cleaned while the fan is in operation.

Polex designed, supplied and installed a Modular Reverse Pulse Bag type dust extraction system with 2000 m³/h airflow capacity, 10 m² filter area and a 4 kW centrifugal fan. The waste is discharged into a 185 L bin positioned under the dust collector.

The dust extraction system was designed for a 2000 m³/h airflow capacity. A 4 kW centrifugal fan was used to supply the airflow through the dust extraction system. The waste is discharged into a 185 L collection bin positioned under the hopper.

Folded and bolted 1.5 mm thick Galvanised sheetmetal panels are used for the construction of the Modular Reverse-Pulse dust collectors. Optimal material thickness is selected to minimise cost whilst maintaining strength while the dust collector is in suction and while the unit runs through the cleaning cycle. Polex dust collectors have been designed with smooth internal surfaces to minimise dust hang-up in the filter chamber and hopper.

The dust collector legs are fabricated from heavy Square Hollow Section (SHS) steel as standard, making them suitable for heavy duty industrial sites.

All Polex dust extraction systems are structurally certified to withstand high wind loadings.
