MRM produces zinc, lead and silver from the open cut mine which is then processed and stored onsite before being transported to Bing Bong Loading Facility and shipped to customers all over the world.
At Glencore’s loading facility at Bing Bong, Zinc is stored in a bulk storage shed which needs to be fully contained to protect against spillage and ensure environmental security and prevent loss of valuable product.
Grydale were commissioned to design, manufacture and install a dust collection system to manage dust within the Zinc Bulk Storage Shed.
A Grydale JMS 60 dust collector was used to place the zinc storage shed under negative pressure. A plennum was used on either side of the access door that was used to feed air into a common duct run back to the dust collection system.
If there is insufficient air flow entering the storage shed, the air flow meter on the dust collector turns up the Variable Speed Drive (VSD) to generate more air volume. Equally the air flow meter will turn down the VSD so the dust collector uses less kW for the same amount of volume depending on the temperature and conditions. This results in significant power savings.
The JMS 60 Dust Collector has a filtration efficiency of 99.99% at 0.067microns and air is exhausted via the clean air stack. Zinc dust is discharged through the hoppers to product recovery drums and then returned back to the storage facility. This not only minimises health, safety and environmental risks but also ensures that operational efficiency is maintained by recovering product.
