Client Overview

Our client is a private company who bring significant experience from the mining and stevedoring industries. Headquartered in Townsville, Queensland with operations spanning all of regional Queensland’s major Port facilities including Gladstone, Mackay, Townsville, Cairns and Weipa, our client provides stevedoring and integrated supply chain management for ocean cargos.

Our client is committed to investing in state of the art facilities and are focused on setting the benchmark for the delivery of solutions and innovating in areas of stevedoring, transport and logistic, efficiencies, servicing companies all over the globe.

Challenge

Our client has two 8000m2 sheds that store zinc and copper concentrate before being distributed to customers across the globe. Zinc and Copper dust needed to be fully contained within each shed to protect against spillage, avoid cross contamination and ensure environmental security. With the added challenge of having the port directly opposite Townsville, EHP limits placed on the client meant no visible dust was allowed to escape each building.

Our Solution – Grydale JMS 48 F-Series Dust Collection System

Grydale were commissioned to design, manufacture and install a JMS 48 F-Series Dust Collection System for each storage shed (zinc and copper) to manage dust created through loading and unloading product.

Ducting was installed throughout each shed to provide sufficient dust collection points to extract dust through a common duct back to the JMS 48 F-Series Dust Collector. This effectively placed each storage shed under negative pressure to contain all dust within the shed.

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 has resulted in significant power savings.

Each JMS 48 F-Series Dust Collector has a filtration efficiency of 99.99% at 0.067microns and clean air is exhuasted via the clean air stack. Real time particle detectors examine emissions coming out of the clean air exhaust and were tuned to alarm if EHP regulations were breached. All emissions are logged in the PLC within the main Motor Control Centre (MCC).

Dust is discharged through the two single hoppers via stainless-steel rotary valves to 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 that would otherwise be lost.
