Incitec Pivot is one of Australia’s largest suppliers of fertilisers, dispatching around two million tonnes each year. One of their production processing facilities is located at the Port of Brisbane where they manufacture Gran-am, a granulated ammonium sulphate fertiliser, used on its own or as a source of nitrogen in blended fertilisers. The product is shipped worldwide.
To control the dust created during ship loading with bulk Gran-am fertiliser, conveyor speeds had to be reduced to 100T per hour. This reduction in ship loading time causes a significant increase in operating costs through increased labour, port charges and shipping times.
Incitec already uses Grydale fixed dust collection systems within their manufacturing and processing facilities which prompted them to contact our team to discuss a potential solution.
From experience of other ship loading and unloading projects, our in-house engineering team calculated that the Grydale JMS-50-MES dust collector could be positioned at the port to effectively manage the dust from loading conveyors, and allow for increased conveyor speeds.
The JMS-50-MES is a mobile dust collection unit that can be easily positioned on site using cranes and castor wheels. The mobile dust collector can be easily moved when not required for ship loading.
The use of the dust collector for ship loading has yielded impressive results and the unit will remain at the Port of Brisbane to provide ongoing dust control.
Increased ship loading speed
The first 10,000T ship arrived in Port and was loaded within 2 days – three days earlier than scheduled.
Increased conveyor speed
The conveyor speed was increased from 100T per hour to 540T per hour.
Significant cost savings
The increased speed of ship loading represents a huge operational cost and time saving for ship loading, with dramatically reduced port demurrage charges and reduced labour costs.
In addition, the dust discharged from the dust collector is captured in 1T bulker bags and can be utilised as product.
Sales and Rental Options
Grydale offers flexible rental and purchase options for 6m³/s – 60m³/s (12,000CFM to 125,000CFM) mobile dust collectors. These units can be used to manage ship loading and unloading of a wide range of products either via clamshells or conveyors.
