To control the dust created during ship loading with bulk Gran-am fertilizer, 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 labor, port charges and shipping times.
The development of Central Station and the landmark Central Walk were awarded to international contractor Laing O’Rourke who proposed an innovative design with numerous benefits, including satisfying a key requirement that construction works needed to take place while keeping the existing station and train services operational.
After reaching the limits of drilling and blasting without creating excessive vibration and dust for the surrounding environment, Breendon need to find another viable solution. Rock excavation specialists AJ Gammond provided an innovative solution.
City Rail Link (CRL) is Auckland’s first underground rail line and the largest transport infrastructure project ever undertaken in New Zealand. CRL will transform the downtown Britomart Transport Centre into a two-way through-station, doubling the capacity, reducing travel times and supporting a growing population with a world-class transit system.
A critical aspect of any tunnel construction is ventilation design and dust control, so that workers exposure to fumes and dust are reduced to safe, acceptable levels. There are many types of ventilation design and dust control systems and as each tunnel is unique so is each ventilation design and dust control solution.
The Metro Tunnel provided some unique challenges for the ventilation design, including space and noise constraints plus the location on excavation works within the CBD. The design was created using Ventsim Design 5 to simulate ventilation, airflows, pressures, heat, gases, radon, fire and other key ventilation data to be considered, along with managing the financial constraints of the project.
The Greenbank Sewer Rising Main project was undertaken by Diona in November 2019, for the Logan Water Infrastructure Alliance and involved the installation of 5.6 kilometres of sewer rising main pipeline. They hired a JMS-20-MDT (Diesel, Track) dust collector from Grydale Rental to manage the silica dust created as a result of trenching through sandstone.
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. 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.
Our clients’ site expansion works, included a tender for a dust extraction system to manage dust created by two secondary and tertiary cone crushers and three screening plants. Grydale were awarded the contract to design, manufacture and install a Grydale JMS 48 F-Series Dust Extraction System. This unit provided 38,000m3/hr of air flow at -2.0kPA, which offered the capacity to extract dust from the two secondary and tertiary cone crushers and three screening plants.
