Luehr filter case study: GR Engineering/Integra Mining Ltd

The Problem

As part of its new Randall's Gold Project, located around 60 km southeast of Kalgoorlie (Australia), Integra Mining installed a large crushing and screening plant. This part of the process produces the largest amount of dust by far, which if left untreated can cause serious environmental problems.

Solution

To address this issue, an integrated dust extraction system was designed to capture the dust and return it to the process. This was achieved by the installation of a Luehr DF Fabric Filter. Its flat horizontal filter bag arrangement allows for a quick and safe inspection of the clean air chamber and bags, therefore eliminating the need to use tools or lifting gear to access the filter bags. Bag changing can be conducted from the generous adjacent access platform and does not require maintenance personnel to enter the filter.

As with most of the company’s designs, the filters used on this project are based on a modular concept. This allows the filters to be fully assembled with filter bags, pulse cleaning system and electrical controls. The complete unit can then be factory tested prior to shipment which not only ensures the filter is fully functional on arrival at site, but also reduces site installation errors, time and labour.

Result

The system was installed on time and commissioned without any issues. The plant has since been reliably producing hydrated and is meeting all expectations.
