The result being dust was escaping several processes, the working environment was consistently dusty. The plant is limited for space and has many truck movements.

Solution

A Mideco model 9A was installed thus increasing the volume of air being managed and still fitting in the limited space.

Note

One of the old dust collectors was overhauled and upgraded then re-installed as part of a new vacum system which the plant also needed.

Nickel Storage Shed

The ESP Alliance engaged Mideco to provide a dust and diesel fume management system for the port’s nickel storage shed. They required compliance with WA Mine Safety and Inspection Regulations 1995 & Australian Standard 1668.2-2002 inside the shed while still meeting environmental license conditions outside the shed.

The solution developed included M&H Diesel Particulate Filters for the loaders, use of the existing Mideco dust collectors for dust management, axial air movement fans and a Mideco reverse air filter that delivered diesel fume management with dust filtration. The Mideco reverse air filter used a heated bag cleaning system to protect the filter bags from the moisture contained in the moist air stream.

The ESP Alliance engaged Bilfinger Berger Services for site works including civil, electrical and installation.

To meet the deadline, Mideco delivered the equipment to site within 2 months and following the BBS installation works, achieved practical completion within 3 months.
