Crushing & Screening
Bulk ore crushing systems require a lot of power and must survive in dusty and high vibration environments. Logitech Engineering helped build and commission the Windimurra Vanadium Mine Crushing and Beneficiation circuit, utilizing a three stage course, medium and fine grade crushing and screening circuit. Three Gas Turbines were used to power the large crushing motors, which were used as the primary load for the 11kV distribution system. More...
Underground Mining
Underground mining equipment such as this Premron CHS longwall coal miner conveyor feeder is often subjected to extreme conditions including dust, humidity, vibration and washdown water. Continuous Mining Machines must be reliable in these tough conditions as well as compliant to AS60079 hazardous areas and AS3800 mining regulations.
In 2019, Logitech Engineering assisted Premron to assemble and commission this continuous haulage system for an underground coal mine in Central Queensland. The Earth Fault verification study was completed by AmpControl and ResTech, which included multiple transformers and variable speed drives mounted inside explosion proof enclosures. More...
Limestone Quarry
In 2019, Logitech Engineering assisted Corfields Electrical to redesign and upgrade the electrical and control systems at the Calliope Limestone Quarry owned by Graymont Quarries. The upgrade includes the 11kV and 415V power distribution systems including installation of Soft Starters for the Primary and Secondary crushers. When all three stages of the upgrade are completed in 2020, the limestone production rates are expected to increase significantly due to the improved reliability of the electrical power system.

Salt Mining
Salt mining is a low energy, low cost process, but the machinery is exposed to extremely high corrosion. Designing crushing and packaging equipment in a salt mine requires special attention to material selection and Ingress Protection. Good maintenance is the key to maintaining operational reliability.
