:: Dr Chris Meimaris Receives Award of Doctor of Engineering from The University of Queensland

 

Dr Chris Meimaris received the award of Doctor of Engineering by The University of Queensland in December 2012. The Doctor of Engineering degree is a higher doctorate made by the University for substantial original and distinguished contributions to engineering in Australia and internationally. Dr Meimaris' dissertation entitled "Original work on grinding mills, ring motors, foundation systems and gear drives" presented a selection of his national and international publications that have established him as a world expert in these fields.

Dr Meimaris' major achievements include the remedial design of the world's largest gearless drives in including those at Cadia, Antamina and Collahuasi; the development of mathematical models that accurately simulate the nonlinear dynamics of ring motor stators for gearless mill drives; development of mill systems analysis to predict the vibration and deflection behaviour of geared and gearless mills including foundation dynamics and soil-structure interaction; and in mill design auditing and manufacturing quality control. In 2001, Dr Meimaris started is own company, "Engineering Analysis and Design" (EAnD). The company has been extremely successful. EAnD has developed a world-wide reputation for mill system analysis work and mill design audits since 2001.

"EAnD has developed into a specialist company that provides a "vertically integrated" approach to mine owners who wish to purchase large comminution equipment" said Dr Meimaris. "By vertically integrated, I mean that we provide a full technical service from specifying the mechanical equipment, then analysing the design for conformance to the specification, developing and/or analysing the complete mill or crusher system model and finally providing quality inspection and non-conformance resolution during manufacture".

Dr Meimaris believes that more rigour is required in grinding equipment mechanical design. He said "There is a size limit in mills beyond which the simplified design methods used by some mill vendors are no longer valid. The recent failures of grinding mills in South America indicates that this limit may have been reached."
