Development of the Reflux Classifier
The device consists of a system of inclined channels attached to a conventional fluidised bed. The inclined channels permit significantly higher feed rates, with improved separation performance achieved as a result of the higher shear rates in the channels. Professor Galvin is the inventor of the Reflux Classifier. In 2003 the Reflux Classifier attracted the Queensland Enterprise Workshop Innovation Award for best invention. The Reflux Classifier was also a finalist in the Queensland Smart Awards (2006). Professor Galvin received the 2004 ACARP national Award for Research Excellence for Coal Preparation, and (with Ludowici MPE) the 2005 Business and Higher Education award for the best Research and Development Collaboration.
Since 2005, 22 units have been sold into Australia, China, New Zealand, United States, India and Mozambinque, with installed capacity of 15.4 million tonnes per annum.

The Jameson Cell
The Jameson Cell is a radically-different flotation machine that gives better performance than traditional designs. Jameson has been engaged in a long-term program to improve the performance of flotation equipment for mineral and coal separations and wastewater treatment. In the years 2000 to 2005, 52 Jameson Cells have been sold, to mineral and coal operations in Australia, Peru, Mexico, Israel, Zambia, China, Laos, and Bulgaria. In terms of economic impact, the largest contribution has been to the Australian coal industry, where in the same period of time, 39 cells have been sold to 20 sites. The installed capacity of these cells is 13.5 million tonnes per annum, and the value of the export coal recovered by their use is $1.35 billion dollars per annum. The importance of the Jameson Cell has been recognised by numerous awards.
