My PhD research aims at testing representative feed materials from selected mining operations through the GRolls^® to investigate size reduction and energy consumption performance, potential benefits to subsequent mineral liberation and the potential for integration into existing or new comminution circuits. The test program will also compare performance and processing benefits of dry and wet test conditions and compare GRolls^® results to other comminution technologies available at the university and assess energy, capital and operating costs of new or modified comminution flow sheets. 

The outcome of the research could identify potential simplification of mineral processing flow sheets using the GRolls^® technology for many mining operations, reducing their power and grinding media consumption, and dramatically reducing water consumption, and all ESG benefits derived during mineral processing. The research will test the laboratory GRolls^® unit under a wide range of feed materials and crushing configurations which could replicate indicative mineral processing flowsheet scenarios and generate fine grained particles for detailed/comprehensive mineral liberation testing and analysis.
