- In this paper, attempts have been made for the first time, to experimentally evaluate the transformation, decrease and dissipation of the energy consumed during grinding by measuring the physical, chemical and mechanical properties of the ground material. By using a standard shear tester (Jenike shear cell) the unconfined yield strength and major consolidation stress of the ground material were measured immediately and after a period of storage. Also the solubility rate (ground material in water) of the same materials was defined simultaneously by measuring the electrical conductivity. The new experimental results aid the understanding of the behavior of ground material and may help provide better engineering tools for industrial design. A clear correlation has been found between solubility and flowability. Therefore, the flowability variations can be explained in the same way as the solubility.
