This investigation is one in the series of studies involving the performance of grinding process, morphological characteristics of grinding grits and topographical features of grinding surfaces. This paper introduces results of interrelation between grit morphology and grinding performance in pressurized groundwood process. These lab scale studies were done with single layer grinding surfaces using different aluminum oxide grits as grinding media. Results are compared to the performance of conventional vitrified ceramic pulp stone made with fused aluminum oxide grits. Results showed clearly that the energy performance of groundwood process could be improved by improving grit morphology on single layer grinding surfaces. The information of these studies has already been used in development of a new kind of grinding technology based on single layer grinding surface for mechanical pulp manufacturing. This new technology is called Galileo grinding technology.
