Abstract

The aim of the study was to determine the effects of grindstone surface profile in laboratory grinding with a view to reducing energy consumption during grinding. Tests were performed with several different stones. The results obtained with the stone having 30 % large grits and 70 % small grits suggest energy can be saved without adverse effects on the groundwood pulp. The results need to be verified on a larger scale. Stone conditioning experiments showed that basically the stone changes from sharp to dull as the grit shape changes. No major changes were observed in the depth of the sharpening pattern. There exist an optimum stone sharpness: grinding with too sharp or too dull a stone adversely affects groundwood quality. It was also found that the angle of the sharpening pattern affects the infeed pressure needed to achieve a given production rate
