description Disclosed herein are apparatus and method for measuring, during operation, the degree of sharpness of grindstones in a wood pulp grinding machine of the type where one motor drives two grindstones, each having two or more pockets for loading timber. In accordance with the apparatus and method, the power of the motor and the feed rates of the pockets are simultaneously measured. After a predetermined time interval, during which the operating conditions of the machine change, these measurements are made again. The degree of sharpness of the grindstones can then be calculated using the measured values of power and feed rates.
