ABSTRACT:
A method for controlling the water jet sharpening sequence of a pulp grinder is provided, wherein a high-pressure sharpening water jet is directed toward a surface of a pulpstone with a water sharpening apparatus. An actual quality value of the fiber pulp is determined for at least one variable, and a target quality value is defined for each of the at least one variable. The actual quality values and corresponding target quality values are transmitted to a control unit that includes an adjustment strategy set for controlling water sharpening of the pulpstone. According to the adjustment strategy, the treatment pressure and/or the treatment interval of the sharpening water jet is controlled relative to an error value between the target quality value and the actual quality value of the fiber pulp. An associated apparatus is also provided.
