A system and method for monitoring and control operation of a rotary disk refiner (32a). A characteristic of the stock such as temperature is monitored by a sensor (70) to a parameter, such as dilution water, feed screw speed and/or refiner gap to keep some variable substantially constant, close to a setpoint, within a range of the setpoint, close to a setpoint profile based on a distribution of the characteristic over the refining zone or a setpoint profile range. Refiner disk bar angle can be optimised to reduce refining zone temperature and energy use. Thereafter, the control method can be employed. One control method attempts to keep specific energy substantially constant by keeping a ratio between load and production substantially constant. Load is kept substantially constant by regulation of dilution flow to keep refining zone temperature substantially constant. The feed screw is regulated to keep production substantially constant.
