Abstract
Disc refiner is the key equipment in pulping and papermaking process, and the no-load power of disc refiner will directly affect the refining efficiency. So the refining efficiency and energy saving of the refining process will be promoted through theoretical and experimental study on it. In this paper, the measurement and the theoretical calculation method of the no-load power of disc refiner in low consistency refining were summarized. And the effects of pulp properties, control parameters and bar parameters of refining plate on no-load power were analyzed. The main research direction of the no-load power of disc refiner was proposed which has a positive significance on energy saving and pulp quality improvements of refining process.
