<p>A double disc refiner apparatus (10) and associated method, in which two counter-rotating refiner discs (26, 28) which define a refining zone (58) therebetween, are counter-rotated at different steady-state speeds, such as 1800 rpm and 1200 rpm. For energy-efficiency, the feed end disc (26) is rotated at a faster speed than the control end disc (28), but in some instances, desired refiner output quality can be achieved by rotating the control end disc faster than the feed end disc.</p> |
