22-01-2015  Pulp refining or beating could be described as a mechanical treatment of the pulp by using the special equipment (refiner). Nowadays the term “refining” is more common than “beating” in the studies because of the appearance of different refiners which are widely used in the pulp industries. However both phrases have same meaning.

Low Consistency Refining of Softwood Chemical Pulp ver 2

The refiner speed was adjusted to the desired speed (i.e, 1200rpm) then the refiner gap was changed from 9.0 to 2.5 mm to measure no-load power. It was observed that there is almost no change in power consumption (no refining of fibers) if the gap size between plates of the refiner is greater or equal than 2.5 mm, so the power related to

Impact of pulp consistency on refining process

Each experiment started with the determination of the no-load power (measured for the refiner working with the pulp and maximum refiner gap opening). A heat exchanger was used to cool the pulp slurry such that refining did not exceed 35 o C. A single volume of refined pulp was set at 130 dm 3.
