| Popis: |
Paper and board making stock is refined in order to produce the properties needed in the manufactured product. Experiments using bleached softwood and bleached hardwood sulphate pulps have shown that particular values of paper breaking length can be obtained by different combinations of values of the power applied to the refiner and the mass flow rate of stock through it. The total specific refining energy used, however, is very dependent on the combination and can differ by more than 30%. In practice, the power and mass flow rate also have to satisfy other requirements, such as the ability of the pulp to receive the power and the time available to process a tonne of pulp. With proper control refining energy could be saved in many mills; a targeted saving of 10% is realistic. |
