Results showed that, the specific refining energy consumption is decreased with increment of rotation speed of the primary refiner. At freeness level of about 670 mL CSF, for example, the specific refining energy consumptions is 363 kWh/t o.d. at 3000 r/min, and 305 kWh/t o.d. at 3500 r/min, which is equivalent to 16% energy saving, furthermore the specific energy consumption is only 265 kWh/t o.d. at 4000 r/min, which means 27% less refining energy required.
