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. At the same time, pulps produced at higher refiner speed have higher strength properties and lower shives contents. There is little change of optical properties of the pulps.

结果表明:小叶桉物料在相同条件下进行汽蒸、挤压和化学预浸渍后,分别采用3500 r/min和4000 r/min的盘磨转速进行第一段磨浆,浆料磨至游离度670 mL时所需磨浆电耗与3000 r/min时的相比,分别下降16%和27%;浆料中纤维含量分别降低20%和35%;第一段磨后浆料再分别经相同盘磨转速(3000 r/min)的后续磨浆后,与相近游离度的浆料性能比较可知,随第一段磨浆盘磨转速的提高,浆料的细小组分含量略有增加,纤维含量显著降低,强度性能有不同程度的改善,但光学性能变化不显著。
