双螺杆磨浆机螺旋转子的研究与开发

双螺杆磨浆机将在高浓制浆领域得到越来越广泛的应用，螺旋转子是双螺杆磨浆机的核心零部件，对其进行优化设计和耐磨性处理是发挥双螺杆磨浆机优良磨浆性能的关键工作。由于不同遣纸原料的预处理方式和磨浆要求不同，造成螺旋转子的结构设计存在差异性，因此，我们必须有针对性的分析造纸原料的生产特性和螺旋转子的失效形式，通过理论与生产实践相结合的方式，研究和开发高性能的螺旋转子来满足生产需求。

The research and development of the spiral rotor of BIVIS extruder

BIVIS extruders are going to be applied extensively in the high concentration pulping process and the optimum design and wearresistance treatment of the screw rotor, which is the core part of the BIVIS extruder, are the key to apply the superior refining performance ofBIVIS extruder. Because of the difference in the structure design of the screw rotor due to refining pretreatment modes of paper making rawmaterials and different refining requirements, the characteristics of paper making raw materials and invalidation forms of the screw rotor mustbe analyzed specifically in order to research and develop high-performanced screw rotor for the production demand via combining the theoryand production practice.
