Based on grinding movements' analysis of pulping material in the BIVIS extruder, the paper has studied design theories of transport screws of the machine, and inferred relationship expressions of a flux rate of the pulping material and basic parameters of a mechanism of the twin screw extruder, and put forward a basic thoughtfulness of design for the BIVIS extruder.
在分析双螺杆磨浆机中物料磨浆运动的基础上 ,对双螺杆磨浆机的正向螺旋的设计理论进行了研究 ,建立了流量与双螺杆机构正向螺旋的基本参数之间的关系 ,提出了双螺杆磨浆机设计的基本思路。
