摘　　要：在分析机筒衬套沟槽槽深、螺杆螺槽槽深和加工物料粒径关系的基础上,建立了沟槽机筒单螺杆挤出机3种常见的固体输送段产量粒径模型,该模型可用于研究机筒衬套沟槽槽深、螺杆螺槽槽深和颗粒物料粒径对固体输送机理的影响并定量计算沟槽机筒单螺杆挤出机固体输送段产量。此外,通过不同的机筒和螺杆组合及不同粒径的原料在自制的在线模拟试验机上对该模型进行了验证和试验分析。Based on the relations of the depth of helical barrel groove, the depth of screw channel and the particle size of materials, three common particle-size models were built to study the effects of the above parameters on solid conveying mechanism and to accurately calculate the output of single screw extruder with grooved barrel in solid conveying zone. Besides, the model is verified by experiments using different combinations of barrels and screws, and different particlesizes of materials with the online simulation testing machine.
