摘要
通过对研制生产的９Ｒ－４０型揉碎机的揉碎机理和性能进行综合分析，并运用正交试验方法，对影响机具揉碎性能的一些主要参数作了定量研究，为该机的改进设计和使用提供了可靠的理论依据。
According to the method of orthographical test ,the rubbering theory and function of 9R-40 rubber were analysed syntheticaly.The main factors that affected the function of rubber were quantitively studied. It provided theoritical basis for improving designing and using rubbers.
