Design of 9LRZ-80 Vertical Straw Rubbing and Cutting Machine

To overcome the disadvantages of straw cutter and chopper and remain their advantages, quite a new type of straw roughage processing machine——9LRZ-80 Vertical Straw Rubbing and Cutting Machine was developed. Its designing principles, structure, function, technical specifications and performance of the machine were described in detail in this paper. Testing results showed that it combines the performance of cutter and chopper into one and has the advantages of high productivity, low energy consumption, stable working performance, safety, wide suitability of processing material and good processing quality.
