The results showed that soft straw could be directly fed into the smashing device without cutting with the average efficiency of 1.27 kg/h and electricity consumption o per ton of 32.0 k W·h.The hard straw with high fiber should be first fed into the shredding device with force feeding roll to cut and then grinded, for which the efficiency average was 0.67kg/h and electricity consumption per ton was 60.5 k W·h. The machine was stable,safe and reliable with strong adaptability of materials and no-dust operating environment, which satisfied the design requirements.展开更多
