Then,we introduced sorts of waste equipments,sorts of driving,material framework and working theory,At last,we discussed the designed and caiculated way of cylinder screening machine of living waste. We established three-dimensional simulation of sorted machine adopting UG,and optimized framework of the machine.Key words:Living waste Cylinder Screening Sorted Machine design2
