摘　　要：实验研究了自同步概率筛主要工艺参数对筛分效率的影响度。文章以自同步概率筛筛分效率分析入手,探讨筛面振动频率、筛面振动幅值、筛面倾角等工艺参数与筛分效率之间的影响关系,获取了系统最佳运行工艺参数组,即:振幅3 mm时,筛分效率最佳;激振频率700-850 r/min时,筛分效率较好;给料速度分别为2.5 t/h和3.5 t/h时,对应筛网倾角21°和22°筛分效率较好。The influence of process parameters on the screening efficiency of a probability sieve was studied. The effects of sieve vibration efficiency, sieve vibration amplitude and sieve surface inclinations on the sieve screening efficiency were discussed via an analysis of the performance of a selfsynchronous probability sieve. An optimal process parameters set was obtained. The screening efficiency reaches the highest when the sieve surface vibration amplitude is 3 mm; The screening efficiency is considerably high when the sieve vibration frequency is in the range of 700 °850 r/min; The screen efficiency is similarly high when the feeding speed is 2.5 t/h and 3.5 t/h and the sieve inclination angles are 21 °and 22°.
