摘　　要：振动旧砂再生是干法再生中机械法的一种形式,本文通过正交试验等方法研究了中心筒体、介质、再生时间、激振力等工艺参数对湿型/树脂混合旧砂振动再生的影响。试验结果表明:设置中心筒体、加入介质可以提高振动再生机的再生效果;影响旧砂再生含泥量效果的因素由大到小的次序为:时间、激振力、钢球直径、砂与钢球配比。通过试验得到了旧砂振动再生优化的工艺参数。本试验结果对设计振动再生机和优化振动再生工艺具有指导意义。Vibration type reclamation is a type of mechanical method of regeneration.The influence of central cylinder,media,time,exciting force and other parameters on the vibration type reclamation was studied by the orthogonal experiment method.The experimental results show that setting central cylinder and adding media can improve the effect of reclamation of used sand,The influence order of the factors from big to small is time,exciting force,ball diameter and sand and the ball ratio.We can get the optimized process parameters of vibration type reclamation by the orthogonal experiment method.The results of experiment are of guiding significance to design of vibration regeneration machine and optimization of vibration type reclamation process.
