摘　　要：根据旧砂表面的惰性膜在剪切力的作用下最容易去除这一原理，设计并制做了用于旧砂再生的螺旋振动再生试验机．用此机再生水玻璃砂和树脂砂，均达到再生砂质量要求．理论分析也充分说明，当转速为１７００ｒ／ｍｉｎ时，抛料指数为最佳值，此时激振力最适宜，再生效果最好．According to the principle that it is the easiest way to eliminate the inert film on the surface of old sand by shearing stress a spiral vibrating sand reclaimer is designed and made.This machine can be used to reclaim sodiumsilicate sand and resin bonded sand,both coming up to the quality standard of reclamed sand.The theoretical analysis shows that when the rotating speed reaches 1700r/min,the throwing index number and the exciting force as well as the result of reclamation will be optimum.
