自七十年代以来,我国就开始研制和推广运用具有弹簧调压机构的碾轮混砂机,了解这种新型混砂机的关键在于弄清碾压力与砂层压实比(体现了碾压后的砂层紧实度)以及所混制的型砂性能之间的关系。先后两年在 SIIIOS 实验混砂机上作了这方面的试验研究,共混碾了五十余盘型砂,取得了一些数据和 Since 1970s, our country began to develop and popularize the use of a roller mill with a spring-regulated mechanism. The key to understanding this new type of mixer is to understand the ratio of roller compaction to sand compaction Pressure sand layer compaction) and the relationship between the mixed sand performance. Successively two years in the SIIIOS experimental sand mixer made this experimental study, blending more than 50 disc sand, obtained some data and
