| 摘 要： | 应用ＳＫＲ－８０型砂磨机，对多种催化裂化催化剂物料进行了砂磨试验，找出了沸石结晶度、粒度等物料性质在砂磨过程中的变化规律。并着重考察了待磨催化剂的耐磨强度、流量等对磨后粒径的影响，获得了一些微球物料的砂磨曲线。从而为工业生产采用砂磨机提供了一定的试验依据。

| Abstract: | Various FCC catalysts and relevant materials were ground by using SKR 80 sand grinder. The changes of zeolite crystallinity and particle size during grinding were found. Effects of catalyst attriction index and slurry flow rate on after grinding particle size were specially investigated, and sand grinding curves of some FCC catalysts were obtained. These preliminary data can be used for commercial scale up. |
