Experimental research on microcrystalling processing of potassic shale
Abstract：The potassic shale was microcrystally processed by a WJH-1. The characteristics of samples at different processing time were characterized by a laser size distribution apparatus, specific surface area instrument, SEM and XRD. The changes of particle size distribution, in- cluding ds0 and d97, and the changes of specific surface area and crystal lattice were analyzed. The results show that the exponential decrease of ds0 and dgz with time is achieved. The extent of decrease in the prior 1.5 h is max, the dso decreased by 80. 07~ and dgz 79. 68~. The spe- cific surface area increases firstly, decreases soon after and then increases slowly. A better fit- ting between specific surface area and energy consumption was completed using a quartic poly- nomial. The lattice distortion occurred, the degree of crystallization is reduced and microcrys- tailing processin~ has been take nlsee
