Zusammenfassung:The invention discloses an anhydrous gypsum grinding and refining process which comprises the following steps: step 1, gypsum blocks are conveyed into a treatment box through a conveying belt of grinding equipment, and the gypsum blocks are conveyed into a shielding box, and the invention relates to the technical field of gypsum processing. According to the grinding and refining process for the anhydrous gypsum, shots sprayed by the shot blasting mechanism impact and crush gypsum blocks, blasting shots and gypsum powder conveyed by the conveying belt fall above the filter screen, the gypsum powder leaks down along the filter screen, the blasting shots are blocked, the push plate rotates in a reciprocating circulating mode, and through the arrangement of the interval grooves in the filter screen, the gypsum blocks are ground and refined. The blast shots are continuously stirred, so that gypsum powder falls down from the filter screen, the push plate rotates clockwise, the blast shots are pushed to enter the fi
