[0043] Step 2: The polished gypsum powder enters the transport box 4 through the pipeline, the second motor 8 is turned on, and the output end of the second motor 8 rotates to drive the spiral feeding roller 7 to rotate upward, thereby transporting the gypsum powder to the right end of the transport box 4 and then falling into the drying box 9 through the pipeline, the drying box 9 and the third motor 13 are turned on, and the output end of the third motor 13 rotates to drive the agitator 11 to rotate, so that the gypsum powder is heated evenly, and the dried powder is discharged out of the box through the discharge pipe 14, thereby completing the drying of the gypsum.

[0044] Compared with the related art, the gypsum drying device for fire retardant coating production provided by the present invention has the following beneficial effects:

[0045] The output end of the first motor 26 is rotated to drive the long rod 23 and the short rod 31 to rotate, thereby driving the cutting blade 25 and the grinder 36 to perform primary crushing and secondary grinding on the gypsum block.
