As the rotating pile rotates, the gear lever moves the spring to squeeze the gas inside the air bag into the inside of the rotating pile, so that the hollow square pile descends. As the hollow square pile slowly descends, the grinding disc moves downward, grinding the coal from large to small and finally into powder, thereby achieving the effect of conveniently grinding the coal into powder.

[0012] (2) In the coal testing crushing and grinding device, after the hollow square pile is lowered to a certain position, the gas inside the air cavity will enter the interior of the hollow square pile and then be ejected from the grinding sheet to cool the coal powder being ground.

[0013] (3) In the coal testing crushing and grinding device, when the gas is discharged through the grinding disc, it passes through the cleaning mechanism, causing the sealing plate to drop, and then blows the fan blades to rotate, causing the stirring rod to rotate and drop, loosening the coal debris at the exhaust position of the grinding disc to prevent it from getting blocked.

[0014] (4) In the coal testing crushing and grinding device, the gear lever periodically moves the air bag, thereby exhausting all the gas inside the air bag at one time. The gas is quickly squeezed out and can turn over the coal debris at the bottom of the grinding plate, so that it is ground in all directions and the exhaust port of the grinding plate is not easily attached with coal powder.
