[0039] The use method of the dust-free activated carbon grinding device of the utility model is as follows: first, calcium carbonate is added to the inside of the collecting cover, and then the cover plate 4 is covered to the grinding cylinder 1, and the first driving motor is started. The output end of the first driving motor drives the transmission rod to rotate, and the transmission rod drives the grinding roller to rotate. The grinding roller cooperates with the filter plate to grind the calcium carbonate. The ground calcium carbonate flows out to the inner bottom wall of the grinding cylinder through the filter plate. The transmission rod rotates and drives the scraper, the bottom stirring blade and multiple stirring blades to rotate. The scraper can scrape off the calcium carbonate attached to the bottom and side wall of the grinding cylinder to reduce the adhesion of the ground calcium carbonate to the bottom wall of the grinding cylinder. The scraper is triangular. When the transmission rod rotates, it drives each stirring blade to rotate. When each rotating blade is subjected to resistance, it will push the second support rod in the bearing, so that the rotating blade rotates more smoothly. The calcium carbonate in the grinding cylinder is stirred to make the calcium carbonate better dispersed, which is convenient for screening and secondary grinding. When the transmission rod rotates, it drives the bottom scraping blade to rotate, and the bottom scraping blade discharges the calcium carbonate from the discharge port.

[0040] The discharged material flows into the feed funnel, and the second drive motor is started. The output shaft on the second drive motor drives the drive mechanism to rotate, and the drive mechanism drives one of the transmission rollers to rotate, and the transmission roller drives the transmission belt and the transmission plate to rotate. When the transmission plate moves the calcium carbonate upward through the discharge pipe, it is discharged into the collection cover through the discharge pipe for secondary grinding, and the grinding is more fine.
