Blank deironing device for ceramic production

The invention relates to an impurity removal device, and discloses a blank deironing device for ceramic production. The blank deironing device for ceramic production comprises a box body, the top endof the box body is a feed port, a grid plate is arranged in the feed port, two transmission shafts are arranged below the grid plate, and a plurality of crushing knives are arranged on the two transmission shafts in a staggered manner; and a material falling plate is arranged below the crushing knives, a group of magnetic rollers are arranged below the material falling plate, a scraper is arrangedon one side of each magnetic roller and clings to the outer wall of the corresponding magnetic roller, a fixing plate is arranged below the scrapers, and a material falling plate B is arranged belowthe fixing plate. After a blank is primarily filtered through the grid plate, the blank is crushed through the crushing knives, then the blank is ground and refined through the magnetic rollers, meanwhile, fine iron slag in the
