Grinding device for processing thermal insulation coating

The utility model discloses a grinding device for processing a heat insulation coating, which is applied to the technical field of grinding devices and is characterized in that a first servo motor is arranged to drive a first grinding roller to quickly rotate in a grinding box through a rotating shaft, so that chippings and impurities clamped at the top of a screening mesh can be scraped off; the problems that the coating raw materials are clamped on the surface of the screening net, the screening net is blocked, and normal screening cannot be achieved are solved, and the screening efficiency of the screening net is improved; a second servo motor is arranged to drive a linkage chain to synchronously rotate through a driving wheel, and the linkage chain can synchronously transmit rotating power of the driving wheel to a first driven wheel, a second driven wheel and a third driven wheel, so that a second grinding roller and a third grinding roller rotate in a feeding box and preliminarily grind and smash coatin
