The number of the grinding rollers is three, and the three grinding rollers are intermittently distributed, resulting in the toner sticking to the rollers, affecting the mixing, high viscosity, and uneven mixing. The three-roller grinder is equipped with scrapers at corresponding positions of the three grinding rollers. When the grinding rollers rotate, the scrapers will scrape the mixed material stuck to the surface of the grinding rollers to make the mixing more uniform. By twisting the turntable, the turntable will drive the screw to rotate and displace. Since the insertion rod at the scraper is movably inserted in the annular sleeve, the movement of the screw will drive the scraper to rotate with the insertion rod as the axis, thereby adjusting the distance between the scraper and the grinding roller.
