The working principle of Three Roll Grinding Mill

The working principle of Three Roll Grinding Mill is: when the three-roll grinder is working, the three rollers are driven by the transmission device to realize slow, medium and fast rotation with a certain speed ratio. In the Three Roll Grinding Mill, because the rollers rotate toward each other, and there is a pressure and speed difference between them, the poorly dispersed materials are also squeezed and sheared by the rollers. The material is firstly rolled between the middle and slow rollers, and then enters the gap between the middle and fast rollers to continue grinding, and is finally covered on the fast rollers and scraped off by the doctor blade. In order to achieve uniform grinding, the material usually needs to be ground 2 to 3 times. The grinding fineness can be measured by the fineness plate. Generally, the grinding fineness of the slurry should reach more than 50um.
