[0002] The grinding part of the medium-speed roller-disc coal mill consists of a rotating grinding ring and three fixed and rotatable grinding rollers rolling along the grinding ring. The raw coal to be ground falls from the central coal drop pipe of the mill onto the grinding ring. The rotating grinding ring uses centrifugal force to move the raw coal to the grinding raceway and grinds it through the grinding rollers. The three grinding rollers are evenly distributed on the grinding disc raceway along the circumferential direction. The grinding force is generated by the hydraulic loading system and is evenly applied to the three grinding rollers through a statically determinate three-point system. This force is transmitted to the foundation through the bottom plate after passing through the grinding ring, grinding roller, press frame, pull rod, transmission plate, reducer, and hydraulic cylinder. The raw coal is ground and dried simultaneously. The primary air evenly enters the surrounding of the grinding ring through the nozzle ring, dries the coal powder mixture tangentially thrown out from the grinding ring after grinding, and transports it to the separator on the top of the mill for separation. The coarse powder is separated and returned to the grinding ring for re-grinding, and the qualified fine powder is taken out of the separator by the primary air.
