Coal Pulverizer at Best Price in Mandi Gobindgarh, Punjab

Coal pulverizer. Raw coal is fed through a central coal inlet at the top of the Coal pulverizer and falls by gravity to the rotating grinding table, mixing with classifier rejects returned for re-grinding. Centrifugal action forces the coal outward to the grinding ring where it is pulverized between the ring and three grinding rollers. Grinding load,
