The ball mill trunnion is located at both ends of the ball mill cylinder and plays the role of supporting and connecting the mill cylinder. Two ball mill trunnions are installed at both ends of a ball mill, one is the feed trunnion, which is the passage for the material to be transported into the cylinder, and the other is the discharge trunnion, through which the …
With a production capacity of 100 to 1200t/d, the material is fed into the preheater's top storage bin via a discharge chute. Simultaneously, the high-temperature flue gas introduced by the rotary kiln heats the material to over 1000°C, causing partial decomposition of the limestone. Hydraulic push rods sequentially push the material into ...
