DAL MILL PLANT roll clearance adjustment is completed during the equipment working process. During this process, the lower part of the slow roller bearing arm is locked by the clutch brake drive cylinder. During the equipment working process, we can adjust the dal mill plant roll clearance by the roll clearance adjusting hand wheel and learn about the adjustment situation from the dial of the hand wheel. For example, when the hand wheel takes a turn, the roll clearance variation is about 0.2mm.
