Pneumatic Corn Milling Machine Roll Clearance Adjustment

CORN MILLING MACHINE 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 corn milling machine 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.

The hand wheel for corn milling machine roll clearance adjustment has dial that can indicate roll clearance adjustment situation. On the dial, there have black and red indicators, which indicate the smallest roll clearance and the corresponding position of the working roll clearance. When we install the smallest corn milling machine roll clearance, we don’t need to start the motor. Instead, we just need to connect the air source to make the equipment stay in the closing situation. We adjust by the adjusting nuts and the corn milling machine roll clearance adjustment hand wheel. Then, we can fix the black indicator position.

The round corn milling machine roll clearance adjustment of each system can refer to the following data: 1B (0.7MM), 2B (0.4mm), 3-5B (0.3MM), smooth roll (0.3mm). When we adjust the corn milling machine roll clearance, we should observe the relationship between the red indicator and the black indicator on the dial and avoid too small roll clearance which may cause two rollers to touch and damage corn milling machine performance.
