How To Adjust The Fan Air Volume Of Raymond Mill

2022-06-07

The Raymond mill itself has a damper tube, and the switch of the damper can control the air volume of the fan of the Raymond mill. This valve is a single-hinge single-plate valve, and the rotation angle is generally adjusted within the range of 45 degrees. When the air door is opened wide, that is, the air plate is along the horizontal direction of the pipeline, the air volume of the Raymond mill fan reaches the maximum, and the more the powder is milled at this time. thick. When the air door is small, that is, the air plate approaches the vertical direction of the pipeline, the air volume of the Raymond mill is reduced, and the powder is fine.
Install a frequency converter or use a speed-regulating motor for the motor of the Raymond mill fan. The air volume of the fan can be controlled by adjusting the speed of the fan, and then adjusting the speed of the fan motor. The disadvantage of installing a frequency converter and a speed-regulating motor is that the cost is high.
Replacing the motor pulley of the fan of the Raymond mill is more troublesome than installing a frequency converter, and can only change one speed. The advantage of this method is that it saves money, but the disadvantage is that only one speed can be changed, but the air volume can be adjusted by the damper. This method is used by most people. It is mainly used to increase the air volume of the fan of the Raymond mill and increase the air volume of the Raymond mill.
