Introduction

This article will teach you how to raise the ball mill temperature when the fresh air damper is closed. This is important because it will help prevent oxidation of the steel balls in the ball mill.

Problem: Ball Mill Operating at Low Temperatures

When the fresh air damper is closed, the ball mill temperature can drop below the dew point. This can cause condensation on the inside of the mill and a decrease in mill efficiency.

There are several ways to address this problem. One solution is to open the fresh air damper slowly while maintaining a constant speed. This will allow the ball mill to warm up gradually, and will maintain its efficiency.

Another solution is to use an auxiliary heater to heat up the ball mill enclosure. This will help to prevent condensation from forming and will increase mill efficiency.

Solution: Fresh Air Damper Closed and Air Venting

There is a common problem with ball mills where when the fresh air damper is closed, the exit ball mill temperature can be too low to produce good results. The solution to this problem is to open the air vent and allow the warm, circulating air to reach the mill. This will raise the ball mill temperature, and you will be able to produce good results.

Conclusion

In order to raise the exit ball mill temperature when the fresh air damper is closed, you will need to open the furnace door and allow more air into the plant. This will increase the ambient temperature and cause the ball mill to operate at a higher speed.
