In Rotary kiln The rotary kiln is more widely used and widely used. Of course, some problems cannot be avoided when using. For example, during the firing process, the fire in the kiln becomes larger. Therefore, in order to avoid the influence of the fire in the kiln on the products and the kiln itself, what should be done in this case?

 

1. When the rotary kiln is used, the amount of coal added in the preparation process is reduced. If it is coal stone, the quantity of stone decreases and the quantity of clay increases;

2. Speed up the edge of the edge, but this will lead to excessive black core volume;

3. Reduce the number of exhaust fans and side velocity formula, reduce the firing temperature of tunnel kiln, and change the formula as much as possible.

 

In the eyes of too many people, the kiln body of rotary kiln is parallel to the ground, but it is not the case. Generally, the inclination of kiln body and ground is about 4%, and the inclination is usually between 2.5% and 4.5% according to the filling rate of materials. Don't underestimate this tilt less than 5 degrees, it can greatly improve work efficiency. The design of kiln body is a combination of various disciplines. From a physical point of view, the inclined kiln body rotates faster and is easier to rotate at high speed, so that the material in the kiln is heated more. Uniform heating not only improves the efficiency of the rotary kiln, but also the temperature of the whole kiln tends to be uniform, thus prolonging the service life of the kiln.

Some people ask why the inclination angle of rotary kiln is not a fixed value but a range? What factors determine the inclination of the kiln? This is what we call the first stage, that is, the material filling rate, which is the first factor affecting the inclination of the kiln. If there are a lot of materials in the kiln and the filling rate is large, the rotary kiln will rotate slowly. For the sake of stability, the inclination angle of kiln is very small. On the contrary, the kiln material is less, the filling rate is smaller, the kiln body rotates faster and the angle is larger. Therefore, the rotational speed is also the key value affecting the inclination of the kiln.

Based on years of production experience, the manufacturer summarized the corresponding relationship between the kiln body inclination and material filling rate.

When the material filling rate is 13%, the inclination of kiln body is 2.5%. When the material filling rate is 12%, the inclination of kiln body is 3.0%. When the material filling rate is 11%, the inclination of kiln body is 3.5%. This is very good; when the material filling rate is 10%, the inclination angle of kiln body is 4.0%.

It has been proved that the inclination angle of the rotary kiln equipment is determined after the above-mentioned method, and the rotary kiln has high efficiency. If you can trust the experience of our factory, you can apply this method in your own production for your own convenience. Production use.
