The kiln body of the rotary kiln is placed parallel to the ground in the eyes of too many people, but it is not. Generally, the rotary kiln body and the ground have a slope of about 4%, and the inclination is generally between 2.5% and 4.5% depending on the material filling rate. Do not underestimate the inclination of less than 5 °, it has a greater improvement in the efficiency of the rotary kiln.

 

   The design of the rotary kiln is a combination of various disciplines. From a physical point of view, the inclined kiln body rotates faster and is easier to rotate at a high speed, so that the material in the kiln is more heated. Uniform heating not only improves the efficiency of the rotary kiln but also the temperature of the entire kiln body tends to be uniform, prolonging the service life of the kiln.

 

   Someone asked why the kiln of the rotary kiln is not a fixed value, but an interval. What factors determine the slope of the kiln? This is the first paragraph we said, material filling rate, which is the first factor affecting the inclination of the kiln. If there is more material in the kiln and the filling rate is larger, the rotary kiln will turn slower, and the inclination of the kiln is small for stability. On the contrary, the material in the kiln is small, the filling rate is small, and the rotary kiln rotates faster and the angle is larger. Therefore, the rotational speed of the rotary kiln is also a key value that affects the inclination of the kiln.
