What do the filling rate and inclination in the rotary kiln mean?

Rotary kiln is a large-scale building material equipment that can process various materials such as cement, lime, kaolin, etc. for calcination, and the finished product is of good quality. Many users often mention the filling rate of the rotary kiln and the inclination of the kiln body when purchasing a rotary kiln. What is the relationship between the two?
For users who are new to this industry, especially those who have inspected the rotary kiln project, have they found that the rotary kiln body is placed parallel to the ground or placed at an angle? If your answer is to place it at an angle, it means you have I know this project very well. Whether it is a lime rotary kiln or a cement kiln, the kiln body is not placed parallel to the ground, but has an inclination of <5°, and the inclination is generally between 2.5%-4.5% according to different material filling rates.

Why is the rotary kiln placed so inclined? From a physical point of view, the inclined kiln body rotates faster and is easier to rotate at a high speed, so that the materials in the kiln are heated more fully. The uniform heating of the materials speeds up the production efficiency of the calcined materials to a certain extent, and the uniform heating not only improves the efficiency of the rotary kiln, but also the temperature of the entire kiln body tends to be consistent. It also effectively prolongs the service life of the kiln body and creates a better for the enterprise. Recovery of benefits.
So what is the relationship between it and the filling rate? The relationship between the two is extraordinary! The filling rate of the rotary kiln material directly affects the inclination of the kiln body. If there are more materials in the kiln and the filling rate is larger, the rotary kiln will turn slowly. For the sake of stability, the inclination of the kiln is smaller. Conversely, there is less material in the kiln, lower filling rate, faster rotation of the rotary kiln, and greater angle.
