Working Principle Analysis of Rotary Kiln

Author:


Rotary kiln is a kind of long and inclined cylinder equipment, which is mainly composed of back push plate, furnace door and furnace roof. During the working process of the rotary kiln, the material enters the cylinder from one end and gradually moves to the other end with the rotation of the cylinder. In the whole process, the material is subjected to continuous hot air and radiant heat, and the material is dried, calcined and pyrolyzed.
The working principle of rotary kiln mainly includes the following aspects: first, heat energy transfer, which transfers heat energy to materials through hot air and heat transfer of cylinder wall; Secondly, material heat transfer, material releases moisture or gas after being heated in the cylinder, and absorbs heat for heating or pyrolysis reaction; Secondly, material mass transfer, material produces complex physical and chemical changes such as heat transfer and mass transfer in rotary kiln to complete various heat treatment processes; finally, the gas transfer, hot air through the cylinder and the flow between the material heat transfer and mass transfer process more smoothly.
In general, the rotary kiln through continuous rotation and heating, so that the material at high temperature to complete a variety of chemical changes and heat treatment process. Its working principle is complex and precise, which provides important support and guarantee for the production of various industries.
