 · The size of a rotary kiln is not only a function of capacity, but also of the amount of heat which can be generated inside the rotary kiln from the volatizing and/or combustion of the material. The diameter and length of the rotary kiln are calculated based on the maximum feed rate, the required retention time, and what the bed profile (how full of material is in the rotary kiln) is required ...

The MKMSystem is an online measuring system for rotary kilns with more than 2 Stations to detect abnormalities during operation, which can lead to mechanical failures. The main objective is to detect thermal or permanent cranks in the kiln shell, loss of relative movement on kiln tires and problems in axial movement at an early stage.

Whether you are using a rotary dryer, rotary kiln, or rotary cooler, there is one thing that all these instruments have in common: they all use methods of heat transfer to carry out their transfer is how heat moves from one source to another. Understanding the types of heat transfer, and how they differ, is an important part in understanding how a rotary dryer, cooler, or kiln works.
