The rotary kiln is mostly employed in ways mineral processing operations. Most of the companies often use advanced rotary kiln models that are designed for the first principle in order to evaluate the design of the individual customers. However, this has become one of the essential tools that are equally applicable to different applications such as nickel laterite, nickel carbonate, spodumene (lithium) and pyrometallurgical production.
Working of Rotary Kilns
Rotary Kilns well known as rotary calciners or furnaces are technically used in thermal treatment processes, including sintering, calcination, firing and more. However, each of the treatment is unique that can be applied to suspensions, powders, granules and even green bodies. Perhaps the rotary kiln consists of different body parts like rotating unit, the cylindrical section and outlet housing. When it is constantly subjected to its functioning all the materials mix up well, thereby subjected to heat depending upon the application.
Optimising of its operation and maintenance
There are in fact many different service products used in order to optimise the availability of the rotary kiln. In addition to that, all these rotary kiln services will significantly help in the overall operation of a kiln that is also included in the girth gear fastening section, the tyre fastening system as well as sealing. However, this will help in improving the productivity of the plant, thereby making it more efficient and effective. In addition to that it also offers hidden optimisation potential to uncover and exploit:
- Helps in improving the overall product quality, thereby reducing the production cost.
- Increases uptime and also optimises the product life cycle.
- Also increases the production volume and also reduces the range of spare parts.
- Low maintenance as well as reduced cost of repair and replacement.
The Rotary kiln applications
There are many applications associated with a rotary kiln and will also help in benefiting the thermal process. And are given as follows,
Thermal Desorption
It is a process that utilises heat to increase the volatility of contaminants that helps in removing solid matrix from different materials. The volatilised contaminants can even be collected or thermally destroyed. As the flames never have a chance to get in contact with the material the overall application is processed using an indirect rotary kiln.
Drying
Well, the rotary kiln also finds its application in dry bulk materials. The indirect heat rotary kiln is especially used for finely dividing the materials, dusting, and low to temperature applications. The rotary kiln dryers are the special machines that are used in the drying process giving you a wide variety of applications.
Calcination
It is a process involved in the heating of solids to a certain temperature for the purpose of illuminating the volatile substances, oxidising a portion of the mass, or rendering them friable. However, this is involved and is more concerned with the process of purification.
Therefore, all these comprehensive ranges of services truly help in optimising the rotary kiln. The overall process can accomplish in acquiring the desired material based on the applications. They are both independent and a part of the existing rotary kiln control system.
