Bauxite Rotary Kiln Delivers To Argentina

This week, Baichy machinery workers loads a complete rotary kiln plant 1.8x16m to Argentina. Client wants to process bauxite ore. Rotary kiln is a type of rotary kiln equipment specifically developed for the calcination of bauxite. Here is an introduction to it:

Rotary Kiln Structure

1.Rotary part: The main body that rotates during operation, allowing the bauxite to move inside the kiln for uniform heating and calcination.
2.Supporting part: Supports the entire weight of the rotary kiln and ensures its stable operation. It usually consists of several sets of support pedestals or rollers.
3.Transmission device: Transmits the power to make the rotary kiln rotate at a designed speed. It typically includes a motor, gearbox, and transmission components such as belts or chains.
4.Kiln head and kiln tail: The kiln head is the end where the material enters the kiln, and the kiln tail is the end where the processed material exits. They are equipped with seals to prevent gas leakage and ensure the normal operation of the kiln.
5.Combustion device: Provides the heat source for the calcination process, usually using fuels such as coal, gas, or oil. The combustion device is designed to ensure efficient combustion and heat transfer.

Rotary Kiln Working Principle:

The bauxite enters the kiln from the higher end (kiln tail) of the cylinder. Due to the inclination and slow rotation of the cylinder, the material both rolls in the circumferential direction and moves in the axial direction from the higher end to the lower end (kiln head). During this process, the high-temperature gas generated by the combustion of fuel in the kiln provides heat, and the bauxite is continuously heated and undergoes calcination reactions under high-temperature conditions. As the calcination temperature increases and the holding time prolongs, the chemical and physical properties of the bauxite change, increasing the aluminum content and improving the grade.

Rotary Kiln Product Advantages:

1.Low energy consumption: Compared to some other similar equipment, it can reduce the unit coal consumption by a certain percentage, which helps to save energy and reduce production costs.
2.Easy operation: The technology is stable and reliable, requiring relatively few professionals to operate, which simplifies the operation and management of the production process.
3.Low environmental pollution: It has relatively low emissions and less impact on the environment, meeting the requirements of environmental protection.
4.High adaptability: It can use various fuels such as gas, pulverized coal, and fuel oil, which provides flexibility in the choice of fuel according to different production conditions and requirements.
5.Upgradeable to automated control: It can be equipped with an automated control system to make the operation more accurate and stable, improving production efficiency and product quality.

Bauxite Rotary Kiln Applications:

1.Aluminum production: The alumina produced by the bauxite rotary kiln is a key raw material for aluminum smelting. It provides the necessary aluminum oxide for the production of aluminum metal.
2.Refractory materials: It is used to manufacture high-quality refractory materials, which are widely used in the construction of high-temperature industrial furnaces, such as those in the steel, glass, and cement industries.
3.Other fields: Bauxite rotary kiln products can also be used in chemical intermediates production, as well as in some applications that require high-temperature resistant and wear-resistant materials, such as anti-skid protection and high friction surface treatment.
