Bauxite rotary kiln is produced based on the properties of bauxite and combined with the advantages of traditional rotary kilns. It is a relatively commonly used calcining equipment. It has simple structure, high productivity, small footprint, low investment and operation costs, and good use effects. Excellent quality, deeply recognized and affirmed by users in the industry.

The discharge cooling of the bauxite rotary kiln equipment produced by XKJ GROUP uses a vertical cooler to replace the original cooling cylinder, which avoids the loss of sensible heat of the material. The hot materials falling from the kiln head are cooled by exchanging heat with the blown secondary air. The air absorbs heat and the temperature rises and then enters the rotary kiln to support combustion. A vertical preheater is installed at the end of the kiln to increase the temperature of the material. The waste heat of the flue gas is directly transferred to the material, and the flue gas temperature can be lowered to below 235°C, effectively recovering the heat taken away by the exhaust emissions, and also reducing the negative pressure for subsequent dust removal.

The 3.1-meter-diameter bauxite rotary kiln is simply introduced in the following two ways:
Air intake into bauxite rotary kiln
The bauxite rotary kiln is divided into primary air and secondary air with the help of combustion air. The primary air directly participates in combustion, and the secondary air is cooling air. Primary air and secondary air are supplied by separate fans. This design allows the secondary air temperature to rise to over 600°C and serves as combustion-supporting air, providing favorable conditions for saving fuel; and a combustion system is used to supply heat to the rotary kiln. In addition to using pulverized coal as fuel, low calorific value gas (such as generator gas, calcium carbide tail gas, semi-coke gas) can also be used as the calcining fuel alone, or a variety of fuels can be used at the same time. The calcination temperature can be adjusted by adjusting the flow of air and gas.

Advantages of 3.1m diameter bauxite rotary kiln
1. The structural design of the bauxite rotary kiln equipment is very novel, so it operates stably during the working process and has low noise. It is a calcining equipment with low energy consumption and good environmental protection at this stage.
2. The production capacity of the bauxite rotary kiln is about 5 times that of the traditional one. High-yield equipment can bring more economic benefits to users. Such equipment will be easily favored by users, so its overall sales volume is high.
3. The bauxite rotary kiln can filter out impurities in the bauxite mineral material, so after being processed by the equipment, its purity is very high. Therefore, the calcining accuracy of the equipment cannot be compared with other equipment.
