Product Details:

We are well known manufacturer of the wide range of Dolomite Calcination Plant with two cyclone separators and allied accessories. Made by using high grade raw materials, these are produced in our latest technology laden production unit. Our machines are well capable of reducing the consumption of oil to 50% and black ash. With all international specifications in place, these machines are of highest quality.

Product Details:

A bauxite rotary kiln plant is an industrial facility designed for the thermal processing of bauxite ore—primarily to produce calcined bauxite, which is used in various refractory, abrasive, and metallurgical applications. The process involves the use of a rotary kiln, a long cylindrical rotating furnace, where bauxite undergoes high-temperature calcination.

Description of Bauxite Rotary Kiln Plant 1. Raw Material Handling

• Bauxite ore (typically containing Al₂O₃, Fe₂O₃, SiO₂, and other minerals) is received and stored.

• It is crushed, screened, and sometimes washed to remove clay and other impurities.

• Materials are fed into the system via conveyors or hoppers.

2. Preheating Section

• The bauxite may pass through a preheater (cyclone or suspension type) where it's partially heated using kiln exhaust gases.

• This step improves thermal efficiency and reduces fuel consumption.

3. Rotary Kiln

• A refractory-lined rotating cylinder inclined slightly to allow material flow by gravity.

• The kiln is heated externally using coal, oil, gas, or electric burners.

• Bauxite is calcined at temperatures typically around 1,200–1,600°C, depending on the final application.

• Chemical and physical changes:

  • Removal of water (dehydration)

  • Phase transformation of alumina compounds

  • Removal of volatile impurities

4. Cooling Section

• Calcined bauxite is cooled using an air or water-based cooler (rotary or grate type).

• Cooling improves material handling and allows for heat recovery.

5. Product Handling

• The cooled calcined bauxite is sent to storage silos or packed for transport.

• It may undergo further screening to obtain specific size fractions.

6. Air Pollution Control

• Off-gases are treated using bag filters, electrostatic precipitators (ESPs), scrubbers, or cyclones.

• Dust and VOCs (volatile organic compounds) are minimized to comply with environmental standards.
