Working Principle of Rotary Kiln
Material Feeding & Movement
Raw materials are introduced at the start of the kiln through a conveyor. The kiln is slightly inclined (2–4 degrees), pushing materials downward due to gravity. The rotational movement (0.5–3 rpm) ensures continuous mixing and uniform exposure to heat.
Heat Transfer & Processing
Heat transfer plays a crucial role in material processing. A burner system at the discharge end generates extreme temperatures (up to 1450°C). The heat is circulated through conduction, convection, and radiation, ensuring the required heat for material processing or chemical reactions.
Chemical Reactions in Different Zones
As the material circulates through the kiln, it experiences sequential chemical reactions in separate zones:
Drying Zone
Moisture evaporates from raw materials.
Preheating Zone
Volatile compounds start to crack down.
Calcination Zone
The core processing phase where extreme temperatures trigger reactions like decomposition, sintering, or phase transformation.
Cooling Zone
The processed material slowly cools before departure to prevent thermal shock.
Material Release and Waste Gas Management
The processed product is discharged at the end of the kiln, where it is managed for further processing, storage, or packaging. Meanwhile, exhaust gases are directed through dust scrubbers to lower emissions and optimize power efficiency.
