The rotary kiln from China professional manufacturer Henan Terbaik Machinery is designed for efficient processing and transformation of various materials. Here's a detailed overview of its working principle :
Structure and Operation
Cylindrical Vessel
Design: The kiln is a cylindrical vessel slightly inclined to the horizontal axis.
Rotation: It rotates slowly around its axis, facilitating the gradual movement of the material from the upper to the lower end.
Material Processing
Feeding: Materials are fed into the upper end of the cylinder.
Movement: As the kiln rotates, materials gradually move downwards, undergoing stirring and mixing.
Hot Gases: Hot gases pass along the kiln, either in the same direction (co-current) or, more commonly, in the opposite direction (counter-current).
Heat Source
External Furnace: Hot gases can be generated in an external furnace.
Internal Flame: Alternatively, a flame can be generated inside the kiln using a burner-pipe (or 'firing pipe').
Fuel Types: The fuel used can be gas, oil, or pulverized coal.
Key Features
Efficiency
Material Processing: The inclination and rotation ensure thorough mixing and gradual movement of materials, optimizing processing efficiency.
Heat Management
Counter-Current Flow: Usually, the hot gases flow in the opposite direction to the material, maximizing heat transfer efficiency.
Fuel Flexibility: The ability to use different fuel types (gas, oil, coal) provides flexibility and efficiency in heating.
Robust Construction
Durability: Designed for heavy-duty operations, the kiln is constructed to withstand high temperatures and continuous operation.
