Structural advantages of rotary kiln

Rotary kiln is a rotating cylindrical vessel which is used for drying, calcination and sintering in a continuous process with the use of hot gases. The hot gases may be generated in an external furnace or by a flame inside the kiln. Our cement rotary kiln and lime rotary kiln has been developed for performing drying, calcination and sintering work in a continuous process. Widely used for cement, lime and other materials, it uses hot gases for the operation. Integrated with variable speed drive, process automation and instrumentation, this kiln ensures optimum operational control. In addition to technology, its design features better inlet and outlet sealing to ensure minimum false air entry.



Better inlet and outlet sealing to ensure minimum false air entry

Hydraulic thruster provides control to the Kiln axial movement.

Three support roller stations are provided for better distribution of forces on shell.

Ensures optimal safety with regard to material elasticity at operating temperature.

Throat adjuster is provided to optimize Kiln / Calciner fuel.



Kiln inlet seal will be of friction type ring. The sliding ring have pneumatic cylinders, distributed equally on the periphery, which always keep both the shoe rings of primary seal in contact, even during and upward-downward movement.


Discharge end seal is made up of radially placed overlapping segmented graphite blocks. This allows movement of shell in radial and axial direction while effectively sealing.


The discharge end is provided with another annular shell around with spacer flexible element. The cooling air is blown in this annular gap by cooling air fan using distribution nozzle ring made of pipes.
