Rotary Kiln Cement Plant Manufacturer

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.

CPG supplies a special range of small and medium capacity Rotary Kilns across the world with numerous applications.

Our design & production experts provide high quality, innovative & cost effective solutions according to the requirements of customers.

Kiln Inlet Seal

Kiln inlet seal will be of friction type ring. Two nos. rings, carrying wear shoe segments on face, with one ring being rotating with Kiln, slide on face to face. The wear shoes are lubricated by high temperature grease. 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.

Kiln Discharge Seal

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.

Nose Ring Fan

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.
