Rotary Kiln Plant

The Rotary Kiln is used for calcinations of different type of materials at required Temperature.

 SHELL : Made of thick B.Q. Plate as per IS 2002 Gr. B  or of equivalent quality, 16 mm thick plain section, 32mm tyre section and 48 mm Gear section, electrically welded, Cylindrical type, 2 sets of Tyres are fixed at both ends of the shell which rotates on 4 Nos. Rollers, fixed with the shaft, Phosphorus Bronze Bearings in water cooled Bearing Blocks. The shell of the Kiln is rolled to maximum tolerance with high precision & is sufficiently Strong to accept reasonable overloads and thermal Stresses. Tyre and Gear section of the shell (where tyre and gear will be fitted) are properly machined. At the feeding end of the Shell, a M.S. Conical shell made of B.Q. Plate is fixed for easy Flow of Flue. The Kiln of the Shell is mounted on 2 Nos. of M.S. Base Frame with 4 Nos. supporting Rollers, Bearings and Bearing Housings supporting 3 Nos of steel Tyres & Thrust Rollers. A spicily designed S S Nose Ring is fitted as the discharge end of the shell  

 RIDING RING : There are 2 Nos. riding rings (Tyres) fitted on the Kiln Shell. It is designed for full floating and are machined all over the surfaces. The inside diameter of the riding ring & outside diameter of the riding ring pads are designed to have sufficient clearance so that when the kiln becomes hot, the riding rings will snug fit and adjust the expansion of the material. The riding rings are made of Alloy Steel Castings as per IS-1030, Gr. I.                                    

SUPPORTING ROLLER : Made of Alloy Steel, as per IS-1030, Gr. I. properly machined. Alloy steel shaft (Forged EN- 8) is fitted with the Roller. Each roller is fitted with 2 Nos. water cooled C.I. Blocks which are fitted with the Phosphorus Bronze Bush. The bush of the Bearings are well lubricated by self Oil Lubricating system in the Bush housing. 

 GIRTH GEAR & PINION : Made of Alloy Steel as per IS – 2644, Gr.1 properly Machined. The teeth of the Gear are  proper hardened. The Gear is fitted on the outside diameter of the kiln shell.                                         

 THRUSTER : It is fixed and remains in contact with the face of the tyre, to prevent the kiln from moving uphill or downhill. The Thruster consists of 1 No. Conical Section Alloy Steel roller which is fixed with a vertical Alloy Steel Shaft. The thruster is kept with all the three riding rings & there are adjusting arrangement systems on the base frame of the thruster                                                        

 BEARING HOUSING : Made of Cast Iron as per Gr. 20. It is fitted with supporting Roller, Roller Shaft and Bearing. The Water Cooling system has been provided for Cooling the Bearing. Continuous Oil Lubrication system has also been provided inside the Block.

 DRIVING : A Girth gear is fitted on the shell and the Pinion is fitted with the “Radicon” (GREAVES) make three stage Helical Gear Box. The Driving shaft rotates through Chain, Sprocket and Power is transmitted by the Motor. The Motor is fitted with Gear Box through a Heavy Duty Resilient Spring Grid Coupling on the Rotary Kiln.
