PYRO PROCESS
• Pyro processing:
The raw material is heated to exceeding 1,450 °C (2,700 degrees F) in huge cylindrical steel rotary kilns lined with special firebrick. Kilns are frequently as much as 3.7 M (12 pi) in diameter, large enough to accommodate an automobile and longer in manyinstances than the height of a 40-story building. Kilns are mounted with the axis inclined slightly from the horizontal. The finely ground raw material or the slurry is fed into the higher end. At the lower end is a roaring blast of flame, produced by precisely controlled burning of powdered coal, oil or gas under forced draft.
• Burning and cooling:
As the material moves through thekiln, certain elements are driven off in the form of gases. The remaining elements unite to form a new substance with new physical and chemical characteristics. The new substance, called clinker, is formed in pieces about the size of marbles.
Clinker is discharged red-hot from the lower end of the kiln and generally is brought down to handling temperature in various types of coolers. Theheated air from the coolers is returned to the kilns, a process that saves fuel and increases burning efficiency.

|Ashoka offers Rotary kiln Cement plants that speak innovation, quality conscious and cost effective technology. We offer Medium size to Large|
|Size ROTARY KILN Cement plants from 300 TPD to 2000 TPD on turn key basis and have capabilities to undertake allaspects of project |
|including, feasibility studies, technical advice, equipment supply, erectioning, supervisory services, commissioning etc. So that the dust |
|does not escape into the environment highly efficient measures for pollution control have been incorporated in every cement plant. Every |
|material transfer points is installed with Reverse pulse jet filters. Electrostatic precipitator (ESP) treats the Fuel gases from kiln for |
|cleaning before discharging into the atmosphere helping to maintain the eco friendly environment. |
