CPG supply cooler in two independent entities which are joined together for maximum recuperation of Heat.
A) Inlet Stationary Inclined Grate (ISIG):
This is an inclined arrangement of specially designed anti spillage Grate plates, arranged in downward steps formation. These Grate Rows do not move. The Castable cover is shaped in such a way to have spread of hot clinker on grate without void.
The high depth hot clinker bed is formed which is supplied with a concentrated Air load underneath. This results in quick and high grade heat recovery from clinker. This heat is supplied in the form of Secondary and Tertiary Air flow to kiln and Calciner at optimum proportions.
B) Reciprocating Grate Cooler:
As ISIG does the major heat recovery task, for balance Clinker cooling it is equipped with conventional Reciprocating Grate Cooler.
