2. Grate coolers
2.1 Technology
Cooling takes place on the principle of a cross-current exchanger, so the grate cooler consists of two enclosures separated horizontally by one or more grate planes.
The cooler body above the grid plates is fully protected by a refractory lining. External fans supply cooling air to the casings below the grilles, where it is distributed and blown through the grate plates.

Cooler sizing is a function of the furnace's current or planned future production capacity. Over the past ten years, the specific load (kiln production divided by cooler surface area) has risen from 35 to 60 t/d · m 2 . This development, linked to the increase in the admissible clinker...
