Twin Shaft Regenerative (TSR) Kilns | MEKITCO
The Twin Shaft Regenerative (TSR) kiln is a double-shaft vertical kiln which utilizes the regenerative process for lime calcination. When one shaft operates in burning mode, the other shaft operates in regeneration (preheating) mode. Each shaft operates for an equal period of time in burning and regeneration modes.

Vertical Shaft Kilns
Vertical Shaft Kilns. Lime shaft kilns are stationary vertical kilns where the raw limestone enters at the top and gravity flows through three thermally zoned sections known as the preheating, calcining, and cooling zones. The process heats the limestone from ambient temperature to 900°C, which is the point where the carbon dioxide is driven ...
