Quicklime
• Introduction
Quicklime (or calcium oxide, or burnt lime) is obtained by calcining pure limestone at temperatures above 900°C. This highly reactive product is essential to many industrial processes.
"Quick Lime " Limestone Calcination:
CaO
Available products:
Pebble, Ground, Milled, Fluidised lime, Low-dust lime, etc.
