QUICK LIME POWDER
[CODE NO 3389]
Quicklime (or calcium oxide (CaO), or burnt lime, or unslaked lime), is obtained by calcining (controlled heating - time and temperature) limestone at temperatures above 900°C. This highly reactive product is essential to many industrial processes
It is also known as caustic lime. It is obtained by calcination (i.e. heating to redness) of comparatively pure lime stone. It is amorphous in nature, highly caustic and possesses great affinity to moisture. Quicklime is also known as burnt lime.
Quicklime (calcium oxide) is a white solid having a crystalline structure. Quicklime is highly reactive with water, generating considerable heat in the hydration process. It can be bought at masonry supply stores.
Quicklime is the compound which is used commonly for whitewashing houses. The chemical name of quick lime or lime is calcium oxide. The chemical formula of quicklime is CaO.

PROCESS FLOW CHART
MANUFACTURING PROCESS OF QUICK LIME
QUICK LIME PROCESSES MAINLY CONTAINS THE FOLLOWING BASIC STEPS
1. PROCUREMENT OF RAW MATERIAL (LIME STONE)
2. LIME STONE STORAGE AND PREPARATION
3. CRUSHING PROCESS OF RAW MATERIAL
4. SCREENING PROCESS
5. WASHING PROCESS
6. STORAGE OF LIME STONE
7. FUEL STORAGE AND PREPARATION
8. CALCINATION PROCESS
HEAT TRANSFER IN LIME BURNING CAN BE DIVIDED INTO THREE STAGES:
(A) SHAFT KILNS
CHARGING OF RAW MATERIAL
DRAWING OF LIME
STILL MORE SOPHISTICATED DRAWING MECHANISMS ARE USED, SUCH AS;
