Calcined Lime And Its Uses

Calcined Lime is prepared by the calcination of limestone. Limestone is a naturally occurring, abundant sedimentary rock that consists of high amount of calcium or magnesium carbonate along with other minerals. It also contains a considerable amount of silica in the forms of lint, clay, silt and sand. It is a commonly used mineral. One of the most popular uses of Limestone can be traced in architectures. You can find the use of this material in lots of landmarks around the globe, particularly North America and Europe.

The term "lime" refers to a combination of three related substances - limestone, burnt lime and hydrated lime. They are used for different purposes, from preparation of fertilizer to manufacturing of glass and cement. Burnt and hydrated limes are generally used in:

• Steel industry (as a flux)
• Pulp and paper industry
• Gold mining
• Road stabilization
• Water treatment
• Wastewater treatment

The Production Of Calcined Lime

Below-mentioned are the typical processes involved in the production of Calcined Lime:

Quarrying: First of all, Limestone is obtained by blasting short holes in a quarry face. Generally, a small vertical drill is created around twenty feet deep from the terrace. Also, a plug of gelignite is exploded at the bottom to form a chamber so that more explosives can be used to create a bigger blast.

Sizing: The succeeding stage to quarrying is sizing. Limestone is thrown into primary crusher that breaks the rock into smaller pieces. Depending on the requirement of the final product, the stone may be sent to secondary or tertiary crusher to further reduce it in size. The stone is then sorted into various sizes ranging from grit to fine particle. The sized stone is subsequently sent for washing.

Calcination: Once washed, the processed stone is transported by conveyer belts to lime furnace. The process of calcination can be divided into three main stages:

• Preheating - In preheating, limestone is heated in a furnace at an extremely high temperature.
• Calcination - During calcination, the furnace fuel is burned in the preheated air from the cooling zone, and as the limestone moves down the furnace, the heat turns the mixture into quicklime and carbon dioxide.
• Cooling - In the cooling stage, quicklime is cooled through direct contact of cooling air.

Why Calcined Lime Is Extensively Used?

Calcined Lime has excellent properties and is extremely cheap and very effective. And because of the very same reasons, the material is widely used for the construction of roadbeds, building, and cement. In addition to this, Calcined Lime is an ideal choice for flooring and building blocks due to its subtle pattern and neutral colors.
