Quick Lime Plant Process
- Raw Material Pre-processing
A quick lime production plant uses high-quality limestone as raw material, high-quality limestone has higher CaO content and lower impurity content. Using a stacker reclaimer machine to stack the limestone uniformly. Then, the limestone is fed into a limestone crusher ( jaw stone crusher, hammer stone crusher, cone stone crusher, impact crusher). The large-size limestone is crushed dimensions suitable for calcination, generally under 50mm, which facilitates the next step of calcination. Through circular vibrating screen or linear vibrating screen to Sieving limestone of different grain sizes, ensure calcination uniformity.
- Calcination
Calcination is the most important step in a quick lime production plant, it is the key aspect to ensuring the productivity and quality of quick lime. The fuels that are calcined at the quick lime production plant are natural gas, coke gas, coal, carbide furnace gas, etc. Limestone entering the kiln, preheating of limestone using high-temperature exhaust gases from kiln discharge. Starts to decompose when it enters the high-temperature zone, the temperature up to 1100°C. Commonly used kilns are annular lime kilns, twin shaft lime kilns, double beam lime kilns, and limestone rotary kilns. After calcination, quick lime will be rapidly cooled down by a cooling system. Exhaust gases from calcination will be cleaned by an exhaust gas treatment device. Conforms to the requirements of environmentally friendly production.
- Finished Product Handling
Calcined quicklime needs to be further processed at the quicklime production plant. Quicklime needs to be stored in sealed or dry warehouses, which prevents exposure to water. Quicklime has different particle sizes, using a circular vibrating screen or linear vibrating screen to sieve out quicklime of different particle sizes. The quicklime will be packaged and transported according to different particle sizes. Customers or industries have particular requirements for forms of quicklime, we can grind quicklime to the right fineness using a limestone grinding mill.

Difference Between Quick Lime Plant and Hydrated Lime Manufacturers Plant
- Process: The raw material of the quick lime plant is limestone, limestone (calcium carbonate) calcined at high temperatures, the reaction releases carbon dioxide to form calcium oxide, also known as quicklime. The raw material of the hydrated lime manufacturers plant is quicklime, a chemical reaction of quicklime with water that generates hydrated lime.
- Equipment: The main equipment of the quick lime plant are lime calcination kiln, limestone crusher, dust handling equipment, etc. The hydrated lime manufacturer plant adds to these with digesters, water treatment plants, dewatering units, and more.
- Physical Property: Quicklime is hygroscopic and corrosive, and reacts with water to give off a lot of heat. Hydrated lime is more stable than quicklime, slightly soluble in water and alkaline.
What is Quicklime Used For
—— AGICO’s quick lime plant can be used in many industries.
Building Industry
- Quicklime is an important raw material to make concrete, mortar, and other building materials. The addition of lime gives these materials better bonding properties. Quicklime also can regulate the fluidity and hardening time of concrete and mortar, raising the durability and stability of the building. It is widely used in masonry, plastering, building walls, road construction and other projects.
Chemical Industry
- Quicklime is an important raw material to make calcium hydroxide, calcium chloride and other chemicals. These chemicals can as bleaching agent, flocculant, desiccant in papermaking, dyeing and pharmaceuticals.
Environmental Industry
- Environmental protection is the basic requirement for factories. Quicklime can be used for wastewater treatment and flue gas desulphurization. Through chemical reaction to adjusting the PH of the water and reducing the acidity of wastewater. Quicklime reacts with sulfur dioxide in the flue gas to produce solids such as calcium sulfate, Effectively removing the sulfur oxides in the flue gas.
