Complete Plant Scope
Process Limestone into Quicklime and Hydrated Lime Products
A lime production line transforms limestone through controlled calcination. The plant can be configured for quicklime lump, quicklime powder or hydrated lime production according to the intended industry, capacity, fuel availability and finished-product requirements.
Quicklime
Calcined limestone is cooled, screened, stored or further processed into quicklime powder.
Hydrated Lime
Quicklime can be hydrated, aged and classified to produce hydrated lime for application-specific use.
Calcination Principle
From Calcium Carbonate to Calcium Oxide
During calcination, limestone is heated under controlled conditions in the kiln. Carbon dioxide is released and the limestone is converted into quicklime, which can then be cooled, stored, ground or hydrated according to the final-product route.

FAQ
Lime Production Line Questions
What is a lime production line?
A lime production line is an integrated plant that prepares limestone, calcines it into quicklime, cools and stores the product, and can include downstream quicklime powder or hydrated lime processing sections.
What is the difference between limestone and quicklime?
Limestone is primarily calcium carbonate. Quicklime is calcium oxide produced when limestone is calcined under controlled conditions in a lime kiln.
What equipment is needed for quicklime production?
A typical quicklime plant can include crushing and screening equipment, a lime kiln system, preheating and cooling equipment, conveyors, storage systems, dust collection and product dispatch equipment.
Can a lime production line produce quicklime powder?
Yes. After calcination and cooling, quicklime can be transferred through enclosed handling equipment to a grinding, collection, storage and packing system for quicklime powder production.
How is hydrated lime produced from quicklime?
Hydrated lime is produced by reacting quicklime with a controlled amount of water, followed by aging, classification and finished-product handling as required by the application.
Why are crushing and screening important before calcination?
Controlled limestone size helps support stable kiln feeding and more consistent thermal processing. The required stone fraction depends on the selected kiln system and production target.
What fuel can be used for a lime kiln?
Fuel selection depends on local availability, project conditions, kiln configuration and operating requirements. Fuel supply and combustion control should be evaluated during plant planning.
What information is needed to design a lime production plant?
Please provide limestone composition, stone size range, moisture content, target product, required capacity, available fuel, project location, site conditions and any applicable dust-control or gas-treatment requirements.
