What is Slaked Lime and How is it Produced? A Deep Dive into its Features, Uses, and Manufacturing Process

As a professional mining and powder equipment manufacturer with extensive industry experience, Cronus provides a comprehensive series of high-performance mechanical equipment specifically designed for hydrated lime production. Our complete production line solutions cover every stage from raw material processing to final product packaging, ensuring efficient, stable, and environmentally friendly hydrated lime manufacturing.

What is Slaked Lime？

Slaked Lime, chemically known as calcium hydroxide (Ca (OH)₂), is a white powder and an inorganic compound with strong alkaline properties. Quicklime is widely used in many fields such as construction, agriculture, chemical industry and environmental protection.

For example, it is often used as a building coating in the construction industry; it can be used as a soil conditioner in the agricultural field; it can also be used as a sewage treatment agent in chemical production and environmental protection operations.

Preparation of Slaked Lime

The limestone, whose main component is calcium carbonate (CaCO₃), is placed in a high temperature environment of 900-1200℃ for calcination. During this process, the limestone will decompose to produce calcium oxide (CaO) and carbon dioxide (CO₂).

Hydration reaction (digestion)

The prepared quicklime is mixed with water, and an exothermic reaction will occur at this time, and calcium hydroxide, that is, slaked lime, will eventually be produced. In this link, it is usually necessary to accurately control the amount of water and temperature to ensure that the reaction can proceed fully, thereby producing high-quality slaked lime products.

Hydrated lime processing equipment from Cronus

Mainly used for fine grinding of slaked lime. The equipment can grind materials to 80 – 400 mesh, and even higher fineness standards.
It is particularly suitable for small and medium-sized slaked lime production, with the significant advantages of compact structure and convenient operation.

Vertical grinding mill

This equipment is designed for large-scale industrial slaked lime production and has the outstanding characteristics of high output and low energy consumption.
It can not only handle materials with high humidity, but also is equipped with an intelligent control system, which greatly improves production efficiency.

This is a device specially designed for the slaked lime digestion process. By automatically controlling the water-ash ratio, the reaction efficiency is effectively improved, while the undigested particles can be reduced, effectively ensuring the stability of product quality.

The main function is to finely grade the ground slaked lime, which can fully meet the diverse needs of different industries for powder fineness.

As a vital industrial raw material, calcination and hydration play a decisive role in the production process of slaked lime. The series of equipment provided by Cronus, such as grinding mills, digestion mills, powder selectors, etc., can help customers efficiently produce high-quality slaked lime powder, fully meet the actual needs of multiple industries such as construction, environmental protection, and chemical industry, and provide solid and strong support for the development of related industries.
