Lime is an air-hardening inorganic cementitious material with calcium oxide as its main component. Lime is made of limestone, dolomite, chalk, shells and other raw materials with high calcium carbonate content, which are calcined at 900-1100 °C. Lime is a cementitious material used earlier by humans. Lime is widely used in civil engineering and can also be used for medical purposes in my country.

Lime processing and production process

Depending on the industrial use of lime powder, the grinding process of lime is generally as follows:

The first stage

Limestone, dolomite, chalk, shells and other raw materials with high calcium carbonate content are calcined at 900-1100 ℃ to obtain lime.

The second stage

If the lime size obtained after calcination is higher than the input size of the lime mill, it will be crushed by a small jaw crusher or hammer crushing.

The third phase

After crushing, the material enters the lime mill production system, and operations such as grinding and grading are automatically completed in the mill.

The fourth stage

Qualified lime powder is released by the discharge valve, and the finished product is packaged.

Required equipment

After being crushed and classified by the lime powder grinding equipment independently developed by CLIRIK, the lime powder produced has high purity, high whiteness and ultra-fine particle size. And it can be adjusted between 80 meshes and 3000 meshes according to the different fineness requirements of customers. It is widely used in many fields such as chemical industry, plastics, medicine, rubber, paint, construction concrete aggregate and road construction. It has been unanimously recognized by domestic and foreign customers.

Main uses of lime

Lime powder is widely used in papermaking, plastics, plastic films, chemical fibers, rubber, adhesives, sealants, daily chemicals, cosmetics, building materials, coatings, paints, inks, putties, sealing wax, putty, felt packaging, medicine, food (eg chewing gum, chocolate), in feed. Its functions are: increasing product volume, reducing cost, improving processing properties (such as adjusting viscosity, rheological properties, vulcanization properties), improving dimensional stability, reinforcing or semi-reinforcing, improving printing properties, and improving physical properties (such as heat resistance). properties, matting, abrasion resistance, flame retardancy, whiteness, gloss), etc.
