The lime is air-hardening inorganic bond materials, whose main component is calcium oxide. It is obtained by calcinating high content of limestone, dolomite, chalk, shells, etc., by 900 ~ 1100 ℃. And it is the earliest bond material of human applications. And it is widely applied in civil engineering, also be used in medical usages domestically. Thus, quite a lot of poetries about the lime from the ancient spread until today.
Depending on the industrial use of lime powder, lime milling process generally as follows.
1. Limestone, dolomite, chalk, shells and other materials with high calcium carbonate content 900-1100 ℃ after calcination to obtain lime.
2. If the size is bigger than the feeding size of the lime obtained by calcining lim,,we might need a small jaw crusher or hammer crusher.
3. After the broken material into the lime mill production systems, Milling, grading and other operations are completed within the mill automation.
4. Qualified sub-lime powder will be released by the discharge valve and packaging products.
By Shanghai Shibang Machinery Co., lime powder grinding equipment specially developed grinding grade, the production of lime powder with high purity and high brightness, ultrafine particle size, and according to the needs of different customer fineness in 80 mesh to 3000 inter head adjustment, widely used in many fields of chemical, plastics, pharmaceuticals, rubber, coatings, architectural concrete aggregate and road construction, has been recognized by domestic and foreign customers.
The milling machine used in grinding and processing of metallurgy, building plastics, fillers, cosmetics, chemicals and other industries……
Widely used in electric power, mine, metallurgy, chemical engineering, steels, building materials, coal industries, producing huge economic and social benefits.
With the development of modern science and technology, more and more industrial use of lime was found that the market demand is expanding year by years, more and more investors began to enter the lime processing industry.
The main use of Lime
Lime powder is widely used in papermaking, plastics, plastic film, chemical fiber, rubber, adhesives, sealants, household chemicals, cosmetics, building materials, coatings, paints, inks, putty, sealing wax, putty, carpet packaging, pharmaceuticals, food (such as chewing gum, chocolate), feed, and its role are: increased product volume, reduce costs, improve the processing performance (e.g., to adjust the viscosity, rheological properties, curing properties), improved dimensional stability, a reinforcing or semi-reinforcing, improve printing performance, improve the physical properties (such as heat resistance, matting, abrasion resistance, flame resistance, whiteness, gloss) and the like.
