The calcium carbonate powder produced by the grinding mill is an important force in the paper indust2023-06-09 08:28:49
Calcium carbonate is an inorganic compound with the formula CaCO₃, which is the main component of limestone, marble, etc. Calcium carbonate is usually white crystal, odorless, basically insoluble in water, and easy to react with acid to release carbon dioxide. It is one of the common substances on the earth, present in aragonite, calcite, chalk, limestone, marble, travertine and other rocks, and is also the main component of some animal bones or shells. Calcium carbonate is also an important building material and is widely used in industry.
The calcium carbonate powder produced by grinding mill improves the papermaking process
Increasing the content of fillers in paper and reducing the consumption of plant fiber resources and production costs have always been the goal pursued by the paper industry. With the development of papermaking technology, the papermaking process has changed from acidic papermaking to neutral and alkaline papermaking, and the amount of calcium carbonate in the papermaking industry has greatly increased, which can be used as a filler and also as a high-quality paint pigment to reduce costs and strengthen products.
Calcium carbonate as paper filler:
Calcium carbonate fillers are tiny, white mineral powders that are generally insoluble in water or slightly soluble in water. The main purposes of adding calcium carbonate to paper are: disperse in the slurry fibers to fill the void, improve the opacity of the paper and other optical properties; Improve the ink absorption of paper, so that paper has better printability; Meet some special performance requirements of paper, such as improving the electrical conductivity and heat resistance of paper; Reduce the use of fiber raw materials, reduce production costs, etc.The light calcium carbonate used as papermaking filler has powder, paste and paste, and the heavy calcium carbonate has powder and paste and so on. Heavy calcium carbonate as filler is mainly used in printing paper, writing paper, office paper and advertising paper. Light calcium carbonate can in principle be used in all paper.
In the context of the world's advocacy of energy conservation, green production and the shortage of paper fiber raw materials, the growth of paper production capacity may be inhibited. Therefore, the huge reserves of resources, low price and environmental protection, stable quality and strong plasticity of calcium carbonate can continue to bring a second life to the paper industry.
For calcium carbonate grinding, our company recommends the use of HGM grinding mill
HGM mill is a mill designed for processing various non-flammable and non-explosive materials with Mohs hardness less than 9.3 and humidity less than 6%.
HGM series mill is widely used in mining, metallurgy, chemical industry, building materials and other industries. They were able to grind the material into a fine powder of 325 to 2,500 mesh. If it is used in papermaking technology, calcium carbonate needs to be processed to 800 ~ 1500 mesh.
HGM mill features:
- High grinding efficiency.
- The HGM mill is equipped with a high pressure spring system to increase grinding force and improve grinding efficiency.
- Multistage grinding: The HGM mill consists of multiple grinding rolls and grinding rings arranged in a stepped structure. This design allows for multiple grinding stages, improving grinding results and achieving finer granularity.
- Energy-saving design :HGM mill is equipped with frequency control system, which can adjust the speed of the main engine and save energy consumption.
- Advanced grading system: The HGM mill is equipped with an efficient grading system to control the size distribution of the final product. This ensures consistent product quality and narrow particle size distribution.
