Wollastonite Vertical Mill | Sale Wollastonite Grinding Mill Equipment

As the world's largest producer and consumer of paper products, China has limited the source of paper raw materials due to the "waste prohibition order", coupled with the lack of wood in China, the insufficient production capacity of domestic raw pulp and the high cost of imported raw pulp. Therefore, many paper enterprises try to replace paper with some mine materials to solve the bottleneck in the paper-making process. Wollastonite can solve a large part of the problems in the paper industry.

Advantages of wollastonite in papermaking industry

Wollastonite is a naturally produced chain calcium metasilicate mineral. Pure wollastonite is bright white and gray grayish brown when mixed with other impurities. Naturally occurring wollastonite is usually needle shaped, radial, fibrous or plate-shaped. Mohs hardness is 4.5 ~ 5.5, density is 2.75 ~ 3.10g/cm3, melting point is 1540℃. Wollastonite is ground into ultra-fine powder, which is called "mineral fiber". 1250 mesh wollastonite is used in papermaking as a filling agent for papermaking. It can replace 25% ~ 35% wood pulp, and the modified wollastonite can significantly reduce pulp consumption. To a great extent, it can save the amount of plant fiber, indirectly reduce the cutting and utilization of forest resources, reduce production costs and maintain ecological balance.

Application and development trend of wollastonite in Papermaking

Wollastonite is rich in savings in China, and the price is relatively cheap. At present, wollastonite is used to replace plant pulp in papermaking. The raw pulp with ultra-fine wollastonite powder has high whiteness and good chemical and thermal stability. And in practical application, it can give play to the characteristics of high flame retardancy, high resistance and low dielectric constant, so as to improve its heat and corrosion resistance.

Grinding wollastonite into ultrafine powder instead of plant pulp to realize ore papermaking. In Yunnan, thousands of tons of high-quality paper have been produced. At present, after this major technological innovation is extended to Shaanxi, Sichuan, Shandong and other places, more paper mills can replace some wood with ore in papermaking.

Wollastonite has a broad application prospect in the development of paper industry, and it is the main trend of the development of the industry in the future. At the same time, China's wollastonite reserves are very rich and the price is relatively low, but its overall application level is not high. It is still necessary to further strengthen scientific research and explore its application technology and methods. In addition, the application of wollastonite in the paper industry has special properties that can not be replaced by traditional fillers, such as needle structure, which is conducive to the interweaving of fibers and the formation of high physical strength. When fibrous wollastonite is used, the paper has high whiteness and superior chemical and thermal stability. In the process of practical application, it can give full play to its characteristics of high flame retardancy, high resistance and low dielectric constant, so as to improve its heat and corrosion resistance.

In addition, wollastonite has good adsorption, which is conducive to reducing suspended solids in water and effectively reducing the cost of white water treatment. The application shows a good development trend in the paper industry and fully improves the production quality of the paper industry.

Wollastonite is used in papermaking

Wollastonite used in papermaking needs to be ground into ultrafine powder below 1250 mesh to improve the activity of wollastonite.
