How Can The Calcium Silicon Slag Grinding Mill Be Used In Papermaking Industry?

The global rise in pulp, logistics, energy and other prices in the upstream of paper industry directly increases the production cost of enterprises. Due to the rise in the price of pulp raw materials, the price of pulp and paper is inverted, resulting in the shutdown of some paper mills. Many manufacturers are looking for fillers. Calcium silicon slag grinding mill can benefit for paper-making industry.

At present, the gap of fiber raw material increases year by year, the raw material structure is unreasonable, and the proportion of wood pulp is low. In recent years, the special properties of paper are increasing. The proportion of non fiber raw materials as fillers is increasing. At present, the filler has become the second largest raw material of paper making, and calcium silicon slag paper making may become a new filler.

What is calcium silicon slag?

In the face of the lack of raw materials for paper manufacturing, many enterprises began to try to use different materials instead, calcium silicon slag papermaking has become an indispensable alternative product.

Hydrated garnet, commonly known as calcium silicate slag (hydrated calcium aluminosilicate), is the main slag phase after deep desilication of alumina with lime in sintering process. Its chemical formula is 3CaO. Al2O3. Xsio2 · (6-2x) H2O. Wollastonite in calcium silicate slag has high whiteness, good thermal and chemical stability. The addition of calcium silicon slag in papermaking can not only play the role of traditional papermaking filler. It can also save plant fiber materials and improve the opacity, covering power and other optical properties of the paper to a certain extent.

The calcium silicon slag and plant fibers are interweaved into "plant fiber calcium silicon slag network" when some of them replace plant fibers. It can also improve the physical strength index of paper within the allowable range. It is necessary to treat calcium silicon slag in papermaking to save pulp raw materials and promote the application of calcium silicon slag in papermaking.

Vertical roller mill machine for calcium silicon slag produced by HCM

HLM series vertical mill adopts standard module to design and manufacture pressure device. With the increase of mill capacity, the number of grinding rolls should be increased accordingly (2, 3 or 4 grinding rolls can be used, and 6 grinding rolls can be used at most). With a small number of standard module components, a variety of capacity series products are formed to meet the requirements of different materials processing different product fineness and output.
