Wollastonite powder is white micro-belt gray, red, in the form of flakes, radial or fibrous aggregates, with glass luster, cleavage mask pearl luster. Pure wollastonite is rare in nature. After grinding by raymond mill, the wollastonite powder can be used in plastics, rubber, paint, papermaking etc, and it has an important position in modern industry.
Application of wollastonite powder
Wollastonite deep processing products are widely used in plastics. As a plastic filler, it is mainly used to increase tensile strength and flexural strength and reduce costs.
Natural wollastonite powder has a special needle-like structure, white, non-toxic, after ultra-fine pulverization, surface modification is an ideal filler for rubber, not only can reduce the production cost of rubber products, but also improve the mechanical properties of rubber, give rubber special features that itself doesn’t have.
Wollastonite powder is used as a filler for paints and coatings to improve the physical and chemical properties of the product, to maintain durability, to reduce the gloss of the paint, to enhance the expansion ability of the paint, to reduce cracks, and to reduce the oil absorption and enhance the corrosion resistance.
The wollastonite powder can be used as a filler and plant fiber to form a papermaking composite fiber to replace part of the plant fiber. Reduce the amount of wood pulp, reduce the cost, improve the paper product performance, improve the smoothness of the paper, opacity, improve the uniformity of the paper, eliminate the static electricity of the paper, reduce the shrinkage of the paper, good printability, and reduce the plant pollution emissions during fiber pulping.
For raymond mill, we recommend Guilin Hengda HD series raymond mill to you, it has the following advantages:
1.High capacity and low consumption, the output is increased by 20%-30% compared with traditional Raymond machine, impeller type fan is used, which efficiency is higher than straight blade type fan, once oil can be used for 30-45 days;
2.Powder classification accuracy is higher, without coarseness missing, the accuracy is 80-600 mesh, classification efficiency of 99%;
3.Efficient and stable, grinding roller and grinding ring always contact during operation; environmental protection, low vibration, low noise.
