Wollastonite Vertical Mill | Direct From Manufacturer

The price of titanium dioxide has soared, and finding alternatives to titanium dioxide has become an urgent problem to be solved. Industry insiders have turned their attention to wollastonite. What is the reason for the continuous rise in the price of titanium dioxide? Why does wollastonite become the preferred substitute for titanium dioxide? What are the wollastonite grinding mill equipment for titanium dioxide substitute?

Reasons for the price rise of titanium dioxide

The urgent need to find alternatives to titanium dioxide is due to the rise in the price of titanium dioxide for several reasons:

　　（1）With the increase of raw material cost of titanium dioxide, the state vigorously promotes the progress of green mines and environmental protection projects, and many titanium mines are overhauled, resulting in insufficient supply.

　　（2）The production process of titanium dioxide is more difficult. The state restricts the sulfuric acid process of titanium dioxide, resulting in that titanium dioxide can only be produced by chlorination, but now most manufacturers have not broken through the technical barrier of producing titanium dioxide by chlorination;

　　（3）Under the new situation of the epidemic situation, the demand for the application of titanium dioxide in the field of sterilization has increased greatly. It was originally widely used in architectural decoration coatings, plastics, papermaking and other industries. The new market environment has opened a new market for titanium dioxide, resulting in a shortage of titanium dioxide resources and rising prices.

Alternative products of titanium dioxide are more recognized in the industry

In order to alleviate the great pressure on enterprises caused by the continuous rise in the price of titanium dioxide, people in the industry are constantly looking for alternative products of titanium dioxide. At present, several relatively recognized products are wet calcium carbonate, anhydrous calcium sulfate, kaolin, nano barium sulfate, wollastonite and other alternative titanium dioxide. It is widely concerned in the industry to use wollastonite powder as a substitute for titanium dioxide. Because wollastonite powder has special needle structure, high whiteness and refractive index, and its hiding power is higher than that of most white minerals.

However, wollastonite grinding powder has always used dry processes such as Raymond mill machine, impact mill or air mill. Although the fiber structure of the product can be retained, there are process level restrictions in the realization of ultra-fine wollastonite. Wollastonite as a substitute for titanium dioxide has not been realized on a large scale.

HCH ultra-fine mill and HLMX super-fine vertical mill produced by HCM

HCMilling (Guilin Hongcheng) has been deeply engaged in the grinding industry for many years. After years of research and development, it has broken through the bottleneck of ultra-fine powder processing capacity and developed an ultra-fine vertical grinding machine that can replace imported equipment and carry out large-scale production. It is especially suitable for ultra-fine grinding mill equipment for deep processing of wollastonite, The product fineness can be adjusted between 325 mesh and 2500 mesh as required. The product fineness can reach D97 ≤ 5 at one time μ Mdehch series superfine ring roller mill plays an important role in wollastonite replacing titanium dioxide.
