Wollastonite is a rare mineral resource with high whiteness, brightness, hardness and high heat resistance. It can be seen from the processing technology of wollastonite that different equipment will be used in the process from raw ore to grinding and crushing. The ore washing equipment generally adopts screening machinery, and the grinding powder is crushed, We use the LUM ultra-fine vertical mill here. Because its finished material contains less iron, it is used to grind white or transparent materials, The whiteness and clarity of the product are relatively high.
The whole process of wollastonite can be summarized as follows: strictly selecting raw ore - Cleaning - grinding and crushing - Air Separation - Testing Center - qualified delivery. The application of fine wollastonite in plastics includes raw materials with different particle sizes from 600 mesh to 3000 mesh, especially materials with more than 1250 mesh, which can greatly improve the cost performance of stone powder. Activated wollastonite powder is widely used, It is mainly used in inorganic reinforced fillers of polymer matrix composites such as rubber, plastics, PVC soft and hard pipes, and other plastic products. When filled into polypropylene, compared with unmodified wollastonite fillers, under the same filling amount, the tensile strength and bending strength are significantly improved.
According to the ultra-fine grinding principle of the vertical mill, the eye film curve of the specially designed grinding roll sleeve and liner is easier to form a material layer than the ordinary vertical mill when used for ultra-fine wollastonite grinding, so that the mill can grind to the required fineness at one time, but also effectively improve its processing performance and reduce the production cost of the whole wollastonite material.
