Wollastonite crushing process and processing equipment

Wollastonite is a calcium metasilicate mineral salts, is one of the emerging industrial raw materials much attention, it has a special needle-like structure, white, low oil absorption, in addition to other mineral powder should have the same fine granulation and surface activation, to be as much as possible to maintain its aspect ratio. Therefore, to obtain high aspect ratio wollastonite ultrafine powder, is a prerequisite for wollastonite deep processing and utilization. Wollastonite products can be divided into high aspect ratio wollastonite wollastonite and ground into two categories, including more extensive use of high aspect ratio wollastonite, thus enhancing the high aspect ratio wollastonite, surface modification of silica fume Stone and function name wollastonite mineral materials of high value-added products for preparing new technologies, new processes, new research on the theory and application of wollastonite industrial restructuring, industrial upgrading has great significance, and will have significant social, economic and environmental benefits. How to choose the right way and smash the production process conditions to produce high aspect ratio (> 15) of wollastonite products, improving quality and market competitiveness of products wollastonite, wollastonite maintain the sustainable development of enterprises, increase business The economic benefits, is an area of ​​concern in the preparation of wollastonite problem.

Wollastonite crushing equipment progressively broken equipment: crushing equipment jaw crusher, broken equipment can also be used crusher crushing jaw crusher and cone crusher, cone crusher generally used in large ore hardness, After using crushing machine, the three sections of a closed process the raw material crushed to -2.5MM, then finely ground. Using a ball mill grinding equipment, vibration mill, mixing mill and vertical mill. After testing, ball mill, vibration mill, mixing mill is not well protected topography wollastonite needle-like crystals, and the products are to varying degrees over crushed phenomenon, Vertical Mill wollastonite mineral crystal shape can be obtained looks good needle wollastonite products. Wollastonite smash smash product with different morphologies of different devices which take advantage of the excellent characteristics inherent wollastonite obtain high aspect ratio wollastonite ultrafine powder to improve its value is to carry out deep processing of wollastonite with the premise utilization.
