Natural wollastonite products in accordance with the particle size can be divided into five categories of block particles, ordinary powder, fine powder, ultra-fine powder and needle powder, powder preparation method is mainly mechanical crushing. For wollastonite copy processing equipment are gravel mill, air flow mill, tell mechanical impact magic machine and so on. Mechanical crushing can be divided into dry and wet method, wet method of energy saving, protection of fibre aspect ratio; dry method does not agree with agglomeration. Shear-based mechanical crushing can obtain wollastonite ultrafine powder with high aspect ratio Silicon powder for tile,silica fume for ceramics,silica ash til,white silica fume,Semi-encrypted silica fume Chengdu Rongjian Engineering Materials Co.Ltd , https://www.rjsilicafume.com
