Embodiment Construction
[0063] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.
[0064] see figure 1 A kind of superfine acicular wollastonite powder production process of the present invention, comprises the following steps,
[0065]Crushing wollastonite raw ore until the average particle size is less than 1cm, crushing with a pulverizer to obtain needle-shaped powder with a sedimentation value of 60-90, vibrating and sieving the needle-shaped powder to obtain needle-shaped powder with a high aspect ratio, and then Enter the jet mill for jet crushing to obtain acicular wollastonite powder with a fineness of 600-3000 mesh and an aspect ratio greater than 10:1.
[0066] Specifically, it also includes the step of primary crushing the wollastonite raw ore to an average particle size of less than 5 cm, and then sending it...
