目前，硅灰石针状粉制备工艺研究的主要着眼点，仅在于提高长径比．而某些应用领域要求硅灰石针状粉不仅具有较高的长径比．而且具有较高的细度。这种任度很小的外状粉称为短纤维针状粉。作者采用振动后对此类产品的制各工艺进行了探讨。
At present, the main focus of research on the preparation of wollastonite acicular powder is only to improve the aspect ratio. In some fields of application, wollastonite needles not only have a higher aspect ratio. And with high fineness. This is a very minor degree of powder called staple fiber acicular powder. After using the vibration of the system of these products were discussed.
