硅灰石针状粉制备技术的现状与设想

The Present Situation and Conception of Milling Technology for Preparation of Needle-like Wollastonite Powder

具有足够长径比的超细硅灰石针状粉在工业上有着极高的应用价值 ,提高硅灰石产品的长径比 ,关键在于在粉碎过程中保持矿物原有的结晶结构。硅灰石针状粉超细粉碎技术的关键是如何使加工过程更趋符合其粉碎机理的要求 ,但目前还有一定的差距。本文的目的就在于总结现有的硅灰石超细粉碎技术 ,找出存在的问题 ,提出设想 ,以便促进该技术的更大发展。

Needle like wollostonite powder with length diameter ratio high enough for industrial application has great use value.The key of increasing its length diameter ratio is to retain the primary crystal structure during the milling process.The crux of milling technology for preparation of needle like wollastonite powder is how to make the process accord with the milling mechanism.But at present,the technology still has a certain way to go.In this paper,we reviewed the existing milling technologies of wollastonite ultrafine powder,found out their main problems,and put forward some conception
