雷蒙磨粉机在铜镍铂（族）矿石标准物质制备中的应用

Application of Raymond Mill in Preparation of Reference Materials of Cu-Ni-Pt (Group) Ores

摘要: 介绍了雷蒙磨粉机原理。采用雷蒙磨粉机，对不同含量铜镍铂（族）矿石标准样品加工至粒度小于0．074mm。选择合适的磨球和样品质量比，球磨机磨-混24～72h。样品经粒度筛分试验、均匀度及稳定性检验，证明其中被检验元素分布均匀。

Abstract: In this paper the working principle of Raymond mill was introduced.The Cu-Ni-Pt(group) ore reference materials with grain size of less than 0.074 mm were prepared by Raymond mill.Then the samples were milled and thoroughly mixed for 24~72 h in a boll mill
