The use of phosphogypsum to prepare phosphorus building gypsum (PBG) is of great value to the resource utilization of phosphogypsum. In this study, PBG was ballmilled to obtain phosphorus building gypsum with good performance, which can meet the requirements of the Chinese standards for firstclass building gypsum. Meanwhile, the changes of net slurry physical properties, mechanical ...

Initially, 3 g red phosphorus (RP) powder and 23 stainless steel balls with diameter of 10 mm were sealed in the 50 mL steel vessel in glove box filled with argon, and the steel vessel was then fixed in the highenergy ballmilling machine (Retsch, Emax). The conversion from RP to BP was realized by ball milling at 1500 rpm for 5 h.

The invention relates to a process for making red phosphorus by subjecting molten yellow phosphorus to a thermal conversion reaction in a closed reaction zone. To this end, a hollow shaftprovided and closed ball mill is preheated to a reaction temperature within the range 280° to 590° C. Yellow phosphorus is continuously introduced into the ball mill through the hollow shaft in quantities ...

Grinding. Dry grinding tests on high purity hematite were carried out in a planetary ball mill (Pulverisette6, Fritsch) with one steel pot of 50 cm 3 inner volume, under atmospheric conditions (Sanshez et al., 2007, Pourghahramani and Forssberg, 2007a, Pourghahramani and Forssberg, 2007b).Steel grinding media (ρ = g/cm 3) with ball to powder ratio of 3:1 was used in this milling ...

The ratio of ball to powder, the time of milling and the rotation rate are the main determinant factors of milling energy. We first investigated the different ratio of ball to powder (100:1, 200:1, 50:1) under a rotation rate of 500 rpm, and the samples were marked as XBP20h100:1, XBP50h200:1, XBP10h500:1.

In Conclusion. While they both involve the physical removal of material from a workpiece, milling and grinding aren't the same. The former machining process is characterized by the use of a milling machine, whereas the latter machining process is characterized by the use of a grinding wheel. No tags for this post.
