  • Ball Mill an overview ScienceDirect Topics

    In general, ball mills can be operated either wet or dry and are capable of producing products in the order of 100 μm. This represents reduction ratios of as great as 100. Very large tonnages can be ground with these ball mills because they are very effective material handling devs. Ball mills are rated by power rather than capacity. Today, the largest ball mill in operation is 8.53 m

    Figure 1. Schematic representation of the crushing mechanism in a ball mill In wet grinding, the surrounding medium is liquid, as opposed to dry grinding. Wet grinding should be considered in cases where the material is prone to static charging, or when the material is toxic and dust containment is difficult. Also wet grinding can be used when

  • Question about ball milling Pyrotechnics APC Forum

    You can 'wet mill' black powder. When I first ball milled my black powder I was told by a scientist that wet milling would be the safest way to do it. I added a little too much water, but once I got it out I was able to just granulate straight out. Also it was pretty good quality black powder.
