Details+Dec 28 2013nbsp018332Ball Mill is the equipment to be used for sie reduction. It is a kind of grinder used for intermediate or fine grinding. Ball mill is a metal cylinder which rotates about its horiontal axis. The coarse sugar charged along with the metal balls breaks to fine powder by impact of metal balls.

Details+In our research we use the highenergy ball milling technique to synthesie various nanometer powders with an average particle sie down to several nm including nanosied a
Details+Some of the things that you should consider before getting the perfect Ball Mill are the sie and density of the medium or the balls. Lets say for the sie. It is important the sie medium ball is bigger than the biggest particle to be destroyed because otherwise the particle will be hard to be destroyed.
Details+In particular ball milling in dry conditions led to a wider sie distribution since the material was sticking to the surface of the container and formed aggregates due to the presence of surface interactions in the dry state. Particle sie in this case was around 500 nm.
Details+Particle sie range is impact breakage. A standard laboratory ball mill was used to determine breakage and selection functions parameters in Austin model Hasani et al. 2009. 2.2.1 Selection function The variation of specific rate of breakage with particle sie can be fitted by the
