  • Dec 23, 2013· Particle size, number of balls, particle density, hardness, number of media used, time of grinding, and speed of the ball mill (rpm) are factors which will affect the process of milling. Size: The smaller the media particles, the smaller the particle size of the final product.

  • 2 Milling 4 2.2 Milling kinetics The changing particle size distribution of the milled good as a function of time is most easy to characterize qualitatively if the material has initially only one particle size.

  • In ball milling, the desired particle size is achieved by controlling the time, applied energy, and the size and density of the grinding media. The optimal milling occurs at a critical speed. Ball mills can operate in either a wet or dry state.

  • • Ball milling produces a fine particle with a less-controlled distribution Each of these technology categories have substantially different operating variables and applied technology principles. Experts in these fields are able to exploit the capabilities of each category to …

  • Besides particle size reduction, ball mills are also widely used for mixing, blending and dispersing, amorphisation of materials and mechanical alloying [1, 49, 51].

  • The particle size was investigated by varying (i) the speed of the mill from 200 to 400 rpm with regular interval of 50 rpm, fixing the milling time at 30 h, and (ii) the milling time from 15 to 40 h, at a fixed speed of 300 rpm.
