Energetic evaluation of materials comminution processes

  • Published:
Soviet Powder Metallurgy and Metal Ceramics Aims and scope

Conclusions

An examination is made of simplified models of processes used in the production of powdered materials. A method is proposed for calculating the specific amounts of energy expended in these processes. Data for the comminution of tin are employed to describe the determination of the most energetically favorable processes for various powder particle-size ranges. The advantages are demonstrated of the atomization of a thin molten film compared with atomization with the “focus” of a stream. Milling performance is shown to be improved by the use of lubricant. As the assessment is not comprehensive (being based only on an energy economy criterion), however, the results obtained cannot be employed for examining the effectiveness of real comminution processes.
