[خذ المزيد]2002-1-22 · Sonic velocity, as expressed in Eq.(1), is a function of gas molecular weight (MW), and the gas temperature. (1) Vs =rt(kRT/ MW) The motive gas of a lower molecular weight at higher temperatures will give the higher sonic velocity and, therefore, higher kinetic energy. The gas velocity and their resultant kinetic energy then determine the grinding performance.
