design equation for hammer mill

Energy balance and design equation for the milling of

2007-9-1  To model the behavior of a three-phase stream involving a change of state, an energy balance is derived and then reduced into a practical design equation for a hammer mill. A combination of experimental data, known physical properties, and classical thermodynamic relationships are used to relate processing rate to energy input to the mill.
