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.

The model is based on the energy and mass flows in the mill. This research builds on the earlier work by Moys et al [1] who estimated the density of the mill discharge through an energy balance model around the mill discharge sump. In another study, Kapakyulu [2] modelled mill temperature based on an energy balance approach around the mill.

Energy balance. The First Law of Thermodynamics for a steady-state flow process can be expressed by the following equation [3]: (1) Δ H + Δ u 2 2 + g Δ z = Q - W s In this expression Δ H is the change in enthalpy of the process, Δ u2 /2 is the change in kinetic energy, and g Δ z is the change in potential energy.

The energy balance takes into account the different energy streams : -air -steam -condensates sheet. Else than these "standard" mass and energy balances, around different sub-systems, we gave the possibility of defining and computing more global balances around several "appara tus", for example the first dryer and its connected heat ...
Analyzing energy balance, we could operate the KP mill using black liquor only, if we save the energy by 6.6%. Case studies of save the energy which we are trying now, shows as follows ; (1) Making higher black liquor consistency. (2) Much more usage of cheaper electric power during the night time.
A dynamic model is developed for a wet overflow ball mill based on a set of mass and energy balances to simulate the mill. The energy balance relies on temperature and mass flow data. The key control parameters to be measured are mill temperature (feed and discharge streams), mill power draw and the mass flow rate in the feed stream.
