• Energy constitutes a significant portion of the cost of steel production, from 20% to 40%.2, 3 Thus, improvements in energy efficiency result in reduced production costs and thereby improved competitiveness. • The energy efficiency of steelmaking facilities varies depending on production route, type and quality of iron

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 mass and energy going into the box must balance with the mass and energy coming out. Figure 2.1. Mass and energy [email protected] The law of conservation of mass leads to what is called a mass or a material balance. Mass In = Mass Out + Mass Stored

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.

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.

energy balance in the mill An energy balance and thermodynamic work relationships can be used to derive practical design equations for a mill. These equations can be used to size a high-capacity, single-pass hammer mill for plant-scale processing of a low-melting organic solid, or other heat sensitive material.Author:Michael T. SearfassPublish Year:2007
