i.e. total mass of input = total mass of output. A material balance is an accounting for material. Thus, material balances are often compared to the balancing of current accounts. They are used in industry to calculate mass flow rates of different streams entering or leaving chemical or physical processes. 4.2. The General Balance Equation

may be chosen such as mass, or concentrations which can be by weight or can be molar if reac-tions are important. 4.3.1 Total mass and composition Material balances can be based on total mass, mass of dry solids, or mass of particular compo-nents, for example protein. Example: Constituent balance

mass balance around a typical flowsheet for producing one oven dry tonne of pulp. The calculations start at the outlet of the white liquor clarifier by determining the flow of white liquor needed at the digester plus any white liquor required by the pulp mill bleach plant and then calculating the lime required to make that quantity of white liquor.

The main aim of this study was to determine the available heat in the cement kiln exhaust gas subject to different process conditions.

8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.

mass". This law states that matter is neither created nor destroyed in the process and the total mass remains unchanged. The general principle of material balance calculations is to put and solve a number of independent equations involve number of unknowns of compositions and mass flow rates of streams enter and leave the system or process.
