4. MATERIALAND ENERGY BALANCE
Figure 4.1: Mass and Energy Balance. The law of conservation of mass leads to what is called a mass or a material balance. Mass In = Mass Out + Mass Stored Raw Materials = Products + Wastes + Stored Materials. Σm R = Σm P + Σm W + Σm S (where Σ (sigma) denotes the sum of all terms). Σm R = Σm R1 + Σm R2 + Σm R3 = Total Raw Materials Σm
Chapter 4 Mass and Energy Balances - CPP
Mass and Energy Balances In this chapter we will apply the conservation of mass and conservation of energy laws to open systems or control volumes of interest. The balances will be applied to steady and unsteady system such as tanks, turbines, pumps, and compressors. 4.1 Conservation of Mass The general balance equation can be written as

Table 1 shows a comparison of the specific energy values calculated from Eqs. () and for the 100 mesh test sieve (S = 150 µm) and seven values of G in the range of 0.33–3 g/rev.It can be seen that at a G value of 1.5 both the equations give the same estimate of the specific energy. For G values greater than 1.5 the Bond equation gives relatively higher …

One way to prevent cement from ending up in landfills after its shelf life is to regain its activity and reuse it as a binder. As has been discovered, milling by planetary ball mill is not effective. Grinding by collision is considered a more efficient way to refine brittle material and, in the case of cement, to regain its activity. There has been considerable research regarding …
