emission load calculation for clinker grindinIn the cement industry, the clinker grinding step consumes about onethird of the power required to produce one ton of cement. This refers to an average specific power consumption of 57 kWh per ton (Seebach and Schneider, 1986) and specific carbon dioxide emissions intensity for electricity generation of CO 2 per ton (Worrel et al, 2000).

Voltage current resistance and electric power general basic .The nominal impedance Z = 4, 8, and 16 ohms (loudspeakers) is often assumed as resistance R. Ohm's law equation (formula): V = I × R and the power law equation (formula): P = I × V. P = power, I or J = Latin: influare, international ampere, or intensity and R = resistance. V = voltage, electric potential difference Δ V or E = electromotive force (emf = voltage).
