To investigate relationships between various measured variables and ventilation rate, the data were collected from one of the Raw Material ball mill circuits (line 1) of the Ilam cement plant (Figure 1). This plant has 2 lines for cement production (5300 t/d). The ball mill has one component, m diameter, and m length with 240 t/h ...

The primary fuel that is used for this particular cement factory is coal and petcoke. The coal/petcoke ratio is 40/60%, and the caloric values of the fuel are and 33 GJ/t, respectively, for coal and petcoke. The average power supply of the cement plant is MW, whereas the minimum power consumption is MW and the peak load reaches 10 MW.

Average kWh/ton of material ground = 2608/150 = 174 kWh. Power consumption per ton of clinker with a conversion ratio for consumption : 1 = x = 27 kWh/ton. Using 4% gypsum 1 ton clinker = tons of cement. Therefore power consumption per ton of cement = ~ kWh.
