Question

Data Cement Production

a. Actual operating time : 1019 h

b. Cement Production : 93,024 Tons

c. Electrical energy consumed  (mill, pre-grinders included for whole Mill Circuit : 577 mWH

d. Electrical energy consumed (mill motors only, pre-grinders excluded) : 271 mWh

Question

a.Specific Electric Energy Consumption
(mill motors only, pre-grinders excluded) 

b.Specific Electric Energy Consumption (pre-grinders included) for whole Mill Circuit

 

Expert Solution
Step 1

Case a - Mill Motors only, pre-grinder excluded.

The actual operating time is T=1019 hours.

The cement production is A=93024 Tons.

The electrical energy consumed is P1=271 mWh.

Electrical energy consumption is E1

 E1=P1T=271×10-3 Wh1019 h=2.66×10-4 W

The specific electrical energy consumption is S1

S1=E1A=2.66×10-4 W93024 Tons=2.85×10-9 W/tonne
