The design of cyclonic pre-heaters in suspension cement kilns
Cement manufacturing consumes two main types of energy: fuel and electricity. On average, energy costs represent 40% of the total production costs per ton of cement, up to 60% in the case of lime kilns. Over the past years, fuel economy – achieved by better heat recovery – has been counteracted by rising electricity and fuel costs.
