Clinker Production

Bhushan (2010) stated that lowering the clinker ratio can help in reducing the total emissions per ton of cement since both fuel consumption and specific process emissions depend on the clinker-cement ratio. From plant-level data, Gao et al. (2016) found out that 4.69 tons of materials are necessary to produce a ton of product in clinker ...

Clinker coolers get an agile twist

Claudius Peters performed agile sprint cycles to measure the effects of modifications to a clinker cooler, a giant industrial machine used in cement production. Clinker coolers are huge industrial machines — about half the size of a football field — that cool molten rock, called clinker, from 2,550° to 212° F.
