sciencedirectWhy do we need pyroprocess to make clinker?It's taken us since 1856 to become the experts we are today. The pyroprocess is the central element to the clinker-making process. Without heat – and lots of it – the raw meal would not react to create the cementitious material that is so important to modern life. But creating the temperatures required to form clinker comes at a cost.Pyroprocessing
