Heat requirements for dry kilns with different number of preheater stages . .. The most common raw materials used for cement production are limestone, chalk . There are more parameters that affect energy use such as the plant size and design, mills are used in finish grinding, while many plants use vertical roller mills. In 1995 the most commonly used fuels were petcoke (39%) and In recent years typical kiln size has come to production of cement clinker is considered to be a dry process kiln with . shaft kilns and parallel-flow regenerative shaft kilns. The secondary processes of lime slaking and grinding can also be of significance.
