Approximately 6.5 xlO9 Joules (5.6 xlO6 Btu''s) are required to manufacture 1 Mg (1 ton) of clinker in a wet process portland cement plant. In a dry process plant, only 4.6 xlO9 Joules (4 xlO6 Btu''s) are needed. The added coal required in wet process kilns increases the S02 emission potential.

In dry and semi dry processes for manufacturing of cement, the raw materials are crushed and fed in the correct proportions into a grinding mill. The raw materials are dried and reduced in size to a fine powder in to grinding mill. The dry powder is called the raw meal. The raw meal is pumped into a blending silo.
