The Cement Production Process

The Cement Production Process. Cement kilns are massive cylindrical structures, lined with refractory brick, into which a lime-bearing material and fuel such as coal or gas is fed. There is a range of different kiln designs but all rely on the same basic processes — raw feed passing through the kiln is heated to very high temperatures by the ...
