The cement kiln Understanding Cement

However, new cement kilns are of the 'dry process' type. Dry process kilns. In a modern works, the blended raw material enters the kiln via the pre-heater tower. Here, hot gases from the kiln, and probably the cooled clinker at the far end of the kiln, are used to heat the raw meal. As a result, the raw meal is already hot before it enters the kiln.

Kiln heat up time Page 1 of 1 International Cement

Re: Kiln heat up time The rate of heating (and cooling) of the refarctory lining of the burning zone should not exceed 50 degrees C per hour. Below 900 degrees C the rate of heating should be lower at 25 to 30 degrees C per hour. It is unusual to monitor this rate of heating by the temperature in the burning zone.
