Mill ventilation is important for cooling the mill, removing moisture and improving mill efficiency. Typically, a velocity across the media of 1m/s is a good target. The challenge is to measure it. Cement producers are required to measure and report to government agencies about the air that flows up the cement mill stack.

Cement manufacturing - brief description of a cement mill. Cement clinker is usually ground using a ball mill. This is essentially a large rotating drum containing grinding media - normally steel balls. As the drum rotates, the motion of the balls crushes the clinker. The drum rotates approximately once every couple of seconds.

Careful attention must be paid to the alignment and balance of the fan to ensure proper operation. Control and monitoring: ID fans in a cement plant are typically controlled and monitored using a variety of sensors and control systems. These may include temperature sensors, pressure sensors, flow sensors, and vibration sensors.
Raw mill exhaust fans or stack fans are also called as de-dusting fans. In cement industry raw mill exhaust fans handle 2.2 ton of exhaust gases for the production of 1 ton of clinker. Raw mill exhaust fans are operated with very adverse situations because the fan handles mainly gases such as CO2, N2, NOx and Sox along with some dust particles.
This example shows the resultant savings for only one relatively small kiln. There have been reports where up to a million dollars annually have been saved on larger kilns after extensive modifications were made on …
