4.1 Cement Manufacturing: Basic Process and Operation To design the Refractory for the lining of different equipments in a cement plant, it is necessary to understand the total operational process of a cement plant in depth. ... In the cement kiln, all the ingredients are heated to about 1400–1500 °C in huge ...

Quite a few wet process kilns are still in operation, usually now with higher-tech bits bolted on. However, new cement kilns are of the 'dry process' type. In a modern works, the blended raw …

In case of an emergency, such as badly overheated cooler conditions, the kiln operator has two more possibilities to bring the cooler under control: the amount of clinker falling into the cooler can be decreased by slowing tl1e kiln speed, or the temperature of the clinker falling into the cooler can be lowered by adjusting the flame geometry ...

Cement plants stood or fell by the round-the-clock expertise of their kiln operators. From the late 1960s, instrumentation started to improve, and the operator's reliance on visual information was aided by TV cameras mounted on the hood inspection ports.

A brief introduction to cement kiln operation is presented to understand the complexities and challenges of controller design. A literature survey on cement kiln modelling indicates both traditional and intelligent techniques. ... The kiln is very sensitive to control strategies and poorly run kiln can easily double the cement plant operating ...

Fuel Rate is frequently used as a controlling parameter in kiln operation. Fuel is regulated in kiln and precalciner to maintain required temperature. O2 and CO must be considered first before increasing fuel rate. Feed Rate is generally maintained in a stable kiln operation. When the control actions, like kiln speed, fuel rate and air control ...
