dry raw materials during the grinding process. An environmental benefit of this process is the reduction of SO2 emissions and other pollutants, such as total hydrocarbons, acid gases such as HCl, NH3 and Dioxins/ Furans. As inline raw mills are not always operational, cement plants can exhibit variability in emissions. This

When envisioning the cement plant of the future, it is important to understand the reference for a typical plant today. Our reference plant is a fivestage preheatercalciner kiln with a vertical raw mill and two cement ball mills. It has an annual production capacity of one million metric tons of cement and produces several types of cement.
The cement plant has two stacks using coal to operate, Raw mill 1 and Raw mill 2. Raw mills are the place where crushed raw materials are mixed and stored for homogenization. 27 We used data from raw mills to measure emission sources.

The consumption of the energy in the cement plant is mainly due to raw mill, cooler, preheater and rotary kiln [14]. The total energy loss of the plant is generally accounted for about 3539% of the total energy input [15]. This energy loss is due to the loss from the exhaust gas, cooler and the radiation heat transfer from the kiln cell.
The solid (kiln feedraw meal) mixed with the gas flow below in each mixer; assumed heat exchange in the process. The mixture was sent to a cyclone and separated. The temperatures of the gas and solids assumed the same in each cyclone stage. The efficiency of each cyclone is set to reflect the dust emission of the reference cement plant studied.
