To achieve good combustion and satisfactory flame formation, coal needs to be dried and ground to a proper degree of dryness and fineness. Drying of moisture in coal is achieved normally by ducting part of the kiln exhaust gas through the mill with inlet temperatures of up to 300°C. Inert kiln exhaust gases with oxygen content of about 35% ...

To control the temperature in the cement mill, the first step is to control the the material temperature in the mill, and the temperature should be controlled at room temperature, preferably not more than 50 ℃. When the grinding temperature is high, the majority of mechanical energy will be transformed into heat energy, thus resulting in ...

There are three steps of the hightemperature system: Drying or preheating, calcining, and sintering. The calcining is the core part of the clinker production; the raw meal is weighed and sent into preheater and cement kiln to process clinker. Grate cooler helps to cooler clinker, the cooled clinker is sent to the cement silo for storage.

It has been established that about 710% of the cement can be lost due to uncontrolled emissions in the cement mill [ 21 ]. Some studies show that 45% of dust emissions are due to the furnace's supply, while other dust emission sources are crushers, clinker coolers, grinding, and material handling equipment [ 35 ].
