nodules of clinker are ground to the consistency of powder. Grinding of clinker, together with additions of approximately 5 percent gypsum to control the setting properties of the cement can be done in ball mills, ball mills in combination with roller presses, roller mills, or roller presses.
Air pollution control measures will be provided to control of emission of dust particles in Clinker/Gypsum Grinding section including raw material handling area and Material Transfer Points to achieve particulate emission below 50 mg/Nm3. The total water requirement of the project will be 150 KLD which will be sourced from ground water.
4. Clinker Cooling:- It recovers up to 30% of kiln system heat, preserves the ideal product qualities, and enables the cooled clinker to be maneuvered by conveyors. The most common are reciprocating grate, planetary, and rotary. Air sent through the clinker to cool it is directed to the rotary kiln where it nourishes fuel combustion [3].

Air Pollution Control Techniques For The Cement Manufacturing Industry: A Case Study For Zimbabwe ... 2.4 Cement Grinding This stage is also known as finish milling. Here the clinker is ground with other materials (which impart special characteristics to the finished product) into a fine powder. ... the kiln system, the clinker cooler, and the ...
The emergence of Portland cement in the 1840s made grinding considerably more difficult, because the clinker produced by the kiln is often as hard as the millstone material. Because of this, cement continued to be ground very coarsely (typically 20% over 100 μm particle diameter) until better grinding technology became available.
precalciner is typically 1.5 kg/t of clinker compared to 4.5 kg/t for the wet process. The NOx emissions can be reduced further to 0.5 kg/t of clinker by after burning in a reducing atmosphere and energy of the gases recovered in a preheater/precalciner. For control of fugitive particulate emissions, ventilation systems should be used in

Partial drying may be accomplished in the mill circuit ... Clinker Burning (V-5)
Units that are well designed, well operated, and well maintained can normally achieve generation of less than 0.2 kilograms of dust per metric tonne (kg /t) of clinker, using dust recovery systems. For control of fugitive dust: (a) ventilation systems should be used in conjunction with hoods and enclosures covering transfer points and conveyors;
(8) CONVEYING SYSTEM TRANSFER POINT means a point where any material including, but not limited to, feed material, fuel, clinker or product, is transferred to or from a conveying system, or between separate parts of a conveying system. (9) COVERED CONVEYOR is a conveyor where the top and side portion of the
