The bigger pieces are then crushed in the hammer crusher. The clinker is then conveyed to the clinker silo by means of shaker conveyor and bucket elevator. There are 2 silos of capacity about 2000 tonnes each. (H) CLINKER GRINDING (CEMENT MILLS) Cement grinding mill is similar to that of Raw mill used for raw material finish grinding.
Cement clinker is a solid material produced in the manufacture of Portland cement as an intermediary product. Clinker occurs as lumps or nodules, usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter. It is produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement …
Clinker is a nodular material produced in the kilning stage during the production of cement and is used as the binder in many cement products. The lumps or nodules of clinker are usually of diameter 3-25 mm and dark grey in color. It is produced by heating limestone and clay to the point of liquefaction at about 1400°C-1500°C in the rotary kiln.
crushers, grinding clinker coolers and material handling equipments. The case study suggests that the major sources of CO2 emissions are from the fuel burning and during the clinker production in kiln, which forms a part of the cement production process itself. The study found that 0.613 ton of CO2 is emitted when one ton of clinker's produced.

As can be seen from Table 2, the clinker grinding time remained high in 2015 compared with the same period in 2014, on the premise that the clinker powder was ground to 350±10m²/kg. After adjusting the raw material fineness control target, the grinding time in 2016 has been on a downward trend and gradually recovered to about 32min.
The preheating and partial precalcining of the raw material are completed by the cyclone preheater, instead of the partial function of the rotary kiln, shorten the length of the rotary kiln, and the gas heat exchange process in the kiln is carried out in a stacked state, and moved to the preheater in a suspended state.Under the process, the raw material can be fully mixed with …
Clinkerization The process of clinkerization signifies conversion of raw meal into clinker minerals mainly consisting of C4AF (Aluminoferite), C3A (Aluminite), C2S (Belite) and C3S (Alite) phases along with small percentage of free lime CaO, MgO, Alkalies, Sulphates etc.

Gypsum is added to clinker primarily as an additive preventing the flash settings of the cement, but it is also very effective to facilitate the grinding of clinker by preventing agglomeration and coating of the powder at the surface of balls and mill wall. Organic compounds are also often added as grinding aids to avoid powder agglomeration.
