grindibility vs % C3S & L.S.F. Consequently grinding may get effected with minimum required C3S in clinker and same to be ground finer by consuming more power (kWh/mt) and some reduction in feed rate (mt/hr) also may found necessary.Such impact may not be realized to manufacture cement strength class of 40 to 50 Mpa — generally 80 % of total cement consumption comes under it.

Clinker size and cement grinding. Clinker size is important for the optimization of cement grinding, and is also an indicator of cement quality. Having a high percentage of coarse clinker can be difficult to grind. However, having a high percentage of fine clinker can also be hard to grind and have a negative impact on cement performance.

Portland cement clinker is a hydraulic material which shall consist of at least two-thirds by mass of calcium silicates (3CaO.SiO 2 and 2CaO.SiO 2), the remainder consisting of aluminium and iron containing clinker phases and other compounds.The ratio of CaO to SiO 2 shall not be less than 2.0. The magnesium oxide content (MgO) shall not exceed 5.0% by mass.
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 kiln stage.
The grinding costs of clinker are smaller than this cost difference. Furthermore, if clinker is imported then several types of cement can be produced from that clinker, allowing greater flexibility to meet the specific and possibly changing local market demands.
With these directives, SBICCL was incorporated in Dhaka with an ambitious plan to set up a modern clinker and cement plant which has three critical dimensions: 12,000 TPD Clinker Line; 3,000 TPD Grinding Unit; Long Belt Conveyor of 18 Kms
