Apr 01, 1999· The energy consumption in the cement mills varies between 16.5 to 63.5 kWh/ton with an average of 36kWh/ton . There are numerous factors affecting the energy consumption during clinker grinding. Clinker hardness imparts a wide variation to grindability. The hardest clinker takes about 80% more power than the softest one . Furthermore, different
Clinker and gypsum, being mixed together in predetermined proportions, are fed to the grinding mills. Chemical gypsum, if used instead of natural gypsum, needs to be dried either by natural sun drying or by mechanical drying, before it is used with cooled and dried clinker for inter grinding in mills.
Feb 21, 2019· The value KS K of ordinary Portland cement is 90-95% and 95-98% of high strength Portland cement. The higher value KS K, the lower the grindability. In addition to the physical and chemical characteristics of clinker, the required grinding degree (grinding fineness) also affects grinding balls deterioration.

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.
Clinker Cement; 1: Clinker is a nodular material which is used as the binder in cement products. Cement is a binding agent that sets and hardens to adhere to building units such as stones, bricks, tiles etc. 2: Clinker is a granular substance containing spherical pellets of diameter 3-25 mm.

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 value KS K of ordinary Portland cement is 90-95% and 95-98% of high strength Portland cement. The higher value KS K, the lower the grindability. In addition to the physical and chemical characteristics of clinker, the required grinding degree (grinding fineness) also affects grinding balls deterioration.

The questions of Portland cement clinker grinding in closed circuit ball mills. Noted that the main task of modeling the grinding process is predicting the granulometric composition of the finished product taking into account constructive and technological
Reducing water injection into the mill on grinding table leads to a direct impact on cement strengths. When combined with CHRYSO ® ICARE chemical activation, clinker factor can be pushed on the higher side (+2% further than conventional solutions) without impacting cement quality (Table 1).
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.
Step 6 : Finish Grinding. The clinker is ground in a ball mill—a horizontal steel tube filled with steel balls. As the tube rotates, the steel balls tumble and crush the clinker into a super-fine powder. It can now be considered Portland cement. The cement is so fine it will easily pass through a sieve that is fine enough to hold water.
