grinding of clinker and grinding cooling in cement industry

Continuous level measurement for cement clinker coolers

Clinker level in the cooling system The clinker is cooled as it is discharged from the rotary kiln onto a moving grate through which air is forced. The cooling is regulated by the feed rate and the amount of airflow. The quality of the clinker is directly affected by the cooling rate.

CLINKER COOLING TECHNOLOGY

Rapid cooling of clinker is done because of the following reasons. 1. In slow cooling, MgO crystals are formed which, during hydration of cement, form Mg (OH) 2. The hydroxide thus formed occupies 39 times the volume of MgO and hence causing expansion cracks. Rapid cooling will maintain MgO in a glassy state that does not form the hydroxide. 2.

27.07.2021During the cement production process, these minerals are fused together by heating them to just under their melting point, forming a cement clinker between 3 to 20 mm in diameter. Pure cement is formed when the cement clinker is ground into a fine powder. To regulate how cement mortar or concrete will set, gypsum is added to this powder.

Clinker Cooler

The cement clinker after sintering is not the final cement product sold in the market. We need to convey it to the cement mill for further grinding and mixing of gypsum and other raw materials to achieve a certain degree of fineness and different characteristics. Therefore, we need to lower the temperature of the clinker in advance (generally 50

How Is Cement Produced in Cement Plants

After calcination, the cement clinker will enter a cooler for cooling. Phase V: Clinker Cooling Final Grinding. The hot clinker discharged from the rotary kiln is cooled in the grate cooler by forced air, which is extracted from the outer atmosphere by grate cooling fans. The temperature of the clinker after being cooled drops from 1350

Clinker Cooler

Clinker leaves the cement kiln usually at more than 1200℃ and it carries the heat content about 1250-1650 kJ/kg. So it needs to be cooled in order to: improve the cement quality and the grindability of clinker. When the clinker is rapidly cooled, the formation of mineral crystals in it is inhibited.

Clinker size and cement grinding

202128As a general rule, there should be less than 25% of clinker that is below 1mm in size. Coarse clinker is more of an issue for ball mills. Some cement groups use a formula, such as Bond's, to calculate the maximum ball size required in a ball mill, based on the average size of the clinker feed. However, one drawback with this approach is that

Why is supplementary cementitious material in concrete?

During the cement manufacturing process, upon the cooling of clinker, a small amount of gypsum is introduced during the final grinding process. Gypsum is added to control the "setting of cement". If not added, the cement will set immediately after mixing of water leaving no time for concrete placing.
