The low final clinker temperature is achieved by the application of an appropriate air volume, as well as by a lower height of the clinker bed in the second part (cooling zone
Once the clinker is formed in the rotary kiln, the melted material must be cooled rapidly to maintain product quality. After getting cooled, the clinker now can be safely handled to be stocked in clinker silos. At the final stage, the cooled clinker is ground to find acceptable Blaine.
Additionally, the wear and tear on equipment such as grinding mills and crushers is higher when processing harder clinker, leading to maintenance and replacement costs. Therefore, choosing clinker with optimal hardness can improve the overall efficiency of cement production processes by reducing energy consumption and …
According to Clinker Supplies' Karl Pfeffer, apart from the numerous advantages of the HAZEMAG primary crusher, one of the principal reasons he invested in the HAZEMAG AP-PH 1415 was because the jaw crusher could not handle the volume and size of rocks that it was being fed.
Step 3: clinker cooling. Clinker cooling is the final step in clinker production. This process aims to recycle heat, preheat the secondary air, and improve the quality and grindability of the clinker. Besides, the rapid cooling of the clinker in this process is convenient for cement storage and transportation. Clinker Cooler

• The singer hit a real clinker in the last verse. • In the early days ordinary mill-stones were used as the clinker was soft and the cement need not be finely ground. • This was achieved by initially breaking the clinker with stone crushers before grinding. • Once the firing was completed the clinker was broken out and carted away to ...
The crushing segments has a wear lifetime of at least 3 years and have been known to last more than 5 years, thereby a low maintenance. ... By installing the clinker crusher near to the middle of the cooler we can ensure that the crushed clinker has time to cool properly before leaving the cooler.
intermediate roll crusher is effectively cooled on the second grate and the extracted heat is transferred to the cooler exhaust air. The air blast units installed in the inclined aeration surface of the static pre-grate very effectively eliminate fritted heaps of clinker (so-called „snowmen") before they can become a problem. 6 7
The kiln operator has basically two control variables for accomplishing the above-mentioned objectives: the speed of the bed grates which alters the clinker residence time and the clinker bed depth in the cooler, or the air …
f)Cooler control settings should be such that bed grates, cooler drive unit. clinker crusher, and cooler walls cannot become overheated. The kiln operator has basically two control variables for accomplishing the above-mentioned objectives: the speed of the bed grates which alters the clinker residence time and the clinker bed depth in the ...
The clinker is an intermediate product in cement production before adding additives to cement (Rahman et al., 2013). Because of the high-water content, a massive amount of thermal energy evaporates the moisture from the raw meal. ... The last step is the upgrading of liquids and the ... that concrete crusher sand can serve as an alternative ...
Clinker is the result of chemical reactions that take place in the sintering area and produce a product with the right chemical and molecular composition. After that, air is blown through the clinker to cool it down and give it the right chemical structure. Before being stored or milled, this final clinker is crushed by clinker hammer crushers.
