Coal is used for heating the raw materials at 1450 degrees centigrade to turn into clinker. The grade of coal supplied in the cement manufacturing industry depends on the grade of limestone used in the cement manufacturing process. If the limestone used in the cement manufacturing process is of high grade then low-grade coal is used and vice versa.
contact us· The strength property of limestone calcined gangue cement with 45% replacement of clinker was higher than reference cement (CEM I 42.5 N) on 7 and 28 days. Furthermore, it is found that the calcined gangue has less influence on the workability of LC 3 according to particle morphology compared with a typical calcined clay, based on the results ...

contact us· To make Portland cement—the most common type of cement—powdered limestone is heated in a rotary kiln. As a source of calcium, it joins with powdered clay to produce a product called clinker, which is then ground with a source of sulfate, like gypsum. It is mixed with water, sand and crushed rock to create concrete.
