clinker at their cement plants. Manufacturers also ship clinker to grinding plants in areas where cement-making raw materials are not available. CLINKER GRINDING MACHINES In the present world there all many machines available to grind the clinker to produce cement. Some of the popular known machines for clinker grinding are listed below ...

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.

This research focused the role to study the effects and ways to control the chemical composition of clinker for better cement production. Cement is a substance produced by grinding a mixture of a clay and limestone and heating to a temperature of 1450°C, in which the chemical transformation occurs inside the kiln to form new compound called clinker.

Current knowledge on clinker grinding was built over the past decades, but contributions from fracture mechanics remained limited. This research aimed to contribute to this field by investigating industrial clinkers with innovative techniques such as multiscale microscratching and statistical electron-probe microanalysis (EPMA).

Keywords Industrial minerals; grinding; particle size INTRODUCTION The use of Portland limestone cements has many benefits, both technical and economical. The European Prestandard prEN 197-1 identifies 2 types of Portland limestone cement containing 6-20% limestone (type II/A-L) and 21-35% limestone (type II/B-L), respectively [ 1 ].

Clinker is produced inside the kiln during the cement manufacturing process. Raw mix is heated and then rapidly cooled to produce the marble-sized pellets of clinker. Read: Clinker Manufacturing Process. Cement is produced by grinding clinker (added with different active ingredients to achieve the desired properties of cement) into a fine powder. 4

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 …
