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.
The relationship between grinding energy requirement and free lime content of the clinker is logarithmic, where energy increases with increasing free lime content. 4. Grinding energy is related with SM and L p contents of the clinkers by second-order polynomial equations.
Clinker grinding uses a lot of energy and the cement becomes hot - this can result in the gypsum becoming dehydrated, with potentially undesirable results - see the link at the bottom of this page for more information. Inside a (stationary!) cement mill. The part-ground clinker and steel grinding media are clearly visible.
Abstract. Fifteen commercial Portland cement clinker samples with a wide range of chemical compositions were subjected to grinding tests and relationships between grinding energy requirement attained specific surface areas and various chemical parameters were found. Regression analyses of the test results revealed that the energy–fineness ...

crushers, grinding clinker coolers and material handling equipments. The case study suggests that the major sources of CO2 emissions are from the fuel burning and during the clinker production in kiln, which forms a part of the cement production process itself. The study found that 0.613 ton of CO2 is emitted when one ton of clinker's produced.
Concrete production is a large scale process that involves high energy consumption. In order to increase the sustainability of this process, the reduction of energy input is necessary. Bio-glycerol was demonstrated to be a highly efficient renewable-based additive in the grinding process for concrete product
Grinding aids are organic compounds added during the grinding of clinker to prevent cement particle attraction and re-agglomeration, thus resulting in clinker and energy savings which can both lead to reduced CO 2 emissions. This paper seeks to quantify the increase in grinding mill outputs derived from the use of amine or glycol-based GA.
also be used to cool the clinker. The cooling air is used as secondary combustion air for the kiln to improve efficiency since the cooling air has been preheated during the process of cooling the clinker. After cooling, the clinker can be stored in the …
The evaluation of grinding aid (GA) effect on clinker processing in laboratory grinding mills is relatively simple. Yet, the results obtained cannot be directly transposed to industrial mills, given the fundamentally different operational modes and grinding parameters. This paper seeks to evaluate the scale effect by comparing the results obtained from a closed …
Grinding is a highly energy intensive process in the cement industry. Approximately 60 – 70 % of the total electrical ene rgy used in a cement plant is utilised for the grinding of raw materials, coal and clinker.
The clinker grinding stage accounts for approximately 40% of the electric energy consumed in cement production. Because of such a high level of energy demand and the inherent energy inefficiency of conventional ball mill grinding, the cement industry has continually searched for new grinding mill designs and/or grinding system configurations ...
Thermal energy specific consumption of clinker production includes fuels (excluding electricity) used for raw material preparation (grinding, homogenising, drying or slurrying) and pyroprocessing of raw material in cement kilns …

Energy Use. A cement manufacturing plant requires significant amounts of energy to produce clinker, the main ingredient in cement. Energy in the form of electricity is required to prepare the raw meal (typically limestone, clay, sand and iron …
The hardness of clinker is important for the energy cost of the grinding process. It depends both on the clinker's mineral composition and its thermal history. The easiest-ground clinker mineral is alite, so high-alite clinkers reduce grinding costs, although they are …
every year [1]. Cement industries consume 5% of the total industrial energy utilised in the world [2]. A total of 40% of the total energy consumption of a cement plant is used in clinker grinding in a ball mill to produce the final cement product [3]. Figure1shows the percentage of energy usage in various stages of the cement manufacturing ...
The cooled clinker is a kind of granular material with different particle size. They will be ground in the grinding mill to reach the qualified fineness of cement product. During the grinding, 2-3% gypsum powder is added as retarder so that when cement contacts with water, its solidification speed will not be too fast.

Grinding of clinker is the last and most energy-consuming stage of the cement manufacturing process, drawing on average 40% of the total energy required to produce one ton of cement. During this stage, the clinker particles are substantially reduced in size to generate a certain level of fineness as it has a direct influence on such
Grinding energy was approximately 50 per cent of the ball mill and the drying capabilities allowed direct processing of materials of up to 20 per cent moisture content. The main energy issue was the high power consumption of mill fans, with pressure drops of 100mbar not uncommon with high nozzle ring velocities (>70m/s) and internal mill ...
Energy requirements for finish grinding can vary from about 33 to 77 kWh/ton depending upon the nature of the clinker. Several materials such as glycols, alkanolamines, aromatic acetates, etc., have been shown to reduce the amount of energy required and thereby improve the efficiency of the grinding of the hard clinkers.
energy, such as plastics, they form shallow droplets, i.e. the surface is only partially wetted. 2.4 Reduction in the surface energy of clinker The high surface energy of dry clinker is reduced to a certain level by hydroxylation. Further decrease is only possible through organic grinding aids (e.g. SikaGrind®). Organic additives do also work ...
Grinding of the clinker consumes large quantities of energy and time and it is therefore common practice in the industry to use grinding aids. Grinding aids lower the amount of energy and time needed for grinding by increasing the efficiency of the grinding process.
