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 kiln stage.

Rotary Cooler: rotary cooler is the earliest used one in the cement plant.It is similar to the cement rotary kiln in appearance and equipped with refractory lining and material lifting device inside. The high-temperature clinker enters into the cylinder from one end, contacts with the cold air from the other end under the action of the lifting device, meanwhile carries out heat exchange.

As the grinding process requires a significant amount of power, finer grinding for the 53-grade OPC requires more power and is therefore priced higher compared to lower grades of OPC. Chemical Composition: This a very high strength cement & this is obtained because of very high percentage of C3S content in the clinker about 52-53%.95% clinker ...

A 10 MW cement mill, output 270 tonnes per hour. A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement. Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.

Cyclone preheaters are also called suspension preheaters. In the new dry process of cement manufacturing, the raw meal must be preheated in the preheater before entering the rotary kiln for calcining.The quality of the preheater in a cement plant directly affects the stability of calcining temperature and cement clinker quality in the kiln.

The clinker ring is in the process of calcining clinker, and the amount of liquid phase appears in the temperature range is too large, so that the mature material ring is formed. When the circle is far away from the lower feed port, it can not exhaust the air, and does not reduce the feed amount. Just pull out the coal injection pipe and burn it.

According to the needs of different customers, there are two types of cement ball mill: open-flow mill and circular-flow mill. The φ3.8×13 cement ball mill with double-sliding structure solves the problem of the similar product "the discharge end slide bearing temperature is too high to operate continuously", which ensures the equipment can run continuously and stably for a long time and ...

In the surveyed cement plant, three balances are established between input and output material in the raw mill, clinker production, and cement grinding system. 2.48 t, 4.69 t, and 3.41 t of materials are required to produce a ton of the product in raw material preparation, clinker production, and cement grinding stages; waste gases account for ...

Introduction Cement is manufactured by heating a mixture of ground limestone and other minerals containing silica, alumina, and iron up to around 1450 C in a rotary kiln. At this temperature…

temperature causes the raw material to react and form a hard nodular material called "clinker". Clinker is cooled and ground with approximately 5 percent gypsum and other minor additives to produce Portland cement. The heart of clinker production is the rotary kiln where the pyroprocessing stage occurs.

Composition of the most common type of cement: 85% clinker, 1.5-3.5% gypsum by SO 3 content, and up to 15% admixtures. 5. The primary use of cement clinker is to manufacture cement. Cement is used in construction to make concrete as well as mortar and to secure the infrastructure by binding the building blocks.
