Brief information about basis of cement assembly line

Cement is probably the most essential materials (bonding agent) inside building industry. It may be produced in a simple process at reasonable cost, the finished technique is not unhealthy for the environment, this means you will be recycled. There has become a significant rise in the utilization of cement over the past several years. The demand is predicted to increase further in the foreseeable future as, particularly in Asia and Latin America, infrastructure measures and housing is going to be intensified. There are double-digit growth rates in cement production mainly in China, but also in India, Indonesia, Malaysia and also the Philippines. Several Middle East and African countries may also be increasing their cement production.

Zenith Machinery, as a limonite ore beneficiation manufacturers, has got to plan the growing interest in bearings employed in machines for cement production. Cement producer vegetation is usually erected near huge limestone deposits. When the geological structure of the limestone is just not homogeneous, additives has to be admixed during the preparation process. Limestone deposits are virtually inexhaustible so your accessibility to this raw material for cement later on is ensured. Limestone, alumina etc. are quarried or mined in quarries or pits and subsequently reduced to sizes which range from 12 to 80 mm. Drying/mixing. The material broken within the crushers is come to drying plants by truck or belt conveyors. Inside drying process the moisture is reduced to approx. 8 to fifteen %, with regards to the further size reduction process. In the drying process, additives can be admixed. The information is then devoted intermediate storage.

State-of-the-art coarse grinding systems are generally vertical roller grinding mills (see section 1.2.4) or roller presses (see section 1.2.5). Because of their slighter energy consumption, methods are gradually replacing ball mill grinding (see section 1.2.6) which are still used, in conjunction with an effect mill or as independent units for coarse grinding. In the coarse-grinding process the last grain sizes of approx. 0.1 mm needed for the further cement production process are produced. Burning the raw meal/cooling the clinkers in so-called cyclone preheating plants and succeeding rotary kilns the raw meal is continuously heated from ambient temperature to approx. 1500��C and discharged as granulated cement clinker.

The burning of raw meal to clinker is really a complex process. It is made of precisely defined steps and is also constantly monitored. Large rotary kilns today can be approx. 6 m across and 100 m long, reaching throughputs up to about 10,000 t per unit and day. The energy carriers employed for preheating and heating in preheating plants as well as for ��burning�� the fabric in rotary kilns are coal, oil and propane. Which of such fuels are ultimately used is determined by their price and availability.
