Modern Processing Techniques to minimize cost in Cement

The pre- grinding system is applied if a production increase of 2030 is required. Energy saving of 15 to 20 is achieved depending on material to be ground. With semi-finish grinding an increase in production capacity depends essentially on the size of the high pressure grinding rolls.

Best energy consumptionInternational Cement Review

Cement grinding. For cement grinding the technology development away from ball mills has taken a different route. The development of roller presses in the 1980s took advantage of the benefits of higher-pressure grinding and many presses were retrofitted to ball mills as pregrinders. Ball Mill Ball mills with high efficiency separators have been used for raw material and cement grinding in cement plants all these years. Ball mill is a cylinder rotating at about 70-80 of critical speed on two trunnions in white metal bearings or slide shoe bearings for large capacity mills.

Portland Cement Manufacturing Industry National Emission

Portland cement manufacturing is an energy intensive process in which cement is made by grinding and heating a mixture of raw materials such as limestone clay sand and iron ore in a rotary kiln. The kiln is a large furnace that is fueled by coal oil gas coke and/or various waste materials. As the kiln is considered the heart of the cement plant any failure of heat resisting castings installed in the kiln or directly connected equipment will lead to an immediate plant shutdown. The recent trend to increase the usage of abrasive and corrosive alternative fuels has let us to develop new solutions.
