Cement manufacturing is an energy intensive process, requiring high fuel consumption for the operation of cement kilns, which in turn generates carbon dioxide (CO2). In addition, CO2 is generated from the chemical conversion of limestone to clinker3 and from the production of electricity for other parts of the process where electricity is used. Technological development in recent decades has led to some technologies that increase the energy efficiency of a cement plant (thus reducing CO2 emissions per unit of cement produced) or significantly decrease hazardous air pollutants (e.g., particulate matter, nitrogen oxides) and therefore, its overall environmental impact. In spite of these environmental improvements, not all CO2 emissions originating from cement plants can be abated with existing technologies.4 As a result, cement plants are significant contributors to global climate change, representing some 5% of global anthropogenic sources.
Manufactures and exports cement plants, cement machinery, cement making machinery, cement plant machinery, ball mills, vibrating screens, vertical shaft kilns, rotary shaft kilns, mill headers, trunnion bearings, bucket elevators, screw & belt conveyors.As a heated pivoting part, cylinder is made of highquality carbon steel plate and supported on the support device by wheel belt. There is mechanical or hydraulic pressure catch wheel on the first or several support device in order to control the turning of cylinder. Gears make cylinder rotate according to processrequired rotating speed through the ring gear in the middle of cylinder. Because of the need of installation or maintenance, the bigger rotary kiln has auxiliary rotary gears, which makes cylinder gyrate more slowly. To prevent enter of cold air and dust overflow, the reliable kiln tail and head sealing equipment are installed on feed and discharge end.
