Customized Cement Manufacturing Plant Rotary Kiln Furnace Energy Saving
Cement kilns are used by the cement industry in the production of cement. Portland cement, used in almost all construction applications, is the industry's primary product. Essentially all of the NO2, emissions associated with cement manufacturing arse generated in the kilns because of high process temperatures.
To make cement, raw materials such as limestone, cement rock, sand, iron ore, clay and shale are crushed, blended and fed into a kiln. These materials are then heated in the kiln to temperatures above 2900°F to initiate a chemical reaction (called "fusion") that produces cement "clinker," a round, marble-sized, glass-hard material. The clinker is then cooled, mixed with gypsum and ground to produce cement.
Nearly all cement clinker is produced in large rotary kiln systems. The rotary kiln is a refractory bricklined cylindrical steel shell equipped with an electrical drive to turn it at 1-3 rpm, through which hot combustion gases flow countercurrently to the feed materials. The kiln can be fired with coal, oil, natural gas, waste or a combination of these fuels. Currently, most cement plants (over 75 percent) are coal-fired.
The rotary kiln from china professional manufacture Hongji Group Machinery is a cylindrical vessel, inclined slightly to the horizontal, which is rotated slowly around its axis. The material to be processed is fed into the upper end of the cylinder. As the kiln rotates, the materials gradually move down towards the lower end, and may undergo a certain amount of stirring and mixing. Hot gases pass along the kiln sometimes in the same direction as the process material (co-current), but usually in the opposite direction (counter-current). The hot gases may be generated in an external furnace, or may be generated by a flame inside the kiln. Such a flame is projected from a burner-pipe (or 'firing pipe') which acts like a large burner. The fuel may be gas, oil or pulverized coal.
