Energy saving rotary kiln for cement making plant
Rotary kiln introduction
The rotary kiln refers to rotating calcining kiln, which belongs to the class of building materials equipment. Its technical performance and operating condition largely determine the quality of the product, productivity and cost of enterprise. In the building materials industry, apart from the calcination of cement clinker.
Lime kiln are used for the pyroprocessing stage of manufacture of Yuhong and other types of hydraulic cement, in which calcium carbonate reacts with silica-bearing minerals to form a mixture of calcium silicates. Over a billion tonnes of cement are made per year, and cement kilns are the heart of this production process: their capacity usually defines the capacity of the cement plant. As the main energy-consuming and greenhouse-gas–emitting stage of cement manufacture, improvement of kiln efficiency has been the central concern of cement manufacturing technology.
Rotary kiln working principle
Modern plants are composed of 3 key components to acheive high effiency: Cooler, Kiln, and Preheater
The basic components of a calcination rotary kiln are the shell, the refractory lining, support tyres and rollers, drive gear and internal heat exchangers.
The calcination rotary kiln is a cylindrical vessel, inclined slightly to the horizontal, which is rotated slowly about its axis. The material to be processed is fed into the upper end of the cylinder. As the kiln rotates, material gradually moves 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 bunsen burner. The fuel for this may be gas, oil or pulverized coal.
