1.Introduction of ceramic sand rotary kiln
This series of rotary kiln is the large-size advanced international calcining kiln & furnace which is developed by our company and many scientific research institutes such as Beijing General Reserch Institute of Mining & Metallurgy, Changsha Research Institute Of Mining & Metallurgy, Suzhou Sinoma Reserch Institute of Non-metallic Mining Industry, etc. Compared with the rotary kiln with the same specification made by the traditional technology, this series of torary kiln can make the production capacity increase by 30%, make the heat consumption reduce by 40% and make the discharged flue gas temperature<250 °C , so it is convenient for collecting dust and meeting the modern environment protection needs about energy saving and consumption reducing. This rotary kiln is widely used for extracting nickel from laterite, calcining the activated limestone, oxidized pellet, magnesium oxide, aluminum oxide, titanium dioxide, etc.
2.Application of ceramic sand rotary kiln :
Rotary kiln price is the Thermal Equipment, heating materials, in cement industry for calcining clinker.It is also used in various industries, such as cement, nonferrous metallurgy, ferrous metallurgy, chemistry, building, refractory material, environmental protection, etc.
3.Working Priciple of ceramic sand rotary kiln :
The 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.
