With rotary kiln used for ore beneficiation operations originated in the field of cement production, in nineteenth century, the world's first tire intermittent earth kiln was born in England, which is what we call the predecessor of the rotary kiln. After 60 years of improvement, in 1885 the world's mineral processing industry landmark equipment - rotary kiln formally was born.
The birth of rotary kiln provides a development opportunity for the early cement production and even the entire industrial area. With the deepening development of the industrial revolution, the rotary kiln was to be improved and applied to an industrial area, as the mineral processing industry is the survival and new facilities. Rotary kiln equipment participate in the most field is the cement industry. Rotary kiln can be defined as the central nervous system of cement production, and plays an indispensable role in the whole cement production process. Cement rotary kiln work can be broadly summarized as "two grinding and one burning."
In addition, rotary kiln keeps great powder in the field of cement production, more are used in, such as limestone and refractory materials the production project. Especially for the refractory production process to design a set of practical processes to ensure its size standardization, strength and molding rate are greatly improved. In the 1960, the Americans also invented the rotary kiln production of phosphoric acid new technology. The advantages of this method are many advantages, such as low energy consumption, less electricity consumption, no sulfuric acid and available middle and low grade phosphate rock, and will soon be popularized in the mineral processing field all over the world.
In addition to the above advantages, in the environmental protection, the world's developed countries, the usage of cement rotary kiln incineration of hazardous waste, waste has been more than 20 years of history, which not only reduce waste, harmless, waste generated can help combustion, saving the energy, the development of circular economy is another vivid illustration.
