Rotary Kiln Introduction:

Rotary kiln is widely used for mechanical, physical or chemical treatment of solid materials in many production industries such as building materials, metallurgy, chemical industry, environmental protection and so on. It is first applied in cement production line. In 1824, British cement worker J'Asp invented the intermittent vertical kiln. In 1883, the German Ditz invented the continuous operation of the multilayer shaft kiln. In 1885, the British Lansam (ERansome) invented the rotary kiln. After obtaining the patent, the United States put it into production and soon gained considerable economic benefits. The invention of rotary kiln makes the cement industry develop rapidly. At the same time, it also promotes the research of rotary kiln application, and soon it is widely used in many industrial fields, and becomes more and more important in these production, and becomes the core equipment of the corresponding enterprise production. In the application field of rotary kiln, cement industry has the most quantity.

Working Principle:

When working, the main drive motor transfers power to the open gear device through the main reducer to drive the rotary kiln. Materials from the end of the kiln (the high end of the cylinder) into the kiln calcinations. Due to the inclination of the cylinder and the slow rotation, the material rolls along the circumference direction and the axial direction (from the high side to the low end), and the clinker is formed through the kiln hood to be cooled by the cooler. The fuel is injected into the kiln by the kiln head, the waste gas produced by combustion is exchanged with the material, and the fuel is derived from the kiln tail.
