Title： Rotary kiln
Kiln in building materials, metallurgy, chemical industry, environmental protection and many other production industries, the widespread use of the rotary cylinder device for solid material mechanical, physical or chemical treatment, such equipment is called a rotary kiln. Rotary Kiln cement production originated in the 1824 British mason J Asp invented intermittent earth kiln operation; 1883 Germany Dietz invented the continuous operation of the world's multi-shaft kiln; 1885 British Lan Samu ( ERansome) invented the rotary kiln, after the British and American patented it into production quickly gained considerable economic benefits. The invention of the rotary kiln, making the rapid development of the cement industry, but also to promote the study of people kiln applications quickly kiln is widely applied to many industries and are increasingly important in the production, the core of the respective producer equipment. In the rotary kiln applications, up to the amount of the cement industry.
1. Its technical performance and functioning, to a large extent determine the quality, yield and cost of their products. "As long as the kiln turn, there are thousands and thousands" This ballad is on the importance of the production of rotary kiln vivid description.
2. The building materials industry, in addition to the rotary kiln calcining cement clinker, but also for calcined clay, limestone and slag were drying; refractories production, the use of rotary kiln calcination of raw materials to dimensional stability, increase strength and then molding process.
3. beneficiation process, rotary kiln to be depleted iron ore magnetic roasting, the ore original weak magnetic changes to ferromagnetic order to facilitate magnetic separation.
4. The chemical industry, rotary kiln production of soda, calcined phosphate, barium sulfide and the like. In the 1960s, the United States and other LapPle invented the rotary kiln production of phosphoric acid new technology. The method has low energy consumption, less electricity, not sulfuric acid and can be used in low-grade phosphate rock advantage.
5. The entire production process of cement summarized as "a two grinding burn", where "a burning" is the preparation of a good raw material milled at high temperature rotary kiln clinker burning process becomes. Thus, the rotary kiln cement production host, commonly known as the cement factory "heart."
6. On the environment, the world's developed countries to use cement kilns burning hazardous waste, garbage has more than 20 years of history, which not only waste minimization, harmless, and will use waste as fuel, saving coal, do waste of resources.
Kiln Category: in accordance with sub-divided into adjustable exterior diameter rotary kiln and rotary kiln, according to zoning can be divided into cement kiln, kiln ceramic sand, kaolin rotary kiln, lime kiln, etc., according to the energizing effect divided into different gas kiln, coal-fired rotary kiln, rotary kiln fuel mix.
1. adjustable rotary kiln
Before and after the change in diameter of the rotary kiln. Usually before and after the change in diameter of about 30cm. More traditional path kiln energy-saving, high yield advantage, but adjustable rotary kiln process is difficult, more difficult than conventional diameter rotary kiln process. Equipment requirements more stringent.
2. diameter rotary kiln
Is the same before and after the diameter of the rotary kiln, rotary kiln our common type, 1883, invented by the German Dietz world. After a hundred years of evolution has become a common rotary kiln equipment. Better results and higher yields than traditional shaft kiln. Processing is simple, just more energy than the adjustable rotary kiln.
