History and Operating Principle from the Rotary Kiln

Rotary kiln is also namedindia suppliers of belt conveyor for sand rotary calcining kiln, it belongs to building material gear, and may be divided into cement kiln, metallurgy chemical kiln and based on different components.

The structure of Cement Rotary Kiln is simple, operate conveniently and reliably in life, much less wearing parts, high rate of operation, it truly is the gear to calcine higher(zenith an excellent business for mining and quarry crusher)grade cement in cement plant. Meanwhile, it's also extensively employed in metallurgical, chemical, construction and other industries. The rotary kiln created by my enterprise is with powerful structure, operation smooth, large(zenith a superb firm for mining and quarry crusher)top quality solutions and so forth.

The rotary kiln consists of a tube produced from steel plate, and lined with firebrick. The tube slopes slightly (14) and slowly rotates on its axis at amongst 30 and 250 revolutions per hour. Raw mix is fed in at the upper end, along with the rotation of your kiln causes it gradually to move downhill to the other finish from the kiln. At the other end fuel, inside the form of gas, oil, or pulverized solid fuel, is blown in by way of the "burner pipe", making a large concentric flame in the lower a part of the kiln tube. As material moves under the flame, it reaches its peak temperature, ahead of dropping out from the kiln tube into the cooler. Air is drawn initially through the cooler and after that by means of the kiln for combustion in the fuel. In the cooler the air is heated from the cooling clinker, so that it may perhaps be 400 to 800 C just before it enters the kiln, as a result causing intense and fast combustion on the fuel.

The earliest thriving rotary kilns were developed in Pennsylvania around 1890, and had been about 1.5 m in diameter and 15 m in length. Such a kiln produced about 20 tonnes of clinker per day. The fuel, initially, was oil, which was readily readily available in...
