Hongxing rotary kiln introduces the internationally advanced technology togather with rich production experience. The price of Hongxing rotary kiln is reasonable. The rotary kiln refers to rotary calcining kiln ( commonly known as rotary kiln) which belongs to the category of building materials equipment. The rotary kiln can be divided into cement kiln, metallurgy chemical kiln and lime kiln according to different materials. The cement kiln is mainly used in calcining cement clinker, which can be divided into sub-dry production of cement kilns and wet process of cement kilns. Metallurgy chemical kiln is mainly used in roasting the depleted iron ore magnetic, oxidizing roasting of chrome and nickel iron ore in steel plants of metallurgical industry. The metallurgy chemical kiln is also used in calcining clinker for high alumina bauxite mine, aluminum hydroxide in refractory plant. The lime rotary kiln (i.e, active lime kiln) is used for roasting steel mills and the active lime and light-burned dolomite for ferroalloy plant.

The rotary kiln consists of a tube made from steel plate, and lined with firebrick. The tube slopes slightly (1–4°) and slowly rotates on its axis at between 30 and 250 revolutions per hour. The cylinder of kiln is made by high quality carbon steel plate, cylinder and rotary department is supported by supporting device through tire. At the middle part of the cylinder Fixed a large gear , the rotation of cylinder is through speed regulating motor--reducer --pinion -- large gear. Materials is feeding through the pre-heater chute to the rotary kiln, because of cylinder tilt and slow rotation, material along the circumference side scrolling, meanwhile moved to kiln head along the axial, Materials has been preheated, decomposed, sintering, then become to calcined dolomite ,and discharging into the cooler from the kiln head. The gas or coal powder as fuel is burning through the burner, the heat will be transferred to material by the flame radiation, the heat convection, kiln brick conduction, etc, material calcined into finished products.

Structure of rotary kiln:

The rotary kiln produced by Henan Hongxing Mining Machinery is rather universal being used in cement production line. Mainly it consists of hovel, tire and roller step wheel. 1. Hovel: the thickness of hovel steel board produced by our company is about 40mm, inside which is a layer of refractory bricks with thickness 20 mm. And the quality of refractory brick will without doubt affect rotary kiln service life. About one-meter cone inlet chamber equipped at the end of rotary kiln, so that materials can smoothly entry into it.

Some large sized mining companies in our country also did some meaning practice in the automatic control aspect of the rotary kiln, mainly by way of examining the thermo technical signals inside the kiln such as temperature, pressure and flow amount of the slurry, on the basis of which, keep the temperature of the burning area in a allowable range with the method of intelligent control. However, because of the limit of the examining means, when designing such control systems, the experts often forget the important information of the moving state of the materials inside the kiln. As a matter of fact, the moving state of the materials has a decisive effect on the energy transmission process of the kiln.
