Rotary kiln refers to rotary calcining kiln (commonly known as rotary kiln), which belongs to cement building materials equipment and is widely used in cement, metallurgy, building materials, chemical industry, environmental protection and other fields. It has simple structure, high operation rate, convenient and reliable production process control, and kiln products. High quality and less wearing parts. Rotary kilns are divided into variable-diameter rotary kilns and full-diameter rotary kilns according to their appearance, and can be divided into cement kilns, metallurgical chemical kilns and lime kilns according to different materials to be processed. Cement kilns are mainly used for calcining cement clinker, which can be divided into two categories: dry production cement kiln and wet production cement kiln. Metallurgical and chemical kilns are mainly used for magnetization roasting of lean iron ore in iron and steel plants in the metallurgical industry; oxidative roasting of chromium and nickel-iron ore; roasting of high-alumina bauxite in refractory plants and clinker and aluminum hydroxide in aluminum plants; roasting of chromium ore in chemical plants And minerals such as chromium ore powder. Lime kiln (active lime kiln) is used for roasting active lime and lightly burned dolomite used in iron and steel plants and ferroalloy plants. Users can choose suitable equipment types according to actual material needs.
100% product on-site real shooting, so you can rest assured of your choice!
The two ends of the rotary kiln are sealed with combined stainless steel scales, which ensures the reliability of the seal and makes the air leakage coefficient less than 10%.
The kiln body has a certain inclination to the horizontal, and the whole kiln body is supported by a supporting wheel device, and there is a stop wheel device to control the kiln body moving up and down, and the user can flexibly control the kiln body
The transmission part is equipped with a main transmission device, and also an auxiliary transmission device to ensure that the kiln body can still rotate at a slow speed and prevent the kiln body from deforming when the main transmission power supply is interrupted.
The rotary kiln basically does not make any noise during the working process, so its energy consumption is low.
The main structure of the rotary kiln is composed of kiln head, kiln tail, cylinder, supporting device, motor, driving device and so on. Among them, the support device is 3 sets of rollers, the kiln tail is equipped with an enlarged belt, and the inner lining of the cylinder is made of high-alumina bricks and magnesia-chrome bricks. The rotary kiln is a cylindrical object with a certain slope, the slope is 3-3.5%. The rotation of the kiln is used to promote the mixing of materials in the rotary kiln, so that the materials are mixed and contacted to react. The combustion of coal injection at the kiln head produces a large amount of heat, which is transferred to the material through the radiation of the flame, the convection of the hot gas, and the conduction of the kiln bricks. The material moves forward in the kiln depending on the inclination of the kiln shell and the rotation of the kiln.
