Calcining kiln refers to rotary calcining kiln (commonly known as rotary kiln), which belongs to building materials equipment category. Rotary kilns can be divided into cement kilns, metallurgical chemical kilns and lime kilns according to different materials. Cement kilns are mainly used for calcination of cement clinker, divided into two categories: dry production cement kilns and wet production cement kilns. Metallurgical chemical kilns are mainly used for the magnetic roasting of lean iron ore in metallurgical industry; oxidation roasting of chromium and nickel iron ore; roasting high alumina bauxite ore in refractory plants and roasting clinker and aluminum hydroxide in aluminum plants; roasting chrome ore in chemical plants And chrome ore powder and other minerals. Lime kiln (i.e. active lime kiln) is used to roast active lime and light-burned dolomite used in steel plants and ferroalloy plants.
Rotary kiln (rotary kiln, titanium dioxide kiln, sintering furnace, industrial furnace kiln, kiln, oxidation pellets, metal magnesium kiln,). Rotary kiln is the main equipment for calcining cement clinker and has been widely used in cement, metallurgy, Chemical and other industries. The equipment consists of a cylinder, a supporting device, a supporting device with retaining wheels, a transmission device, a movable kiln head, a kiln tail sealing device, a combustion device and other components. The rotary kiln has the characteristics of simple structure, reliable operation and easy control of the production process.
In order to improve the degree of automation, the kiln head uses industrial TV to watch the fire, the process flow simulates the fluorescent screen, and the calcining belt uses an infrared scanner to directly reflect the calcining situation of the calcining belt on the computer. These new technologies are intuitive to use, easy to operate, and reliable to use . The thermal system is stabilized and the equipment operation rate is increased. Compared with the equipment of the same specification, the operation rate has increased by 10%, the output has increased by 5%-10%, and the heat consumption has been reduced by 15%.
