Rotary kiln is composed of cylinder, gears, support device, kiln liner and kiln tail sealing equipment, kiln head hood and combustion. Cylinder as heated pivoting part, made of highquality carbon steel plate, is supported on the support device by type, and there is mechanical or hydraulic pressure ch wheel on the first or some gear in order to control the turning of cylinder.
· The exhaust gas from the top of the kiln will enter the dust collector and the temperature of the exhaust gas should be kept at 120~150 degrees centigrade.

BartlettSnow™ rotary kiln refractorylined cylinders are supported in two riding rings, each resting on a pair of trunnion rolls. The cylinder is rotated by means of a girt gear and pinion drive arrangement. Both ends of the cylinder are enclosed by stationary breechings with .
· Kiln parts body. kiln body. The kiln body is the main part of the rotary kiln, whose general length can be 30150meters. The kiln body is a cylindershaped with a 35 rolling ring in the middle. Cylinder is always be cut into 310pieces in the workshop then transports by a .
Rotary kilns work by processing material in a rotating drum at high temperatures for a specified retention time to cause a physical change or chemical reaction in the material being processed. The kiln is set at a slight slope to assist in moving material through the drum. Directfired kilns utilize direct contact between the material and ...
· There are two types of rotary kilns which are normally used for the production of lime namely (i) long rotary kiln (LRK), and (ii) rotary kiln with preheater (PRK). Long rotary kilns (LRK) – The LRK (Fig 1) consists of a rotating cylinder upto 150 meters (m) long and inclined at an angle of 1 degree to 4 degrees to the horizontal with a diameter of around 2 m to m.
· Rotary Lime Kiln for Lime Calcination. Limestone rotary kiln is inclined cylinder that can rotate. At the higher end, limestone is fed in. While at the lower end, it is the furnace where a great variety of fuels can be used to burn the limestone, such as coal, gas, oil and so on. For modern lime calcination plant with rotary lime kiln, it is ...
China Active lime rotary kiln production line limestone ... Features The output of the rotary kiln is stable and suitable for large, medium and small active lime production lines. rotary kiln is opentype calcination. rotary kiln can directly calcine 10~50mm finegrained limestone.
Rotary kiln belongs to building material equipment, which can be divided into cement kiln, metallurgy chemical kiln and lime kiln according to different kiln is used for making of cement clinker and there are dry and wet methods to make cement.
While the vertical lime kiln, as its name implies, is a vertical cylinder. And in light with these different forms, rotary lime kiln tends to have larger capacity than the vertical lime kiln. For the lime rotary kiln can be very long while the vertical lime kiln is limited in length due to .
the vertical shaft kiln. This kiln can be described as an upright heavy steel cylinder lined with refractory material. The limestone is charged at the top and is calcined as it descends slowly to discharge at the bottom of the kiln. A primary advantage of vertical kilns over rotary kilns is the higher fuel efficiency. The primary disadvantages of
Wet process kilns. The original rotary cement kilns were called ''wet process'' kilns. In their basic form they were relatively simple compared with modern developments. The raw meal was supplied at ambient temperature in the form of a slurry. A wet process kiln may be up to 200m long and 6m in diameter.
0. is the worlds leading supplier of preheater / rotary kiln lime calcining systems. ''s preheater / rotary kiln systems produce the highest quality lime, with the widest range of stone feed size. Preheater / rotary kiln systems can use gas, oil or coal for firing. Minerals has designs for single line plants up to 1,800 tpd.
· Several rotary kiln designs have evolved, each specific to the process appliion it is intended for. They also come in several forms and shapes. Although the majority consist of straight, cylindrical vessels, dumbbellshaped designs (Figure 1.) take advantage of the benefits that variable drum sizes can bring to process appliion.
Rotary kilns are used to heat solids to the point where a required chemical reaction(s) takes place. The rotary kiln is basically a rotating inclined cylinder. Solids retention time in the kiln is an important design factor and is set by proper selection of the diameter, length, speed, slope and internals design.
Latest drive systems for rotary kilns . The rotary kiln is the core of lime and cement clinker production. In the slightly inclined cylindrical tube, which rotates around its longitudinal axis during the firing process, the lime powder is heated up to 1450 °C and burned into cement clinker.

· 1. Introduction of Rotary Cooler: The singlecylinder rotary cooler is a device that fully heats the hightemperature materials with the air through the rotating cylinder, and cools the materials. It has good cooling effect, large production capacity, high operation rate, energy saving and environmental protection, simple operation and maintenance, and long life of the whole machine.
Rotary kilns consist of a rotating cylinder inclined at an angle of 3 to 4 degrees to the horizontal. Limestone, chalk or Dolomite is fed into the upper ''back end'', and fuel plus combustion air is fired into the lower ''front end''.The product is then discharged from the kiln into a cooler, where it is used to preheat the combustion air.
