Rotary Kiln belongs to building material equipment, calcination rotary kiln is the main equipment in sintering dolomite, which can be divided into cement rotary kiln, metallurgy chemical rotary kiln and lime rotary kiln according to different materials.
Product feature:
1. Support device of rotary kiln: Advanced shaft structure, automatic temperature measuring device and electrical heating device.
2. Catch wheel of rotary kiln: Including mechanical wheel and hydraulic pressure
3. Gears of rotary kiln: Single or double. The rotating speed is controlled by regulating motor, DC motor or variable frequency and speed regulation motor. Be reliable, energy-saving and efficient.
4. Cylinder tyre bolster of rotary kiln: Lower bolster has three types: Fixed, zoom and floating. Its structure is simple, replacement is convenient and it won't hurt cylinder when it needs a change.
5. Sealing equipment of rotary kiln: There are many kinds for choice according to kiln models, including air cylinder edge sealing, spring edge sealing, graphite block sealing and combination for above. The feature is adaptive for cylinder rotating and swing. And sealing effect is very good.
6. Rotary Kiln head hood: Including stationery type and flexible type.
Rotary Kiln is used for:
1. Calcination of high aluminum vandal ochre in refractory material industry;
2. Calcination of calotte and aluminum hydroxide in aluminum manufacturer;
3. Calcination of chrome sand ore and chrome powder ore in chemical plant.

Work principle
The rotary kiln from china professional manufacture Hongji Group Machinery is a cylindrical vessel, inclined slightly to the horizontal, which is rotated slowly around its axis. The material to be processed is fed into the upper end of the cylinder. As the kiln rotates, the materials gradually move down towards the lower end, and may undergo a certain amount of stirring and mixing. Hot gases pass along the kiln sometimes in the same direction as the process material (co-current), but usually in the opposite direction (counter-current). The hot gases may be generated in an external furnace, or may be generated by a flame inside the kiln. Such a flame is projected from a burner-pipe (or 'firing pipe') which acts like a large burner. The fuel may be gas, oil or pulverized coal.
