YUFENG-Metallurgical Rotary Kiln

Metallurgical Rotary Kiln

Rotary kiln is composed of cylinder, gears, support device, kiln liner and kiln tail sealing equipment, kiln head hood and fuel device.

As a heated pivoting part, cylinder is made of high-quality carbon steel plate and supported on the support device by wheel belt. There is mechanical or hydraulic pressure catch wheel on the first or several support device in order to control the turning of cylinder. Gears make cylinder rotate according to process-required rotating speed through the ring gear in the middle of cylinder. Because of the need of installation or maintenance, the bigger rotary kiln has auxiliary rotary gears, which makes cylinder gyrate more slowly. To prevent enter of cold air and dust overflow, the reliable kiln tail and head sealing equipment are installed on feed and discharge end.

Rotary Kiln Product application:

Rotary kiln is a kind of thermal equipment, heating materials. It is widely applied in the fields of cement building materials, nonferrous metallurgy, ferrous metallurgy, refractory material, chemical materials and paper making.

Rotary Kiln Product feature:

1. Support device: advanced shaft structure, automatic temperature measuring device and electrical heating device.

2. Catch wheel: including mechanical wheel and hydraulic pressure catch wheel.

3. Gears:  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: 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: 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. Kiln head hood:  including stationary type and flexible type.

Rotary Kiln working principle:

The kiln is a cylindrical vessel, inclined slightly to the horizontal, which is rotated slowly about its axis. The material to be processed is fed into the upper end of the cylinder. As the kiln rotates, material gradually moves 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 bunsen burner. The fuel for this may be gas, oil or pulverized coal.

Rotary kiln belongs to building material equipment, which can be divided into cement kiln, metallurgy chemical kiln and lime kiln according to different materials.

Cement kiln is used for making of cement clinker and there are dry and wet methods to make cement. Metallurgy chemical kiln is used for magnetic roasting of iron ore and oxidizing roasting of chrome and nickel in the steel factory; baking high-alumina mine in the refractory material factory; baking chamotte and alumina in the aluminum factory and baking chrome ore and chrome powder in the chemical plant.

Lime kiln is used for baking active lime and dolomite in the steel factory and ferroalloy factory.
