Customerized Design Rotary Kiln for Cement Production Line
Cement rotary kiln:
1. High efficiency
2. Low power consumption
3. Reliable working condition
4. Long service life.
Rotary calcining kiln types:
Rotary calcining kiln belongs to building material equipment, which can be divided into cement kiln, metallurgy chemical kiln and lime kiln according to different materials.
Rotary calcining kiln application:
Rotary calcining kiln is used for making of cement clinker and there are dry and wet methods to make cement. Metallurgy chemical kiln is used in metallurgy industry and ironworks for lean iron ore, chromium ore and ferronickel ore calcimine. Rotary kiln is used for calcimine of high aluminum vandal ochre in refractory material industry; For calcimine of calotte and aluminum hydroxide in aluminum manufacturer; For claiming of chrome sand ore and chrome powder ore in chemical plant.
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 kilnProduct 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, energysaving 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.
