Brief Introduction of Cement Rotary kiln

Cementis a kind of fine grinding material. After adding appropriate amount of water, it becomes plasticity slurry. The slurry can be hardened in the air and in water (must reach some certain strength after hardening), and it is kind of hydraulic cementing material that can firmly cemented sand and stone together and have other properties.

Cement Rotary kiln (Cement Kiln) is commonly used for the pyroprocessing stage of manufacture of Portland and other types of hydraulic cement, in which calcium carbonate reacts with silica-bearing minerals to form a mixture of calcium silicates. Cement kilns are the core equipment in the cement production process. The capacity usually defines the capacity of the cement plant. As the main energy-consuming and greenhouse-gas–emitting stage of cement manufacture, improvement of cement kiln efficiency has been the central concern of cement manufacturing technology.

Structure of Cement Rotary Kiln

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.
