Energy Saving Cement Kiln Applied in Cement Industry

A kiln is a thermally insulated chamber, a type of oven that produces temperatures sufficient to complete some process, such as hardening, drying, or chemical changes. Various industries use rotary kilns for pyroprocessing—to calcinate ores, to calcinate limestone to lime for cement, and to transform many other materials.

Function of Cement Kiln

The function of the kiln in the cement industry is to first convert CaCO3 into CaO and then react Silica, Aluminum Oxide, Ferric Oxide, and Calcium Oxide with the free lime to form clinker compounds: C3S, C2S, C3A, and C4AF. The cement kiln uses higher temperatures to form the clinker.

Cement kilns are 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.

Structure of Cement Kilns:

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.
