Cement rotary kiln is the main equipment used in cement clinker dry and wet production line; it is one of the lime kilns, belonging to the class of building materials equipment.
The cement kiln is mainly used for calcining cement clinker, including dry process production cement kiln and wet process production cement kiln.
Structure
The rotary kiln is composed by the cylinder, the supporting device with gear wheel, transmission device, movable kiln hood, kiln end sealing device and coal-injection duct device.
Kiln body of rotary kiln is parallel with horizontal with a certain slope; the kiln body is supported by supporting device, it controls the blocking device of kiln; in addition to the main drive, it is also equipped with the auxiliary drive system, which keeps the kiln rotating when main power is interrupted and prevents kiln bending and deformation; kiln hood and kiln end sealing uses state-of-the-art technology devices, ensuring the reliability of sealing.
Feature
Cement rotary kiln is characterized by sturdy construction, smooth operation, high-quality products; and it can provide users with advanced efficient shaft preheater and cyclone preheater.
Applications
Apart from the calcination of cement clinker, cement rotary kilns is also used to calcine clay, limestone and slag drying; in the production of refractory materials, rotary kiln could make it dimension stable, strength increased and re- process fashioned.
In addition, in the environmental aspects, adopting cement kilns to burn hazardous waste and garbage could makes waste minimization and harmless, and waste can be used as a fuel, saving pulverized coal and changing waste into resources.
