Introduction of cement rotary kiln
Cement rotary kiln, which is mainly used for calcinating cement clinker, is the main equipment of the new dry type cement production line. This equipment is mainly composed of cylinder, supporting device, supporting device with catch wheel, transmission device, lubrication device, mobile kiln head and sealing device at the end of the kiln.
Working principle cement rotary kiln
Cement raw material is fed into the upper end of the kiln. As the kiln is rotated, the material moves slowly down the kiln through a calcining zone and then a clinkering zone, and is thereafter discharged through the discharge end of the kiln into a cooler.
Fuel is injected into the kiln from its lower end. As the fuel is burned in the kiln chamber, a large amount of heat is produced to sinter the limestone and clay. As hot air keeps rising along the kiln chamber, it ends up being emitted to the atmosphere via the air chimney.
