The rotary kiln is a long tube that rotates on large bearings the kiln is lined with insulation and refractory materials raw slate is fed from the storage silos into patented preheaters that allow the rock to heat up at a moderate rate it then enters the upper end of the kiln where it slowly revolves and moves toward the burn zone.
Rotary kilns a rotary kiln is a type of furnace commonly used to heat solid materials in the form of a powder lump or other granular form rotary kilns are used for any number of purposes from heating soil to remove volatile contaminants to heating stones to remove moisture.
The 2base rotary kiln is a statically determined beam system where the support load is always known it is a shorter and wider kiln with a reduced slope to maintain the material retention time similar to a 3base kiln the larger diameter reduces the gas velocity and the dust recircula.
The first reaction zone of rotary kiln system is known as the preheating zone here the charge gets heated up to about 800 before entering the calcining zone bricks in this area are prone to chemical attack from gases containing alkali and sulphur thermal insulating property of the refractories in this area results in substantial fuel savings.
