Rotary Kiln

Rotary Kiln

Rotary kiln is a type of large hydrometallurgical equipment. As a kind of thermal equipment, it is widely used in the fields of cement, nonferrous metallurgy, ferrous metallurgy, refractory material, chemical materials, paper making, etc. Rotary calciner is also a pyroprocessing device used to raise materials to a high temperature in a continuous process.Rotary kiln is also applied to heat solids to the point where a required chemical reaction takes place. It is basically a rotating inclined cylinder. CORROCO Rotary calciner is the main equipment for dealing with low grade Zinc Oxide ore. that is,ZnO ore enrichment. This hydrometallurgical equipment has simple structure, less wearing parts and high efficiency, which makes it easy to operate.

Working Principle of Rotary Kiln:
The rotary calciner is a cylindrical vessel, inclined slightly to the horizontal, which is rotated slowly around its axis. The material to be processed is fed into the upper end of the cylinder. As the rotary kiln rotates, the materials gradually move down towards the lower end, and may undergo a certain amount of stirring and mixing. Hot gases pass along the rotary calciner sometimes in the same direction as the process material (co-current), but usually in the opposite direction (counter-current). The hot gases may be generated in an external furnace, or may be generated by a flame inside the rotary kiln. Such a flame is projected from a burner-pipe (or "firing pipe") which acts like a large burner. The fuel may be gas, oil or pulverized coal.
