A rotary kiln is a pyroprocessing device used to raise materials to a high temperature (calcination) in a continuous process. Materials produced using rotary kilns include: cement, Lime,Refractories, Metakaolin, Titanium dioxide, Alumina, Vermiculite, Iron ore pellets.
Application Range：Building material, metallurgy, chemical industry, electrical power and etc.
Applicable Materials：cement, Lime,Refractories, Metakaolin, Titanium dioxide, Alumina, Vermiculite, Iron ore pellets.
Low energy consumption
Our rotary kiln adopts reasonble running parameter; coal and electricity consumption can be 20% to 30% lower than common dryer.
High output capacity
Output capacity can be increased by more than 20%. Taida rotary kiln has been widely applied to mining and metallurgy industry.
With high automation level
The whole production line needs only one person to supervise. finished products can be directly packed and stored.
Service life can last for 8 to 10 years. with good maintenance, it can be used for longer time.
With less quick-wear parts.
Important parts adopt advanced thermal processing technology. Replace period can reach 5000 hours.
More environment friendly
Adopts multi-class dust collecting method, clean exhaust gas emission can totally meet national standard.
The kiln is a cylindrical vessel, inclined slightly to the horizontal, which is rotated slowly about its axis. The material to be processed is fed into the upper end of the cylinder. As the kiln rotates, material gradually moves down towards the lower end, and may undergo a certain amount of stirring and mixing. Hot gases pass along the kiln, 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 kiln. Such a flame is projected from a burner-pipe (or "firing pipe") which acts like a large bunsen burner. The fuel for this may be gas, oil, pulverized petroleum coke or pulverized coal.
