Mineral Roasting Kiln
In the mineral roasting kiln, electrical motor will drive the gear wheel and then kiln body is driven by the impetus. There is a professional nozzle equipped at the kiln head. On one hand, the nozzle will inject the coal powder into the kiln.
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.
In order to lower the operation cost, the series of rotary kiln mix block with powder in calcining
The green ore measured by the electronic belt scale, belt conveyor, steady bunker, and air lock valves in the reservoir will be fed into rotary kiln end directly
The steady bunker is located only in kiln end in order to lower the cost
Put into the rotary kiln will be heated first; Moves oppositely to the hot air
Heat to reduction temperature in the heating area and then enters into the reduction area where the temperature of the central flame zone is kept at about 1,000 degree Celsius and the temperature of the steam zone is kept at about 700 degree Celsius
Then the ore is reacted with the reduction gas and become magnetic ore for dressing by magnetic separation
