The electric heating rotary kiln, also known as electric rotary kiln, is rotary kiln equipment that uses resistance material as an electric heating element for heating. Electric heating is generally used in indirect heating rotary kilns. The electric rotary kiln is important equipment for roasting metal oxides or chemical products in the non-ferrous metallurgy and chemical industries.

The heating elements of the electric rotary kiln use nickel-chromium alloy (1Cr18Ni9Ti or Cr25Ni20Si2) or iron-chromium aluminum alloy (0Cr13A14 or 0Cr25A15) to make spiral heating elements, which are generally installed on both sides and bottom of the electric heating rotary kiln. There are four groups of heating elements in the electric heating rotary kiln, that is, four heating temperature control zones, and the temperature of each zone can be set separately. Its rated heating power can reach 300 kW, which can meet the heating requirements of electric heating rotary kiln, and the power will be reduced after the stable operation of the equipment. The advantages of the electric rotary kiln heating device are that the heating is uniform and the thermal efficiency is high.
The advantages in the production process of the electric rotary kiln are also obvious.
High thermal efficiency, no smoke, no ash, and slag to take away obvious heat.
It is easy to automatically control the conditions, the kiln temperature control accuracy is high, and it is suitable for the narrow pre-firing temperature process.
In addition, the electric rotary kiln does not need to build fuel storage and transportation station, which simplifies the work of fuel procurement, transportation, and safety management. During the production process, the corrosion of the kiln body due to SO2 gas and environmental pollution problems can be avoided. Therefore, the electric heating rotary kiln is more economical than the gas fuel rotary kiln and the oil fuel rotary kiln.
