Mercury ore rotary kiln calcination
The mercury ore rotary kiln is widely used for calcining ore in the chemical industry, metallurgy, building materials and other industries due to its excellent features and wide application range. Calcination is the important process of mercury ore preparation.
Low temperature decomposition and calcination of mercury ore utilizes the property that at low temperatures, the mercury ore has nephrectomy reaction activity, and converting the mercury ore into volatile mercury, which evaporates and escapes from the furnace, while other minerals remain in the kiln. During this process, there are also some toxic and harmful gases produced, so the environment of the calcining process must be kept clean.
The mercury ore rotary kiln needs to be characterized with advanced technology, good quality and high thermal efficiency. The heating furnace of the mercury ore rotary kiln is equipped with advanced thermocouple temperature control system to detect the temperature of the kiln body, to ensure the calcining temperature of the material is uniform. The rotary kiln body is made of alloy steel plate with good heat and corrosion resistance and long service life.
The equipment used in the calcination of mercury ore is usually three-return structure and multi-stage preheating, which can greatly improve the thermal efficiency. The rotary kiln burner is designed with two layers of combustion, which can make full use of the heat, improve the combustion efficiency and reduce the fuel consumption. The air distribution device adopts frequency conversion regulating motor control, and the secondary air can be adjusted stepwise.
The mercury ore rotary kiln is reliable in operation and high in output, and the entire calcination process is automatically operated. The quality of the calcined ores is stable, the combustion rate is high, and the thermal energy is well utilized. Therefore, it has become the major equipment for calcining mine ore in the modern ore industry.
