Magnesium Production Line

Henan zhengzhou mining machinery co., ltd began to manufacture equipments for mg smelting industry from 1988, and focused on the technology upgrading and utilization. During 2003-2005, the company invented vertical pre-heater for the calcination of dolomite. This kind of new pre-heater saves fuel by 40% and increases the output by 30%. The exhaust gas is recycled and dust emission can be controlled under 50mgm3. This kind of new pre-heater takes up more than 85% in the market share. The company has got the patent of energy-saving rotary kiln, vertical pre-heater and vertical cooler.
Pidgeon process is applied in the company’s mg smelting technology. This kind of process is advanced and reliable technology.
Our advantage
1. Energy saving
the refractory lining of the rotary kiln consists of the outer insulation made of light refractory brick and inner compound refractory bricks, which will reduce the heat emission on the shell surface of the rotary kiln. The pre-heater at the end of the rotary kiln will recycle the heat to preheat the material and save fuel by 40% and increase the output by 30%.
2. Low consumption
the vertical cooler at the discharge end of rotary kiln recycles the heat of the calcined dolomite which is discharged from the rotary kiln, and will preheat the secondary air up to 600℃. The vertical cooler is integrated with kiln hood to prevent the waste caused by heat emission from the discharged calcined dolomite.
3. Envioronmental protection
two phases of dust collection including cyclone filter and bag filter, will control the dust emission below the limitation of the national standard.
4. High degree of automation
plc control system improve the working efficiency.
