Product FEATURE

Pidgeon process is applied in the company’s Mg smelting technology in the process of magenesium productionb 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 started to use vertical pre-heater for the calcination of dolomite. This kind of new pre-heater saves fuel by 40% and increases the output by 30%.
We are leading manufacturer of complete equipment for magnesium production line. We have done many successful projects in both China and overseas countries. POSCO is world class iron and steel supplier in Korea. In the year 2011, we have signed an annual output of 100000 tons of magnesium metal project with the world iron and steel giant Korean Pohang iron. The whole set of equipment for their magnesium plant are supplied by us. We can provide plant design, equipment supply, consultation and technical service for dolomite & magnesite calcination.
Pidgeon process is applied in the company's Mg smelting technology. This kind of process is advanced and reliable technology.
- More than 50 years experience in magnesium industry.
- Design capacity of single production line: 5,000-25,000 tons per year.
- Professional Process Design Engineers, Equipment Engineers, Electrical Engineers.
- Leading supplier of magnesium production line, and over 90% market share.

PRODUCTION PROCESS

Qualified dolomite is transported into the rotary kiln for calcination. Then calcined dolomite is mixed with fluorite and ferrosilicon and pressed into briquette. After that,the briquette is put into retorts where there is vacuum, and then deoxidized into crystallized magnesium, which is called crude Mg. Crude Mg is smelted and refined to get pure Mg.

The complete production line is divided into several systems including raw material storage, dolomite calcination, grinding & briquetting, reduction and refining. We can provide one stop service for dolomite & magnesite calcination, such as plant design, equipment/spare parts manufacturing, free consultation and technical design etc.

Our Technical Advantages:

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 preheater 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. Environmental Protection: Two phases of dust collection including cyclone filter and bag filter, will control the dust emission below the limitation of the national standard. The exhaust gas is recycled and dust emission can be controlled under 50mg/m3. This kind of new pre-heater takes up more than 85% in the market share.

4. High Degree of Automation: PLC control system improve the working efficiency.
