The Magnesium Metal Production Line is a complete industrial solution designed to extract high-purity magnesium metal (Mg) from dolomite via thermal reduction, commonly using the Pidgeon process. Magnesium is widely used in the automotive, aerospace, electronics, chemical, and metallurgical industries due to its lightweight and high-strength properties.
We provide turnkey magnesium production lines, offering reliable equipment, automation systems, and technical support to ensure stable operation, high efficiency, and environmental compliance.
Dolomite Crusher & Screening System
Prepares raw dolomite into required size fractions.
Ball Mill & Mixing System
Blends dolomite powder with ferrosilicon as a reducing agent.
Pelletizing Machine
Forms pellets for better thermal reaction in reduction furnaces.
Rotary Kiln for Calcination
Calcines dolomite at ~1000°C to produce CaO·MgO (calcined dolomite).
Reduction Furnace (Pidgeon Process)
Under vacuum and high temperature (~1200°C), magnesium is reduced and vaporized.
Magnesium Condensation System
Vaporized Mg is cooled and collected as solid magnesium ingots.
Cooling & Ingot Casting Line
Forms standardized magnesium ingots, ready for packaging and sale.
High Magnesium Recovery Rate (Up to 90%)
Energy-Efficient Rotary Kiln with optimized heat utilization
CE and ISO Certified Equipment
Low Environmental Impact - Dust & emission control systems included

| Product Advantages |
High work efficiency: The cooler and kiln head cover adopt vertical design, which is small footprint, and has good sealing performance. |
| Large production capacity, high degree of mechanization, and simple maintenance operations. | |
| Advanced performance: high operating rate, increased output by 30%, reduced heat consumption by 40%, and good production efficiency. | |
| Advanced structure: In addition to the main transmission, the transmission system is also equipped with an auxiliary transmission device that can still rotate the kiln body and prevent the kiln body from bending when the main power supply is interrupt. |
