The metallic magnesium production line is a specific rotary kiln developed based on the calcining characteristics of dolomite and the process requirements of the Pidgeon method for magnesium smelting. It is the key equipment of the dolomite calcining system. The products produced by the rotary kiln has stable and uniform quality, high activity and low ignition loss, fully meets the process requirements of Pidgeon method for magnesium smelting, making the magnesium extraction rate and silicon utilization rate relatively high, reducing the production and consumption of metal magnesium. It is an ideal equipment for calcining dolomite in the magnesium industry.
The process of magnesium smelting includes raw material storage, dolomite calcination, grinding and briquetting, reduction and refining. The raw material (dolomite) is crushed into qualified materials (20-40mm) by the crusher, sintered in a rotary kiln, cooled by a cooler, ground into powder by a ball mill, and pressed into balls by a ball press. The dolomite is in the rotary kiln or vertical kiln Calcined into calcined white, crushed and evenly mixed with ferrosilicon powder and fluorite powder to form a dough, put into a heat-resistant stainless steel reduction tank, placed in a reduction furnace, reduced to 1200-1250°C and a vacuum of 1.33Pa. Take crude magnesium and undergo flux refining, ingot casting and surface treatment to obtain finished magnesium ingots.

| Product Advantages | Fuel combustion equipment: Use energy-saving burners to automatically control the air distribution volume and improve the thermal efficiency of the fuel. |
| There is a vertical preheater at the end of the rotary kiln, which makes full use of the high-temperature flue gas generated by the combustion of the rotary kiln to preheat the materials in the preheater. Through this, the materials can partially decompose in the preheater, increase the system output and improve thermal efficiency. | |
| There is a vertical cooler at the head of the rotary kiln, which makes full use of the heat contained in the high-temperature whitened material of the rotary kiln to preheat the secondary air to 650°C, thereby improving the thermal efficiency and achieving good economic benefits. |
