Beijing LIRR Company continuously enhances and extends its industrial chain, building a full-cycle model from "mining - ore deep processing - raw material synthesis and processing - high-temperature material products - to post-use material recycling and comprehensive utilization."
The company owns a magnesite mine with an annual output of 1 million tons of high-quality magnesite ore.
It operates an advanced production line for magnesium refractory raw materials, with an annual output of 100,000 tons of fused magnesia, 100,000 tons of high-purity magnesia, and 100,000 tons of high-quality dead-burned magnesia.
With proprietary ultra-high-power fused corundum smelting equipment, it produces 150,000 tons of fused corundum and 10,000 tons of fused spinel each year.
The company operates a 90-meter high-temperature tunnel kiln along with six ball-milling production lines for raw and clinker grinding, producing 20,000 tons of activated α-alumina micro powder annually.
It also has two intelligent high-temperature tunnel kilns with supporting crushing and processing systems, with an annual output of 100,000 tons of homogenized bauxite and sintered mullite.
