Product Description

Energy-Efficient Dolomite Stone Magnesium Production Line

Product Introduction
The metallic magnesium production line is a masterfully designed rotary kiln, precisely tailored to meet the distinctive calcining characteristics of dolomite and the specific requirements of the Pidgeon method for magnesium smelting. It serves as the foundation of the dolomite calcining system. This cutting-edge products produced in the rotary kiln consistently exhibit stable and homogeneous quality, featuring extraordinary activity and minimal ignition loss. This guarantees full adherence to Pidgeon method standards for magnesium smelting, thereby enhancing the magnesium extraction rate and optimizing silicon utilization, while significantly reducing the production and consumption costs associated with metallic magnesium. It is the definitive equipment for dolomite calcination within the magnesium sector, setting the industry standard for excellence.
The comprehensive magnesiumsmelting process includes raw material storage, dolomite calcination, grinding, briquetting, reduction, and refining. Initially, the raw dolomite is precisely crushed into ideal sizes (20-40mm) by specialized crushers, then sintered in a rotary kiln and effectively cooled by an advanced cooler. It is further ground into fine powder through cutting-edge ball mill machinery and formed into balls using a high-performance ball press. Calcination occurs in a rotary or vertical kiln, transforming dolomite into calcined white. This is then meticulously blended with ferrosilicon and fluorite powders to create a perfect mixture, placed in a heat-resistant stainless steel reduction tank, and subjected to reduction in a furnace, reaching temperatures of 1200-1250°C with a vacuum of 1.33Pa. The process concludes with the extraction of crude magnesium, followed by flux refining, ingot casting, and detailed surface treatment to produce top-quality magnesium ingots.

Product Advantages
1) Leading-Edge Fuel Combustion Technology: Showcasing state-of-the-art energy-saving burners, our system automatically manages air distribution, thereby maximizing thermal efficiency in fuel consumption.
2) The rotary kiln is fitted with a sophisticated vertical preheater, which ingeniously utilizes the high-temperature flue gas generated during rotary kiln combustion, preheating materials within the preheater efficiently. This strategic approach enables materials to undergo partial decomposition within the preheater, which enhancesthe overall system output while further optimizing thermal efficiency for superior performance.
3) Leading the kiln is a high-efficiency vertical cooler that expertly captures the heat from the high-temperature whitened materials of the rotary kiln, preheating secondary air to an impressive 650°C. This sophisticated design significantly boosts thermal efficiency and delivers exceptional economic returns.
