Product Description

Introducing the Energy-Efficient Dolomite Stone Magnesium Production Line!

Product Introduction
The metallic magnesium production line is an expertly engineered rotary kiln, meticulously crafted to align with the unique calcining attributes of dolomite and the precise requirements of the Pidgeon method for magnesium smelting. It stands as the cornerstone of the dolomite calcining system. This state-of-the-art products emerging from the rotary kiln exhibit consistently stable and homogenous quality, boasting remarkable activity and minimal ignition loss. This ensures full compliance with Pidgeon method standards for magnesium smelting, thus enhancing the magnesium extraction rate and optimizing silicon utilization, while substantially lowering the production and consumption costs associated with metal magnesium. It is the quintessential equipment for dolomite calcination within the magnesium sector, setting the benchmark for excellence.
The comprehensive magnesiumsmelting process spans raw material storage, dolomite calcination, grinding, briquetting, reduction, and refining. Initially, the raw dolomite is precision-crushed into optimal sizes (20-40mm) by specialized crushers, then sintered in a rotary kiln and cooled effectively by a sophisticated cooler. It is further pulverized into fine powder through advanced ball mill machinery and formed into balls using a high-performance ball press. The calcination occurs in a rotary or vertical kiln, transforming dolomite into calcined white. This is then meticulously combined with ferrosilicon and fluorite powders to create a perfect dough, placed in a heat-resistant stainless steel reduction tank, and subjected to reduction in a furnace, reaching temperatures of 1200-1250°C and a vacuum of 1.33Pa. The process culminates with the extraction of crude magnesium, followed by flux refining, ingot casting, and meticulous surface treatment to yield premium magnesium ingots.

Product Advantages
1) Pioneering Fuel Combustion Technology: Featuring cutting-edge energy-saving burners, our system automatically regulates air distribution, thereby maximizing the thermal efficiency of fuel usage.
2) The rotary kiln is equipped with an advanced vertical preheater, which expertly capitalizes on the high-temperature flue gas produced during rotary kiln combustion, efficiently preheating the materials within the preheater. This strategic move allows materials to undergo partial decomposition within the preheater, which escalatesthe overall system output while further honing thermal efficiency for optimal performance.
3) At the kiln's forefront lies a high-efficiency vertical cooler that brilliantly harnesses the heat from the high-temperature whitened materials of the rotary kiln, preheating secondary air to a remarkable 650°C. This sophisticated design markedly boosts thermal efficiency and delivers outstanding economic returns.
