Product Description

Metallurgical Dolomite Rotary Kiln Production Line of 100-600tpd

Product Introduction
The metallic magnesium production line Our expertly crafted rotary kiln is meticulously engineered to meet the distinct calcining requirements of dolomite, addressing the stringent process demands of the renowned Pidgeon method for magnesium smelting. This kiln serves as the pivotal element of the dolomite calcining system, delivering unmatched efficiency and precision. products produced by our cutting-edge rotary kiln exhibit exceptional stability and consistent quality, boasting high reactivity and minimal loss on ignition, flawlessly meeting the rigorous standards of the Pidgeon method for magnesium smelting. This innovative design enhances magnesium extraction rates and optimizes silicon utilization, significantly reducing production costs and metallic magnesium consumption,. It is the essential equipment for dolomite calcination in the magnesium manufacturing industry.
The complete process of magnesiumsmelting is executed through a series of meticulously engineered stages: commencing with raw material storage, followed by dolomite calcination, grinding, and briquetting, leading to reduction and refining. Initially, raw dolomite is meticulously broken down into ideal sizes (20-40mm) using advanced crushers, sintered in a state-of-the-art rotary kiln, cooled in an efficient cooler, and finely ground in a high-performance ball mill. This powder is then expertly compressed into balls using a specialized ball press. The calcined dolomite is homogeneously mixed with ferrosilicon and fluorite powders to form a cohesive dough, placed into heat-resistant stainless steel reduction tanks. Within the reduction furnace, the temperature is precisely raised to 1200-1250°C under a vacuum of 1.33Pa, where crude magnesium is expertly extracted, refined, cast into ingots, and subjected to surface treatment to yield premium finished magnesium ingots.

Product Advantages
1) Fuel combustion equipment: Features cutting-edge energy-saving burners designed to automatically optimize air distribution, and enhance thermal efficiency.
2) A vertical preheater at the end of the rotary kiln is ingeniously designed to utilize high-temperature flue gas from the kiln's combustion to preheat materials,. This innovative system allows the materials to begin partial decomposition within the preheater,, significantlyboosting system output and enhancing thermal efficiency.
3) A vertical cooler at the kiln's forefront expertly harnesses the heat from the kiln's high-temperature material to preheat secondary air to an impressive 650°C, further enhancing thermal efficiency and ensuring outstanding economic returns.
