Product Description

Metallurgical Dolomite Rotary Kiln Production Line of 100-600tpd

Product Introduction
The metallic magnesium production line This expertly crafted rotary kiln is meticulously designed to conquer the unique calcining demands of dolomite, tailored for the esteemed Pidgeon method in magnesium smelting. As the centerpiece of the dolomite calcining system, it stands out with unmatched efficiency and precision. products produced by this cutting-edge rotary kiln display remarkable stability and unwavering quality, featuring exceptional reactivity and negligible loss on ignition. It seamlessly fulfills the stringent criteria of the Pidgeon method for magnesium smelting, boosting magnesium extraction rates and optimizing silicon usage. This results in substantial reductions in production costs and metallic magnesium consumption,. It is essential equipment for dolomite calcination in the magnesium manufacturing sector.
The comprehensive magnesiumsmelting process unfolds through a series of precise stages: beginning with the storage of raw materials, moving to dolomite calcination, grinding, and briquetting, and concluding with reduction and refining. Initially, raw dolomite is crushed into ideal sizes (20-40mm) by a crusher, sintered in a rotary kiln, cooled, and finely ground by a ball mill. This powder is then pressed into balls via a ball press. The calcined dolomite is intricately mixed with ferrosilicon and fluorite powders, forming a cohesive dough placed into heat-resistant reduction tanks. Inside the reduction furnace, temperatures rise to 1200-1250°C under a vacuum of 1.33Pa, where crude magnesium is extracted, refined, cast into ingots, and treated to produce finished magnesium ingots.

Product Advantages
1) Fuel combustion equipment: Features modern energy-saving burners that autonomously regulate air distribution, and enhance thermal efficiency.
2) A vertical preheater at the rotary kiln's end maximizes the use of high-temperature flue gas from kiln combustion to preheat materials,. This pioneering approach allows the materials to begin partial decomposition in the preheater,, dramaticallyincreasing system output and enhancing thermal efficiency.
3) A vertical cooler at the kiln's forefront fully harnesses the heat from the kiln's high-temperature whitened material to preheat the secondary air to an impressive 650°C, further boosting thermal efficiency and ensuring outstanding economic returns.
