Product Description

Metallurgical Dolomite Rotary Kiln Production Line of 100-600tpd

Product Introduction
The metallic magnesium production line is a masterfully designed rotary kiln, diligently engineered to meet the specific calcining needs of dolomite, fulfilling the demanding process requirements of the renowned Pidgeon method for magnesium smelting. This kiln is the cornerstone of the dolomite calcining system, offering unmatched efficiency and precision. products produced by this cutting-edge rotary kiln exhibit remarkable stability and uniform quality, featuring high reactivity and negligible loss on ignition, it seamlessly fulfills the stringent criteria of the Pidgeon method for magnesium smelting. This innovative design elevates the magnesium extraction rate and optimizes silicon utilization, significantly reducing production costs and metallic magnesium consumption,. It is the essential equipment for dolomite calcination in the magnesium production industry.
The complete magnesiumsmelting process unfolds through a series of precise stages: commencing with raw material storage, followed by dolomite calcination, grinding, and briquetting, and concluding with reduction and refining. Initially, raw dolomite is crushed into ideal sizes (20-40mm) with a crusher, sintered in a rotary kiln, cooled in a cooler, and finely milled by a ball mill. This powder is then compressed into balls using a ball press. The calcined dolomite is subsequently blended with ferrosilicon and fluorite powders to form a cohesive mixture, placed into heat-resistant stainless steel reduction tanks. In the reduction furnace, the temperature rises to 1200-1250°C under a vacuum of 1.33Pa, where crude magnesium is extracted, further refined, cast into ingots, and treated to produce finished magnesium ingots.

Product Advantages
1) Fuel combustion equipment: Features state-of-the-art energy-saving burners to automatically regulate air distribution, and optimize thermal efficiency.
2) A vertical preheater at the rotary kiln's end efficiently uses the high-temperature flue gas from the kiln's combustion to preheat materials,. This forward-thinking method allows the materials to undergo partial decomposition within the preheater,, thus markedlyenhancing system output and improving thermal efficiency.
3) A vertical cooler at the kiln's front fully utilizes the heat from the kiln's high-temperature whitened material to preheat the secondary air to an exceptional 650°C, further boosting thermal efficiency and ensuring remarkable economic returns.
