Product Description Metallurgical Dolomite Rotary Kiln Production Line with a capacity range of 100-600tpd. A marvel of engineering designed to elevate production standards and efficiency. Product IntroductionThe metallic magnesium production line is an expertly designed rotary kiln, precisely engineered to cater to the unique calcining properties of dolomite, conforming to the demanding process requirements of the renowned Pidgeon method for magnesium smelting. As the cornerstone of the dolomite calcining system, this kiln ensures unmatched efficiency and accuracy. products produced by this cutting-edge rotary kiln exhibit remarkable stability and consistent quality, boasting high reactivity and minimal loss on ignition. It perfectly aligns with the rigorous standards of the Pidgeon method for magnesium smelting, enhancing magnesium extraction rates and optimizing silicon utilization, thereby significantly reducing production costs and the consumption of metallic magnesium,. It is indispensable equipment for dolomite calcination in the magnesium manufacturing industry.The comprehensive magnesiumsmelting process unfolds through a series of precise stages: starting with raw material storage, progressing through dolomite calcination, grinding, and briquetting, and culminating in reduction and refining. Initially, raw dolomite is crushed into optimal sizes (20-40mm) via a crusher, sintered in a rotary kiln, cooled using a cooler, and finely ground by a ball mill. This powder is then compressed into balls with a ball press. The calcined dolomite is uniformly mixed with ferrosilicon and fluorite powders to form a cohesive mixture, placed into heat-resistant stainless steel reduction tanks. In the reduction furnace, temperatures rise to 1200-1250°C under a vacuum of 1.33Pa, where crude magnesium is extracted, then refined, cast into ingots, and finally subjected to surface treatment, achieving finished magnesium ingots.Product Advantages1) Fuel combustion equipment: Features advanced energy-saving burners with automatic air distribution control, and improved thermal efficiency.2) A vertical preheater at the end of the rotary kiln effectively utilizes the high-temperature flue gas from the kiln's combustion to preheat materials,. This innovative technique permits the materials to begin partial decomposition within the preheater,, thus significantlyenhancing system output and raising thermal efficiency.3) A vertical cooler at the kiln's forefront fully capitalizes on the heat from the kiln's high-temperature whitened material to preheat the secondary air to an impressive 650°C, improving thermal efficiency and ensuring superior economic returns.Main Technical SpecificationsDimension/mSpeed(r/min)Slope/%Capacity(t/h)ReducerMotor ModelMotor Powerφ1.6×32m0.58-2.8542ZQ75-50YCT250-4A18.5φ1.6/1.9×36m0.53-1.5942.5-3ZQ110-7YCTZ50-4B22φ1.9×39m0.53-1.5943-3.4ZQ125-7YCT315-4A37φ2.2×45m0.214-1.643.54-5Main: ZS125-5YCT315-4B45Auxiliary: ZQ40-40Y112M-44φ2.5×50m0.62-1.53.55-6Main: ZS165-5YCT355-4A55Auxiliary: ZS50-1Y160M-67.5φ2.5×55m0.62-1.53.55-6Main: ZS165-5YCT355-4A55Auxiliary: ZS50-1Y160M-67.5φ2.8×55m0.62-1.53.56-7Main: ZS165-5YCT355-4B75Auxiliary: ZS50-1Y160L-611φ3.0×60m0.5-1.53.57-9Main: ZS165-3ZSN-280-11B125Auxiliary: ZS50-1Y160L-611φ3.2×64m0.4-1.53.58-10Main: ZS130-16ZSN-280-11B190Auxiliary: Zl50-1Y180L-422φ3.5×70m0.4-1.53.512-14Main: ZSY500-40ZSN-315-082280Auxiliary: Zl50-14Y180L-422φ4.0×80m0.4-1.53.516-20Main: ZLY630-35.5ZSN-315-12355Auxiliary: ZSY280-35.5Y200L-430About UsShandong Bullis Metallurgical Engineering Co.,Ltd.Shandong Bullis Metallurgical Engineering Co., Ltd. proudly operates as a vital subsidiary of the distinguished Heze Shuanglong Metallurgical Machinery Group.
