Product Description

Metallurgical Dolomite Rotary Kiln Production Line of 100-600tpd

Product Introduction
The metallic magnesium production line is a masterfully designed rotary kiln system, thoughtfully engineered to cater to the distinct calcining properties of dolomite and meet the exacting process standards of the renowned Pidgeon method for magnesium smelting. This kiln is the cornerstone of the dolomite calcining system, ensuring unmatched efficiency and precision in operation. products produced by this cutting-edge rotary kiln exhibit remarkable stability and unwavering quality,, boasting impressive reactivity, and minimal loss on ignition. It flawlessly satisfies the stringent demands of the Pidgeon method for magnesium smelting, enhancing the magnesium extraction rate and amplifying silicon utilization, all while substantially reducing production costs and metallic magnesium consumption,. It stands as the essential equipment for dolomite calcination within the magnesium manufacturing industry.
The comprehensive process of magnesiumsmelting is meticulously orchestrated 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, the raw dolomite is crushed into optimal sizes (20-40mm) using a crusher, sintered in a rotary kiln, cooled in a cooler, and finely ground by a ball mill. This powder is then compressed into balls using a ball press. The calcined dolomite is meticulously combined with ferrosilicon and fluorite powders to form a cohesive dough, which is placed into heat-resistant stainless steel reduction tanks. Within the reduction furnace, the temperature is elevated to 1200-1250°C under a vacuum of 1.33Pa, where crude magnesium is extracted, further refined, cast into ingots, and treated on the surface to produce finished magnesium ingots.

Product Advantages
1) Fuel combustion equipment: Features advanced energy-saving burners that automatically 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 the kiln's combustion to preheat materials,. This pioneering approach allows the materials to undergo partial decomposition within the preheater,, thereby significantlyboosting system output and enhancing 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 a remarkable 650°C, further advancing thermal efficiency and ensuring exceptional economic returns.
