Product Description

Metallurgical Dolomite Rotary Kiln Production Line of 100-600tpd

Product Introduction
The metallic magnesium production line presents an expertly crafted rotary kiln, meticulously engineered to meet the distinct calcining characteristics of dolomite. This kiln, a cornerstone in dolomite processing, seamlessly addresses the stringent process demands of the renowned Pidgeon method for magnesium smelting, ensuring unparalleled efficiency and precision. products produced by this cutting-edge rotary kiln exemplify extraordinary stability and consistent quality, featuring high reactivity and minimal loss on ignition, it impeccably aligns with the demanding standards of the Pidgeon method for magnesium smelting. This innovative design not only improves magnesium extraction rates but also enhances silicon utilization, drastically reducing production costs and consumption of metallic magnesium,. It stands as the essential equipment for dolomite calcination within the magnesium manufacturing industry.
The comprehensive magnesiumsmelting process unfolds through a series of meticulously orchestrated stages: starting with raw material storage, progressing through dolomite calcination, grinding, and briquetting, and finally moving into reduction and refining. Initially, raw dolomite is processed into optimal sizes (20-40mm) using a crusher, sintered in a rotary kiln, cooled, and finely ground by a ball mill. This resultant powder is then compressed into balls with a ball press. The calcined dolomite is uniformly mixed with ferrosilicon and fluorite powders to create a cohesive dough, placed in heat-resistant stainless steel reduction tanks. In 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 to produce finished magnesium ingots.

Product Advantages
1) Fuel combustion equipment: Utilizes cutting-edge energy-saving burners to seamlessly automate air distribution, and maximize thermal efficiency.
2) A vertical preheater located at the rotary kiln's end optimally harnesses the high-temperature flue gas from kiln combustion to preheat materials,. This forward-thinking approach allows the materials to begin partial decomposition within the preheater,, thereby significantlyboosting system throughput and enhancing thermal efficiency.
3) A vertical cooler at the kiln's entrance fully capitalizes on the heat from the kiln's high-temperature whitened material to preheat secondary air to an impressive 650°C, further enhancing thermal efficiency and ensuring excellent economic benefits.
