Product Description

Metallurgical Dolomite Rotary Kiln Production Line of 100-600tpd

Product Introduction
The metallic magnesium production line Introducing a masterfully engineered rotary kiln, specifically crafted to meet the unique calcining requirements of dolomite. This exceptional equipment is designed to comply with the exacting standards of the Pidgeon method for magnesium smelting. The kiln is the pivotal element of the dolomite calcining system, offering unmatched efficiency and precision. products produced by this cutting-edge rotary kiln exhibit remarkable consistency and stability, featuring high reactivity and negligible loss on ignition, it precisely aligns with the stringent requirements of the Pidgeon method for magnesium smelting. This innovative design optimizes magnesium extraction rates and augments silicon utilization, substantially reducing production costs and decreasing metallic magnesium consumption,. It is the essential equipment for dolomite calcination in the magnesium production industry.
The comprehensive magnesiumsmelting process unfolds meticulously through several stages: starting with raw material storage, advancing through dolomite calcination, grinding, and briquetting, and culminating in reduction and refining. Initially, raw dolomite is crushed into ideal sizes (20-40mm) using a crusher, then sintered in a rotary kiln, followed by cooling in a cooler, and finely ground by a ball mill. The resulting powder is then compressed into balls via a ball press. The calcined dolomite is thoroughly mixed with ferrosilicon and fluorite powders to form a cohesive mixture, placed in heat-resistant stainless steel reduction tanks. Within 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 subjected to surface treatment to produce finished magnesium ingots.

Product Advantages
1) Fuel combustion equipment: Features advanced energy-saving burners that automatically regulate air distribution, and maximize thermal efficiency.
2) A vertical preheater at the rotary kiln's end efficiently utilizes the high-temperature flue gas from the kiln's combustion to preheat materials,. This revolutionary method enables the materials to begin partial decomposition within the preheater,, thereby dramaticallyincreasing system output and maximizing 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 the secondary air up to an impressive 650°C, further boosting thermal efficiency and delivering remarkable economic gains.
