Product Description

Metallurgical Dolomite Rotary Kiln Production Line of 100-600tpd

Product Introduction
The metallic magnesium production line is a masterfully designed rotary kiln, precisely crafted to cater to the specific calcining characteristics of dolomite and meet the exacting process requisites of the prestigious Pidgeon method for magnesium smelting. This kiln is the cornerstone of the dolomite calcining system, ensuring unmatched efficiency and accuracy. products produced by this cutting-edge rotary kiln guarantee outstanding stability and uniform quality, showcasing high reactivity and minimal loss on ignition, it impeccably satisfies the demanding standards of the Pidgeon method for magnesium smelting. This design elevates the magnesium extraction rate and optimizes silicon utilization, dramatically reducing production costs and metallic magnesium consumption,. It stands as the essential equipment for dolomite calcination in the magnesium production industry.
The comprehensive magnesiumsmelting process unfolds through a series of carefully orchestrated stages: starting with raw material storage, proceeding to dolomite calcination, grinding, briquetting, and culminating in reduction and refining. Initially, the raw dolomite is broken down into ideal 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 uniformly mixed with ferrosilicon and fluorite powders to form a cohesive dough, 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 subjected to surface treatment to produce premium magnesium ingots.

Product Advantages
1) Fuel combustion equipment: Features advanced energy-efficient burners to seamlessly manage air distribution, and maximize thermal efficiency.
2) A vertical preheater at the rotary kiln's terminus skillfully utilizes the high-temperature flue gas from the kiln's combustion to preheat materials,. This pioneering approach allows the materials to commence partial decomposition within the preheater,, thereby significantlyenhancing system output and maximizing thermal efficiency.
3) A vertical cooler at the kiln's forefront fully exploits the heat from the kiln's high-temperature whitened material to preheat the secondary air to an astounding 650°C, further boosting thermal efficiency and ensuring exceptional economic returns.
