Product Description

Reliable Metallurgical Steel Plant Dolomite Rotary Kiln Production Line

Product Introduction
The metallic magnesium production line is an intricately engineered rotary kiln, thoughtfully crafted to address the specific calcining nuances of dolomite and the demanding process conditions of the celebrated Pidgeon method for magnesium smelting. As the cornerstone of the dolomite calcining system, this kiln delivers unmatched efficiency and accuracy. products produced by this rotary kiln are distinguished by exceptional stability and consistent quality, featuring high activity and minimal ignition loss, seamlessly aligning with the stringent process specifications of the Pidgeon method for magnesium smelting. This approach not only optimizes the magnesium extraction rate and silicon usage but also markedly cuts down on production costs and consumption of metallic magnesium,. It is undeniably the ultimate equipment for dolomite calcination in the magnesium industry.
The entire magnesiumsmelting process unfolds through a series of carefully orchestrated stages: beginning with raw material storage and proceeding to dolomite calcination, grinding, and briquetting, followed by the reduction and refining phases. Initially, raw dolomite is crushed to optimal sizes (20-40mm) using a crusher, sintered in a rotary kiln, cooled through a cooler, and milled into a fine powder by a ball mill. This powder is then compacted into balls using a ball press. Next, the calcined dolomite is meticulously blended with ferrosilicon and fluorite powders to create a dough, which is then placed into heat-resistant stainless steel reduction tanks. Within a reduction furnace, temperatures soar to 1200-1250°C under a vacuum of 1.33Pa. Here, crude magnesium is skillfully extracted, refined further, cast into ingots, and subjected to surface treatment, culminating in premium-grade magnesium ingots.

Product Advantages
1) Fuel combustion equipment: Features state-of-the-art energy-saving burners that automatically adjust air distribution, and maximize thermal efficiency.
2) A vertical preheater at the rotary kiln's end expertly utilizes the high-temperature flue gas from the kiln's combustion to preheat materials,. Through this, the materials can initiate partial decomposition within the preheater, thereby boosting system output and elevating thermal efficiency.
3) A vertical cooler at the kiln's head maximizes the residual heat from the kiln's high-temperature whitened material to preheat the secondary air to an impressive 650°C, further enhancing thermal efficiency and delivering significant economic benefits.
