Product Description

Metallurgical Dolomite Rotary Kiln Production Line of 100-600tpd

Product Introduction
The metallic magnesium production line is a masterfully designed rotary kiln, ingeniously crafted to meet the distinct calcining nuances of dolomite and the high standards required for the prestigious Pidgeon method in magnesium smelting. This kiln is the cornerstone of the dolomite calcining system, offering unmatched efficiency and precision. products produced by this cutting-edge rotary kiln exhibit remarkable stability and consistent quality, featuring high reactivity and minimal loss on ignition, seamlessly fulfilling the rigorous demands of the Pidgeon method for magnesium smelting. This design boosts the magnesium extraction rate and optimizes silicon utilization, significantly reducing production costs and metallic magnesium usage,. It is the essential equipment for dolomite calcination in the magnesium production industry.
The entire magnesiumsmelting process unfolds through an array of precise stages: starting with raw material storage, followed by dolomite calcination, grinding, and briquetting, and culminating in reduction and refining. Initially, the raw dolomite is crushed into optimal dimensions (20-40mm) using a crusher, sintered in a rotary kiln, cooled in a cooler, and finely milled by a ball mill. This powder is then molded into balls using a ball press. The calcined dolomite is then evenly mixed with ferrosilicon and fluorite powders to create a cohesive mixture, placed into robust heat-resistant stainless steel reduction tanks. Within the reduction furnace, the temperature escalates to 1200-1250°C under a vacuum of 1.33Pa, where crude magnesium is extracted, meticulously 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 precisely control air distribution, and maximize 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 groundbreaking method allows the materials to begin partial decomposition within the preheater,, thus significantlyenhancing system output and improving thermal efficiency.
3) A vertical cooler at the kiln's forefront fully utilizes the heat from the kiln's high-temperature whitened material to preheat the secondary air to an impressive 650°C, further boosting thermal efficiency and ensuring stellar economic returns.
