Product Description

Metallurgical Dolomite Rotary Kiln Production Line of 100-600tpd

Product Introduction
The metallic magnesium production line is an ingeniously designed rotary kiln, meticulously crafted to meet the unique calcining characteristics of dolomite and the stringent process requirements of the renowned Pidgeon method for magnesium smelting. This kiln is the cornerstone of the dolomite calcining system, offering unmatched efficiency and precision. products produced by this advanced rotary kiln exhibit remarkable stability and consistent quality, featuring high reactivity and minimal loss on ignition, it impeccably fulfills the rigorous demands of the Pidgeon method for magnesium smelting. This design enhances the magnesium extraction rate and optimizes silicon utilization, substantially reducing production costs and magnesium consumption,. It stands as the essential equipment for dolomite calcination in the magnesium manufacturing industry.
The comprehensive process of magnesiumsmelting unfolds through a series of precise stages: commencing with raw material storage, followed by dolomite calcination, grinding, and briquetting, and culminating in reduction and refining. Initially, the raw dolomite is reduced to optimal 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 then uniformly blended 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 yield refined magnesium ingots.

Product Advantages
1) Fuel combustion equipment: Features cutting-edge energy-saving burners to automatically regulate air distribution, and optimize 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 innovative method allows the materials to initiate partial decomposition within the preheater,, thereby dramaticallyenhancing system performance and maximizing thermal efficiency.
3) A vertical cooler at the kiln's forefront efficiently harnesses 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 outstanding economic returns.
