Product Description

Metallurgical Dolomite Rotary Kiln Production Line of 100-600tpd

Product Introduction
The metallic magnesium production line is an expertly crafted masterpiece of engineering. This rotary kiln has been meticulously designed to address the distinctive calcining characteristics of dolomite, while meeting the stringent process requirements of the distinguished Pidgeon method for magnesium smelting. As the cornerstone of the dolomite calcining system, it offers unmatched efficiency and precision in processing. products produced by this cutting-edge rotary kiln are known for their exceptional stability and uniform quality, boasting high reactivity and minimal loss on ignition, ensuring it meets the rigorous requirements of the Pidgeon method for magnesium smelting with ease. This innovative design significantly enhances the magnesium extraction rate and optimizes silicon utilization, leading to substantial reductions in production costs and the consumption of metallic magnesium,. It stands as an indispensable piece of equipment for dolomite calcination, pivotal to the magnesium manufacturing sector's success.
The complete process of magnesiumsmelting unfolds through a series of meticulously orchestrated stages: beginning with raw material storage, proceeding to dolomite calcination, followed by grinding and briquetting, and culminating in reduction and refining. Initially, raw dolomite is reduced to optimal sizes (20-40mm) by a crusher, sintered in a rotary kiln, cooled in a cooler, and finely ground in a ball mill. This powder is then compressed into balls using a ball press. The calcined dolomite is uniformly blended with ferrosilicon and fluorite powders, forming a cohesive dough, which is placed into heat-resistant stainless steel reduction tanks. Inside the reduction furnace, temperatures soar 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 cutting-edge energy-saving burners that automatically regulate air distribution, and enhance thermal efficiency.
2) A vertical preheater, strategically situated at the rotary kiln's terminus, capitalizes on the high-temperature flue gas from the kiln's combustion to preheat materials,. This innovative approach allows the materials to initiate partial decomposition within the preheater,, thereby significantlyboosting system output and enhancing 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 impressive 650°C. This further amplifies thermal efficiency and ensures outstanding economic returns.
