Product Description

Metallurgical Dolomite Rotary Kiln Production Line of 100-600tpd

Product Introduction
The metallic magnesium production line is an expertly crafted rotary kiln, meticulously engineered to address the unique calcining characteristics of dolomite and meet the exacting process demands of the prestigious Pidgeon method for magnesium smelting. This kiln is the cornerstone of the dolomite calcining system, offering unmatched efficiency and precision. products produced by this state-of-the-art rotary kiln showcase exceptional stability and unwavering quality, boasting high reactivity and minimal loss on ignition, expertly fulfilling the rigorous requirements of the Pidgeon method for magnesium smelting. This advanced design boosts the magnesium extraction rate and enhances silicon utilization, significantly reducing production costs and diminishing the consumption of metallic magnesium,. It stands as the indispensable equipment for dolomite calcination within the magnesium manufacturing sector.
The complete process of magnesiumsmelting unfolds through a series of precisely orchestrated stages: starting with raw material storage, followed by dolomite calcination, grinding, and briquetting, and concluding with reduction and refining. Initially, the raw dolomite is broken down into optimal sizes (20-40mm) using a crusher, sintered in a rotary kiln, cooled in a cooler, and finely ground by a ball mill. This fine powder is then compressed into balls using a ball press. The calcined dolomite is uniformly mixed with ferrosilicon and fluorite powders to create 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 pristine magnesium ingots.

Product Advantages
1) Fuel combustion equipment: Integrates cutting-edge energy-saving burners to automatically fine-tune air distribution, and enhance thermal efficiency dramatically.
2) A vertical preheater at the rotary kiln's endpoint optimally 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 harnesses the heat from the kiln's high-temperature whitened material to preheat the secondary air to an impressive 650°C, further elevating thermal efficiency and ensuring remarkable economic returns.
