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 while meeting the stringent process demands of the esteemed Pidgeon method for magnesium smelting. This state-of-the-art kiln is the cornerstone of the dolomite calcining system, providing unmatched efficiency and precision. products produced by this state-of-the-art rotary kiln demonstrate exceptional stability and consistent quality, boasting high reactivity and minimal loss on ignition, it flawlessly meets the rigorous requirements of the Pidgeon method for magnesium smelting. This innovative design improves the magnesium extraction rate and enhances silicon utilization, significantly reducing production costs and metallic magnesium consumption,. It stands as the indispensable equipment for dolomite calcination in the magnesium manufacturing sector.
The complete process of magnesiumsmelting unfolds through a series of meticulous stages: commencing with raw material storage, followed by precise dolomite calcination, efficient grinding, and briquetting, culminating in reduction and refining. Initially, the raw dolomite is meticulously 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 powder is then expertly compressed into balls using a ball press. The calcined dolomite is uniformly mixed with ferrosilicon and fluorite powders to form a cohesive dough, which is strategically 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: Incorporates cutting-edge energy-saving burners to automatically regulate air distribution, and enhance thermal efficiency.
2) A vertical preheater at the rotary kiln's terminus optimally utilizes the high-temperature flue gas from the kiln's combustion to preheat materials,. This groundbreaking 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, further augmenting thermal efficiency and ensuring outstanding economic returns.
