Product Description

Metallurgical Dolomite Rotary Kiln Production Line of 100-600tpd

Product Introduction
The metallic magnesium production line is a masterful creation, an expertly crafted rotary kiln meticulously engineered to tackle the unique calcining characteristics of dolomite. It addresses the stringent process demands of the esteemed Pidgeon method for magnesium smelting. As the linchpin of the dolomite calcining system, it delivers unparalleled efficiency and precision, making it a cornerstone in advanced dolomite processing. products produced by this state-of-the-art rotary kiln exemplify exceptional stability and consistent quality,, boasting high reactivity, and minimal loss on ignition. This system flawlessly meets the rigorous requirements of the Pidgeon method for magnesium smelting, enhancing the magnesium extraction rate and boosting silicon utilization. It significantly reduces production costs and metallic magnesium consumption,. It remains the indispensable equipment for dolomite calcination within the magnesium manufacturing sector.
The complete process of magnesiumsmelting unfolds through a meticulously orchestrated series of stages: starting with raw material storage, followed by dolomite calcination, grinding, and briquetting, and culminating in reduction and refining. Initially, raw dolomite is expertly 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. The resulting powder is then compressed into balls using a ball press. The calcined dolomite is uniformly mixed 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 to extract crude magnesium, which is further refined, cast into ingots, and undergoes surface treatment to yield finished magnesium ingots.

Product Advantages
1) Fuel combustion equipment: This system incorporates cutting-edge energy-saving burners that automatically manage air distribution, and enhance thermal efficiency, offering remarkable performance.
2) At the rotary kiln's terminus, a vertical preheater optimally exploits the high-temperature flue gas from the kiln's combustion to preheat materials. This innovative method enables the materials to begin partial decomposition within the preheater,, thereby significantlyboosting system output and elevating thermal efficiency to new heights.
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 improving thermal efficiency and ensuring outstanding economic returns.
