Product Description

Introducing the Metallurgical Dolomite Rotary Kiln Production Line, masterfully designed to deliver outputs ranging from 100 to 600 tons per day!

Product Introduction
Within the world of metallic magnesium production, our cutting-edge production line is a marvel of modern engineering. This expertly crafted rotary kiln is meticulously designed to address the unique calcining characteristics of dolomite and meet the stringent process demands of the renowned Pidgeon method for magnesium smelting. It serves as the essential linchpin of the dolomite calcining system, providing unparalleled efficiency and precision that exceeds industry standards. The products that emerge from this state-of-the-art rotary kiln are nothing short of exceptional, demonstrating remarkable stability and consistent quality., These products boast high reactivity, and minimal loss on ignition. Our ingenious design flawlessly meets the rigorous requirements of the Pidgeon method for magnesium smelting, enhancing the magnesium extraction rate and optimizing silicon utilization. This significantly lowers production costs and reduces metallic magnesium consumption,. It is the indispensable equipment for any dolomite calcination process within the magnesium manufacturing sector, a true industry cornerstone.
The complete magnesium smelting process unfolds through a series of meticulously orchestrated stages:Beginning with raw material storage, followed by dolomite calcination, grinding, and briquetting, it culminates in reduction and refining. First, raw dolomite is broken 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 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. In the reduction furnace, the temperature rises 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: Our system incorporates state-of-the-art energy-saving burners that automatically manage air distribution, and enhance thermal efficiency with precision.
2) At the terminus of the rotary kiln, a vertical preheater optimally utilizes the high-temperature flue gas from the kiln's combustion to preheat materials,. This innovative approach allows materials to initiate partial decomposition within the preheater,, thereby significantlyboosting system output and enhancing thermal efficiency to new heights.
3) At the forefront of innovation, a vertical cooler at the kiln's entry fully exploits the heat from the kiln's high-temperature whitened material to preheat secondary air to an impressive 650°C, thus magnifying thermal efficiency and ensuring outstanding economic returns.
