Product Description

Metallurgical Dolomite Rotary Kiln Production Line of 100-600tpd

Product Introduction
The metallic magnesium production line This expertly crafted rotary kiln is meticulously engineered to master the unique calcining characteristics of dolomite and the stringent process demands of the esteemed Pidgeon method for magnesium smelting. As the linchpin of the dolomite calcining system, it stands out by delivering unmatched efficiency and precision. products produced by this state-of-the-art rotary kiln exhibit remarkable stability and unwavering quality,, boasting high reactivity and minimal loss on ignition. It 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 stands as indispensable equipment for dolomite calcination within the magnesium manufacturing sector.
The complete process of magnesiumsmelting unfolds through a series of meticulously orchestrated stages: starting with raw material storage, advancing through dolomite calcination, grinding, and briquetting, and culminating in reduction and refining. Initially, raw dolomite is broken down to optimal sizes (20-40mm) using a crusher, sintered in a rotary kiln, cooled in a cooler, and then finely ground by a ball mill. This processed powder is 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, temperatures soar to 1200-1250°C under a precise vacuum of 1.33Pa, where crude magnesium is meticulously extracted, refined, cast into ingots, and subjected to surface treatment to yield pristine magnesium ingots.

Product Advantages
1) Fuel combustion equipment: Features cutting-edge energy-saving burners that automatically manage air distribution, and boost thermal efficiency.
2) A vertical preheater at the rotary kiln's terminus innovatively utilizes 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 significantlyenhancing system output and boosting 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, thereby further augmenting thermal efficiency and ensuring outstanding economic returns.
