Product Description

Metallurgical Dolomite Rotary Kiln Production Line of 100-600tpd

Product Introduction
The metallic magnesium production line Introducing our expertly crafted rotary kiln, meticulously engineered to cater to the unique calcining characteristics of dolomite and the demanding process requirements of the prestigious Pidgeon method for magnesium smelting. This kiln serves as the cornerstone of the dolomite calcining system, offering exceptional efficiency and precision. products produced by this state-of-the-art rotary kiln exhibit remarkable stability and consistent quality, featuring high reactivity and minimal loss on ignition, it impeccably fulfills the rigorous requirements of the Pidgeon method for magnesium smelting. This innovative design boosts the magnesium extraction rate and enhances silicon utilization, significantly reducing production costs and the consumption of metallic magnesium,. It stands as the essential equipment for dolomite calcination in the magnesium manufacturing sector.
The complete process of magnesiumsmelting is a carefully orchestrated sequence of stages: starting with raw material storage, progressing through dolomite calcination, grinding, and briquetting, and concluding with reduction and refining. Initially, the raw dolomite is reduced to 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 compacted into balls using a ball press. The calcined dolomite is uniformly blended with ferrosilicon and fluorite powders to form a homogeneous dough, which is then 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 produce finished magnesium ingots.

Product Advantages
1) Fuel combustion equipment: Features cutting-edge energy-saving burners for automatic air distribution management, and enhanced thermal efficiency.
2) A vertical preheater at the rotary kiln's terminus maximizes the use of high-temperature flue gas from the kiln's combustion to preheat materials,. This revolutionary method allows the materials to begin partial decomposition within the preheater,, thereby significantlyenhancing system output and improving thermal efficiency.
3) A vertical cooler at the kiln's forefront fully leverages the heat from the kiln's high-temperature whitened material to preheat the secondary air to an impressive 650°C, further boosting thermal efficiency and ensuring exceptional economic returns.
