Product Description

Introducing our state-of-the-art Metallurgical Dolomite Rotary Kiln Production Line, capable of handling capacities from 100 to 600tpd, designed to meet all your calcining needs.

Product Introduction
The metallic magnesium production line is an expertly crafted masterpiece, a rotary kiln meticulously engineered to address the unique calcining characteristics of dolomite and the stringent demands of the esteemed Pidgeon method for magnesium smelting. This kiln stands as the cornerstone of the dolomite calcining system, delivering unparalleled efficiency and precision with every rotation. 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, improving the magnesium extraction rate and enhancing silicon utilization. This significantly lowers production costs and reduces metallic magnesium consumption,. It is the indispensable equipment for dolomite calcination in the magnesium manufacturing industry, truly a pinnacle of innovation.
The complete magnesiumsmelting process unfolds through a series of meticulous stages: beginning with raw material storage, followed by dolomite calcination, grinding, and briquetting, and culminating in reduction and refining. Initially, raw dolomite is broken into optimal sizes (20-40mm) using a crusher, sintered in a rotary kiln, cooled, and finely ground by a ball mill. This powder is compressed into balls using a ball press. The calcined dolomite is then uniformly mixed with ferrosilicon and fluorite powders to form a cohesive mixture, placed into heat-resistant stainless steel reduction tanks. Within the reduction furnace, the temperature is raised 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 high-quality finished magnesium ingots.

Product Advantages
1) Fuel combustion equipment: It features state-of-the-art energy-saving burners that automatically manage air distribution, and enhance thermal efficiency, maximizing performance.
2) A vertical preheater at the kiln's terminus optimally harnesses 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 significantlyboosting system output and enhancing thermal efficiency to new heights.
3) A vertical cooler at the kiln's forefront fully utilizes 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.
