Product Description

Introducing our Metallurgical Dolomite Rotary Kiln Production Line, capable of processing between 100 to 600 tons per day (tpd), exemplifying our commitment to high efficiency and precision in dolomite calcination.

Product Introduction
The metallic magnesium production line is a masterfully designed rotary kiln, meticulously engineered to cater to the distinctive calcining properties of dolomite. It meets the stringent process demands of the prestigious Pidgeon method for magnesium smelting, establishing itself as the cornerstone of the dolomite calcining system, delivering unmatched efficiency and precision. products produced by this cutting-edge rotary kiln exhibit remarkable stability and consistently superior quality,, featuring high reactivity and minimal loss on ignition, flawlessly aligning with the rigorous specifications of the Pidgeon method for magnesium smelting. This innovative design optimizes the magnesium extraction rate while enhancing silicon utilization, significantly cutting down on production costs and reducing metallic magnesium consumption,. It is indispensable for dolomite calcination in the magnesium manufacturing sector, setting new benchmarks in operational excellence.
The comprehensive magnesiumsmelting process unfolds through a meticulously orchestrated sequence of stages: it commences with raw material storage, transitions through dolomite calcination, grinding, and briquetting, and culminates 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 finely ground by a ball mill. This powder is compressed into balls using a ball press. The calcined dolomite is then uniformly blended 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, facilitating the extraction of crude magnesium, which is then refined, cast into ingots, and given a surface treatment to produce finished magnesium ingots.

Product Advantages
1) Fuel combustion equipment: Features cutting-edge energy-saving burners that automatically manage air distribution, and significantly enhance thermal efficiency.
2) A vertical preheater at the rotary kiln's terminus exploits the high-temperature flue gas from the kiln's combustion to preheat materials,. This forward-thinking approach allows the materials to undergo partial decomposition within the preheater,, thereby substantiallyincreasing system output and bolstering thermal efficiency.
3) A vertical cooler at the kiln's forefront maximizes the heat from the kiln's high-temperature whitened material to preheat the secondary air to a remarkable 650°C, further enhancing thermal efficiency and ensuring excellent economic returns.
