Product Description

Our Metallurgical Dolomite Rotary Kiln Production Line, with a capacity ranging from 100 to 600 tpd, is a hallmark of precision engineering that delivers exceptional performance in dolomite processing.

Product Introduction
The production line of metallic magnesium is more than just an assembly of components; it is a testament to advanced engineering, designed to cater to the intricate calcining needs of dolomite. Our expertly crafted rotary kiln is meticulously engineered to address the unique calcining characteristics of dolomite and the stringent process demands of the esteemed Pidgeon method for magnesium smelting. Serving as the linchpin of the dolomite calcining system, it delivers unparalleled efficiency and precision, ensuring seamless operations and optimal results. The products emanating from this state-of-the-art rotary kiln demonstrate exceptional stability and consistent quality that exceeds industry standards,, with high reactivity and minimal loss on ignition. This kiln flawlessly meets the rigorous requirements of the Pidgeon method for magnesium smelting. It significantly enhances magnesium extraction rates and silicon utilization, dramatically lowering production costs and metallic magnesium consumption. It stands as the indispensable equipment for dolomite calcination in the magnesium manufacturing sector, reinforcing its critical role in efficient production processes.
The complete process of magnesiumsmelting unfolds through a series of meticulous stages: beginning with raw material storage, followed by dolomite calcination, grinding, and briquetting, culminating in reduction and refining. Initially, the raw dolomite is broken down 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 then uniformly mixed 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 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 finished magnesium ingots, achieving a seamless and efficient transition from raw material to final product.

Product Advantages
1) Fuel combustion equipment: Our system integrates cutting-edge energy-saving burners that automatically manage air distribution, and significantly enhance thermal efficiency.
2) The vertical preheater at the rotary kiln's terminus optimally utilizes the high-temperature flue gas from the kiln's combustion to preheat materials,an innovative approach that allows the materials to initiate partial decomposition within the preheater,, thereby significantlyboosting system output and enhancing thermal efficiency, ensuring a highly productive and energy-efficient operation.
3) The 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, further augmenting thermal efficiency and ensuring outstanding economic returns.
