Product Description

Advanced Metallurgical Dolomite Rotary Kiln Production Line with a Capacity of 100-600tpd

Product Overview
The Pivotal Role of Metallic Magnesium Revolutionary Production Line This exceptionally designed rotary kiln is an engineering marvel, tailored to perfectly meet the distinct calcining needs of dolomite and the demanding specifications of the renowned Pidgeon method in magnesium smelting. As the central component of the dolomite calcining system, this kiln delivers unmatched efficiency and precision. Innovative Products The products born out of this cutting-edge rotary kiln manifest remarkable stability and unwavering quality consistency, featuring extraordinary reactivity and negligible loss on ignition. It seamlessly satisfies the stringent criteria of the Pidgeon method for magnesium smelting, optimizing the magnesium extraction rate and enhancing silicon utilization, which significantly reduces production expenses and metallic magnesium consumption,. It is the quintessential equipment for dolomite calcination in the magnesium production industry.
The comprehensive magnesium smelting processfollows a meticulously orchestrated sequence: starting with raw material storage, advancing to dolomite calcination, grinding, and briquetting, and concluding with reduction and refining. Initially, raw dolomite is crushed to optimal dimensions (20-40mm) with a crusher, sintered in a rotary kiln, cooled efficiently in a cooler, and finely pulverized by a ball mill. This powder is subsequently compacted into balls using a ball press. The calcined dolomite is then thoroughly blended with ferrosilicon and fluorite powders to create a cohesive mixture, which is placed into heat-resistant stainless steel reduction containers. Within the reduction furnace, the temperature escalates to 1200-1250°C under a vacuum of 1.33Pa, where crude magnesium is extracted, further purified, cast into ingots, and subjected to surface treatment to produce pristine magnesium ingots.

Distinctive Product Advantages
1) Fuel combustion apparatus: Features advanced energy-saving burners that automatically regulate air distribution, and enhance thermal efficiency.
2) The vertical preheater at the rotary kiln's terminal expertly captures the high-temperature flue gas from the kiln's combustion to preheat materials,. This innovative strategy enables the materials to initiate partial decomposition within the preheater,, thereby greatlyamplifying system output and promoting thermal efficiency.
3) The vertical cooler at the kiln's forefront fully capitalizes on the heat from the kiln's high-temperature, whitened material to preheat the secondary air up to an impressive 650°C, further enhancing thermal efficiency and securing remarkable economic returns.
