Product Description

Metallurgical Dolomite Rotary Kiln Production Line of 100-600tpd

Product Introduction
The metallic magnesium production line This rotary kiln is a masterpiece of engineering, specifically tailored to meet the intricate calcining properties of dolomite. It perfectly accommodates the exacting requirements of the revered Pidgeon method for magnesium smelting. As the cornerstone of the dolomite calcining system, this kiln delivers unmatched efficiency and precision, setting a new standard in the industry. products crafted by this cutting-edge rotary kiln showcase remarkable stability and unwavering quality, featuring exceptional reactivity and minimal loss on ignition. It seamlessly aligns with the stringent demands of the Pidgeon method for magnesium smelting. This sophisticated design not only amplifies the magnesium extraction rate but also optimizes silicon utilization, dramatically reducing production costs and metallic magnesium consumption,. It is recognized as an essential apparatus for dolomite calcination within the magnesium manufacturing industry.
The complete magnesiumsmelting process unfolds through a sequence of well-orchestrated stages: commencing with raw material storage, proceeding with dolomite calcination, grinding, and briquetting, and culminating in reduction and refining. Initially, raw dolomite is crushed to optimal sizes (20-40mm) using a crusher, sintered in a rotary kiln, cooled in a cooler, and finely milled by a ball mill. This powder is then compacted into balls using a ball press. Calcined dolomite is then uniformly blended with ferrosilicon and fluorite powders to create a cohesive blend, placed into heat-resistant stainless steel reduction tanks. Within the reduction furnace, temperatures are elevated to 1200-1250°C under a vacuum of 1.33Pa, where crude magnesium is extracted, further refined, cast into ingots, and undergoes surface treatment to produce pristine magnesium ingots.

Product Advantages
1) Fuel combustion equipment: Features advanced energy-efficient burners that automatically regulate air distribution, and elevate thermal efficiency.
2) A vertical preheater located at the rotary kiln's terminus strategically harnesses the high-temperature flue gas from the kiln's combustion to preheat materials,. This groundbreaking methodology enables the materials to undergo partial decomposition within the preheater,, thereby significantlyuplifting system output and augmenting thermal efficiency.
3) A 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, reaching an impressive 650°C. This advancement further heightens thermal efficiency, ensuring outstanding economic returns.
