Product Description

Metallurgical Dolomite Rotary Kiln Production Line of 100-600tpd

Product Introduction
The metallic magnesium production line is an ingeniously designed rotary kiln, crafted with precision to meet the distinctive calcining needs of dolomite and the demanding criteria of the renowned Pidgeon method for magnesium smelting. This kiln is the cornerstone of the dolomite calcining system, offering unmatched efficiency and precision in its operations. products produced by this cutting-edge rotary kiln exhibit remarkable stability and uniform quality, boasting excellent reactivity and minimal loss on ignition, it seamlessly fulfills the exacting standards of the Pidgeon method for magnesium smelting. This innovative design elevates the magnesium extraction rate and optimizes silicon utilization, significantly reducing production costs and the consumption of metallic magnesium,. It represents the essential equipment for dolomite calcination within the magnesium production industry.
The comprehensive magnesiumsmelting process unfolds through a series of carefully orchestrated stages: starting with raw material storage, followed by the calcination of dolomite, grinding, and briquetting, and culminating in reduction and refining. Initially, raw dolomite is crushed to ideal 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 compacted into balls using a ball press. The calcined dolomite is uniformly mixed with ferrosilicon and fluorite powders to create a cohesive mixture, placed in heat-resistant stainless steel reduction tanks. Within the reduction furnace, the temperature rises 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 produce completed magnesium ingots.

Product Advantages
1) Fuel combustion equipment: Features advanced energy-efficient burners to automatically regulate air distribution, and boost thermal efficiency.
2) A vertical preheater at the rotary kiln's end optimally utilizes the high-temperature flue gas from the kiln's combustion to preheat materials,. This groundbreaking method allows the materials to begin partial decomposition within the preheater,, thereby dramaticallyincreasing system output and improving 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 to an impressive 650°C, thus further boosting thermal efficiency and ensuring exceptional economic returns.
