Product Description

Metallurgical Dolomite Rotary Kiln Production Line offering expansive capacities ranging from 100 to 600 tpd, designed for unparalleled performance.

Product Introduction
The metallic magnesium production line features an expertly crafted rotary kiln, meticulously engineered to address the unique calcining characteristics of dolomite and the stringent process demands of the esteemed Pidgeon method for magnesium smelting. This kiln acts as the centerpiece of the dolomite calcining system, delivering unmatched efficiency and precision. products produced by this cutting-edge rotary kiln exhibit remarkable stability and unwavering quality, featuring high reactivity and minimal loss on ignition, seamlessly aligning with the rigorous requirements of the Pidgeon method for magnesium smelting. This innovative design augments the magnesium extraction rate and optimizes silicon utilization, dramatically reducing production costs and metallic magnesium consumption,. It represents the essential equipment for dolomite calcination in the magnesium manufacturing domain.
The comprehensive magnesiumsmelting process unfolds through a well-coordinated series of stages: starting 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 elevated to 1200-1250°C under a vacuum of 1.33Pa, where crude magnesium is extracted, meticulously refined, cast into ingots, and subjected to surface treatment to produce refined magnesium ingots.

Product Advantages
1) Fuel combustion equipment: Employs state-of-the-art energy-saving burners to expertly manage air distribution, and amplify thermal efficiency.
2) A vertical preheater at the rotary kiln's conclusion optimally harnesses the high-temperature flue gas from the kiln's combustion to effectively preheat materials,. This trailblazing method enables the materials to begin partial decomposition within the preheater,, considerablyenhancing system output and elevating thermal efficiency.
3) A vertical cooler at the kiln's forefront expertly utilizes the heat from the kiln's high-temperature whitened material to preheat the secondary air to an impressive 650°C, further elevating thermal efficiency and ensuring remarkable economic returns.
