Product Description

Introducing the Metallurgical Dolomite Rotary Kiln Production Line, capable of processing between 100 to 600 tons per day, designed to elevate your production efficiency to new heights.

Product Introduction
The metallic magnesium production line is a masterfully constructed rotary kiln, meticulously engineered to cater to the specific calcining needs of dolomite and the rigorous process requirements of the esteemed Pidgeon method for magnesium smelting. This kiln stands as the cornerstone of the dolomite calcining system, ensuring unmatched efficiency and precision. products produced by this cutting-edge rotary kiln exhibit remarkable stability and uniform quality, featuring high reactivity and minimal loss on ignition, it adeptly fulfills the stringent criteria of the Pidgeon method for magnesium smelting. This innovative design enhances the magnesium extraction rate and optimizes silicon utilization, markedly reducing production expenses and metallic magnesium consumption,. It emerges as the vital equipment for dolomite calcination in the magnesium manufacturing industry.
The complete process of magnesiumsmelting unfolds through a series of purposefully crafted stages: starting with raw material storage, progressing to dolomite calcination, grinding, and briquetting, and culminating in reduction and refining. Initially, the raw dolomite is broken down into 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 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, further refined, cast into ingots, and subjected to surface treatment to produce finished magnesium ingots.

Product Advantages
1) Fuel combustion equipment: Features state-of-the-art energy-saving burners that automatically regulate air distribution, and improve thermal efficiency.
2) A vertical preheater at the rotary kiln's end exquisitely utilizes the high-temperature flue gas from the kiln's combustion to preheat materials,. This groundbreaking approach allows the materials to commence partial decomposition within the preheater,, thereby significantlyincreasing system output and improving thermal efficiency.
3) A vertical cooler at the kiln's forefront expertly harnesses the heat from the kiln's high-temperature whitened material to preheat the secondary air to an impressive 650°C, further boosting thermal efficiency and ensuring exceptional economic returns.
