Product Description

New Technology Energy Saving Dolomite Stone Magnesium Production Line for Magnesium Plant

Product Introduction
The metallic magnesium production line is a specially designed rotary kiln, meticulously developed to meet the unique calcining characteristics of dolomite and the exacting process requirements of the renowned Pidgeon method for magnesium smelting. This kiln stands as the pivotal equipment in the dolomite calcining system, ensuring maximum efficiency and precision. products crafted by this rotary kiln exhibit remarkable stability and uniform quality, boasting high activity and minimal ignition loss, perfectly adhering to the rigorous process requirements of the Pidgeon method for magnesium smelting. This not only enhances the magnesium extraction rate and silicon utilization but also significantly reduces the production costs and consumption of metallic magnesium,. It is, without a doubt, the quintessential equipment for dolomite calcination in the magnesium industry.
The comprehensive process of magnesium smelting unfolds through meticulous stages: starting from raw material storage to dolomite calcination, grinding, and briquetting, followed by reduction and refining. Initially, the raw dolomite is crushed into suitable sizes (20-40mm) using a crusher, sintered in a rotary kiln, cooled via a cooler, and ground into a fine powder by a ball mill. This powder is then pressed into balls by a ball press. The calcined dolomite is subsequently mixed evenly with ferrosilicon and fluorite powders to form a dough, which is placed into heat-resistant stainless steel reduction tanks. In a reduction furnace, the temperature is elevated to 1200-1250°C under a vacuum of 1.33Pa. Here, crude magnesium is extracted and further refined, cast into ingots, and undergoes surface treatment to produce finished magnesium ingots.

Product Advantages
1) Fuel combustion equipment: Incorporates cutting-edge energy-saving burners to automatically regulate air distribution, and boost thermal efficiency.
2) A vertical preheater at the rotary kiln's end optimally harnesses the high-temperature flue gas from the kiln's combustion to preheat materials,. Through this, the materials can begin partial decomposition inside the preheater, thereby augmenting system output and enhancing thermal efficiency.
3) A vertical cooler at the kiln's head fully utilizes the heat from the kiln's high-temperature whitened material to preheat the secondary air to a remarkable 650°C, further elevating thermal efficiency and delivering outstanding economic returns.
