Product Description

Metallurgical Dolomite Rotary Kiln Production Line of 100-600tpd

Product Introduction
In the domain of high-quality metallurgical processes, the metallic magnesium production line by Shandong Bullis Metallurgical Engineering Co., Ltd. represents the pinnacle of technological prowess. This expertly crafted rotary kiln, meticulously engineered, adeptly addresses the unique calcining characteristics of dolomite. It meets the stringent process demands of the esteemed Pidgeon method for magnesium smelting, serving as the vital linchpin of the highly efficient dolomite calcining system. products produced by this cutting-edge rotary kiln exude exceptional stability and unparalleled quality, showcasing impressive high reactivity and achieving minimal loss on ignition, thus flawlessly fulfilling the rigorous requirements of the Pidgeon method. This innovative design significantly boosts the magnesium extraction rate, optimizes silicon utilization, remarkably reduces production costs, and minimizes consumption of metallic magnesium,. It remains indispensable as the cornerstone equipment in the magnesium manufacturing sector for dolomite calcination.
The complete process of magnesiumsmelting unfolds through a meticulous sequence of stages: starting with raw material storage, progressing through dolomite calcination, grinding, and briquetting, and culminating with reduction and refining. Initially, raw dolomite is carefully crushed 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 uniformly mixed with ferrosilicon and fluorite powders to form a cohesive mixture, 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 meticulously extracted, refined, cast into ingots, and undergoes surface treatment to yield pristine magnesium ingots.

Product Advantages
1) Fuel combustion equipment: Integrates state-of-the-art energy-saving burners to automatically optimize air distribution, and thereby enhancing thermal efficiency.
2) A vertical preheater at the rotary kiln's endpoint leverages the high-temperature flue gas from the kiln's combustion to preheat materials,. This innovative methodology enables the materials to commence partial decomposition within the preheater,, thus significantlyelevating system output and amplifying thermal efficiency.
3) A vertical cooler at the kiln's forefront maximizes the heat from the kiln's high-temperature material to preheat the secondary air to an impressive 650°C, further enhancing thermal efficiency and ensuring superior economic returns.
