Product Description

Metallurgical Dolomite Rotary Kiln Production Line of 100-600tpd

Product Introduction
The metallic magnesium production line is a masterfully designed rotary kiln, meticulously engineered to cater to the specific calcining properties of dolomite, while meeting the stringent process requirements of the prestigious Pidgeon method for magnesium smelting. This kiln serves as the cornerstone of the dolomite calcining system, offering unparalleled efficiency and precision. products produced by this cutting-edge rotary kiln exhibit remarkable stability and consistent quality, with high reactivity and minimal loss on ignition, it flawlessly adheres to the rigorous demands of the Pidgeon method for magnesium smelting. This innovative design increases the magnesium extraction rate and optimizes silicon utilization, substantially reducing production costs and metallic magnesium consumption,. It is the essential equipment for dolomite calcination in the magnesium manufacturing sector.
The comprehensive process of magnesiumsmelting unfolds through a series of meticulously structured stages: starting with raw material storage, followed by dolomite calcination, grinding, and briquetting, culminating in reduction and refining. Initially, the raw dolomite is reduced to 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 raised to 1200-1250°C under a vacuum of 1.33Pa, where crude magnesium is extracted, further refined, molded into ingots, and subjected to surface treatment to produce finished magnesium ingots.

Product Advantages
1) Fuel combustion equipment: Incorporates pioneering energy-saving burners to automatically manage air distribution, and enhance thermal efficiency.
2) A vertical preheater at the rotary kiln's terminus maximizes the use of the high-temperature flue gas from the kiln's combustion to preheat materials,. This ingenious method allows the materials to initiate partial decomposition within the preheater,, thereby dramaticallyboosting system output and enhancing thermal efficiency.
3) A vertical cooler at the kiln's forefront harnesses the heat from the kiln's high-temperature whitened material to preheat the secondary air to an impressive 650°C, further augmenting thermal efficiency and ensuring exceptional economic returns.
