Product Description

Metallurgical Dolomite Rotary Kiln Production Line of 100-600tpd

Product Introduction
The metallic magnesium production line Discover the expertly crafted rotary kiln, a marvel of engineering designed specifically to meet the unique calcining characteristics of dolomite and the stringent demands of the renowned Pidgeon method for magnesium smelting. Serving as the linchpin of the dolomite calcining system, this kiln delivers unparalleled efficiency and precision, standing at the forefront of the industry. products The products emerging from this state-of-the-art rotary kiln exhibit outstanding stability and consistent quality., boasting high reactivity and minimal loss on ignition-effortlessly meeting the rigorous standards of the Pidgeon method for magnesium smelting. This design not only improves the magnesium extraction rate but also enhances silicon utilization, significantly reducing production costs and the consumption of metallic magnesium.. It stands as the indispensable equipment for dolomite calcination in the magnesium manufacturing sector.
The complete process of magnesiumsmelting unfolds through a series of meticulously orchestrated stages: beginning with raw material storage, advancing through dolomite calcination, grinding, and briquetting, and culminating in reduction and refining. Initially, the raw dolomite is transformed 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 create a cohesive dough, which is placed into heat-resistant stainless steel reduction tanks. Within the reduction furnace, the temperature is meticulously maintained at 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 yield finished magnesium ingots of the highest quality.

Product Advantages
1) Fuel combustion equipment: Features cutting-edge energy-saving burners that automatically manage air distribution, and maximize thermal efficiency.
2) A vertical preheater at the rotary kiln's end optimally utilizes the high-temperature flue gas from the kiln's combustion to preheat materials,. This innovative approach allows the materials to begin partial decomposition within the preheater,, thereby significantlyboosting system output and enhancing thermal efficiency.
3) A vertical cooler at the kiln's forefront fully leverages the heat from the kiln's high-temperature whitened material to preheat the secondary air to an impressive 650°C, further enhancing thermal efficiency and ensuring outstanding economic returns.
