Product Description

Metallurgical Dolomite Rotary Kiln Production Line of 100-600tpd

Product Introduction
The metallic magnesium production line is an expertly crafted rotary kiln, meticulously engineered to address the unique calcining characteristics of dolomite and the stringent process demands of the esteemed Pidgeon method for magnesium smelting. This kiln serves as the cornerstone of the dolomite calcining system, delivering exceptional efficiency and precision, and ensuring high productivity. products produced by this state-of-the-art rotary kiln demonstrate remarkable stability and consistent quality, boasting high reactivity and minimal loss on ignition, it perfectly meets the rigorous requirements of the Pidgeon method for magnesium smelting. This advanced design boosts the magnesium extraction rate and optimizes silicon utilization, dramatically reducing production costs and metallic magnesium consumption,. It stands as the indispensable equipment for dolomite calcination in the magnesium manufacturing sector, heralding a new era of efficiency and performance.
The complete process of magnesiumsmelting unfolds through a series of meticulous stages: beginning with raw material storage, followed by dolomite calcination, grinding, and briquetting, and culminating in reduction and refining. Initially, the raw dolomite is broken down 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 dough, carefully 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, further refined, cast into ingots, and subjected to surface treatment to yield exquisite finished magnesium ingots.

Product Advantages
1) Fuel combustion equipment: Incorporates cutting-edge energy-saving burners designed to automatically manage air distribution, and enhance thermal efficiency.
2) A vertical preheater at the rotary kiln's terminus optimally harnesses the high-temperature flue gas from the kiln's combustion to preheat materials,. This innovative approach allows the materials to initiate partial decomposition within the preheater,, thereby dramaticallyboosting system output and enhancing thermal efficiency to new heights.
3) A vertical cooler at the kiln's forefront fully exploits 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 guaranteeing outstanding economic returns.
