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 acts as the cornerstone of the dolomite calcining system, delivering unmatched efficiency and precision, ensuring your operations remain at the forefront of industry standards. products produced by this state-of-the-art rotary kiln demonstrate remarkable stability and uniform quality,boasting high reactivity, and minimal loss on ignition. It flawlessly adheres to the rigorous prerequisites of the Pidgeon method for magnesium smelting. This innovative design boosts magnesium extraction rates and optimizes silicon utilization, significantly reducing both production costs and metallic magnesium consumption.It stands as the indispensable equipment for dolomite calcination within the magnesium manufacturing sector.
The complete process of magnesiumsmelting unfolds through a series of meticulous stages: beginning with raw material storage, followed by dolomite calcination, grinding, and briquetting, 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 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 escalates to 1200-1250°C under a vacuum of 1.33Pa, where crude magnesium is meticulously extracted, refined, cast into ingots, and subjected to surface treatment, thereby yielding pristine magnesium ingots.

Product Advantages
1) Fuel combustion equipment: Features cutting-edge, energy-efficient burners that intelligently manage air distribution, and significantly enhance thermal efficiency.
2) A vertical preheater at the rotary kiln's terminus optimally leverages the high-temperature flue gas from the kiln's combustion to preheat materials,allowing the materials to initiate partial decomposition within the preheater,thereby dramaticallyboosting system output and enhancing overall thermal efficiency.
3) A vertical cooler at the kiln's forefront maximizes the heat from the kiln's high-temperature whitened material to preheat the secondary air to a remarkable 650°C, further amplifying thermal efficiency and ensuring exceptional economic returns.
