Product Description

Introducing the Metallurgical Dolomite Rotary Kiln Production Line, designed to offer an impressive capacity range of 100-600 tons per day, ensuring high-efficiency operations.

Product Introduction
The metallic magnesium production line stands as an expertly crafted rotary kiln, meticulously engineered to seamlessly address the unique calcining characteristics of dolomite and meet the stringent demands of the esteemed Pidgeon method for magnesium smelting. This kiln serves as the cornerstone of the dolomite calcining system, delivering unmatched efficiency and precision at every stage. products produced by this state-of-the-art rotary kiln consistently demonstrate exceptional stability and uncompromised quality, boasting outstanding high reactivity and minimal loss on ignition, it flawlessly caters to the rigorous requirements of the Pidgeon method for magnesium smelting. This advanced design optimizes the magnesium extraction rate and enhances silicon utilization, significantly reducing production costs and minimizing metallic magnesium consumption,. It stands as the indispensable equipment of choice for dolomite calcination in the magnesium manufacturing sector.
The complete process of magnesiumsmelting unfolds through a meticulously orchestrated series of stages: beginning with raw material storage, proceeding through 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 expertly compressed into balls using a ball press. The calcined dolomite is 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 elevated to 1200-1250°C under a vacuum of 1.33Pa, where crude magnesium is extracted, further refined, cast into pristine ingots, and subjected to surface treatment to yield finished magnesium ingots.

Product Advantages
1) Fuel combustion equipment: Integrates cutting-edge energy-saving burners that expertly manage air distribution, and significantly enhance thermal efficiency.
2) A vertical preheater strategically located at the rotary kiln's terminus optimally exploits 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 significantlyboosting system output and enhancing thermal efficiency.
3) A vertical cooler positioned at the kiln's forefront effectively utilizes 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 outstanding economic returns.
