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 cater to the distinct calcining attributes of dolomite. It addresses the rigorous process requisites of the prestigious Pidgeon method for magnesium smelting, serving as the cornerstone of the dolomite calcining system with exceptional precision and efficiency. products produced by this cutting-edge rotary kiln exhibit remarkable stability and uniform quality,, boasting high reactivity and minimal loss on ignition. It seamlessly aligns with the demanding criteria of the Pidgeon method for magnesium smelting, enhancing magnesium extraction rates and optimizing silicon usage. This notably reduces production expenses and metal magnesium consumption,. It stands as the essential apparatus for dolomite calcination within the magnesium manufacturing industry.
The complete process of magnesiumsmelting unfolds through a series of intricate stages: starting with raw material storage, leading into dolomite calcination, grinding, and briquetting, and concluding with 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 is elevated to 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.

Product Advantages
1) Fuel combustion equipment: Integrates cutting-edge energy-efficient burners to automatically regulate air distribution, and enhance thermal efficiency.
2) A vertical preheater at the rotary kiln's end strategically utilizes the high-temperature flue gas from the kiln's combustion to preheat materials,. This innovative technique enables the materials to initiate partial decomposition within the preheater,, thus substantiallyboosting system output and optimizing thermal efficiency.
3) A vertical cooler at the kiln's forefront fully utilizes 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.
