Product Description

Metallurgical Dolomite Rotary Kiln Production Line of 100-600tpd

Product Introduction
The metallic magnesium production line is a masterfully designed rotary kiln, tailored to the unique calcining characteristics of dolomite and the exacting standards of the renowned Pidgeon method for magnesium smelting. This kiln is the cornerstone of the dolomite calcining system, delivering unmatched efficiency and precision. products produced by this cutting-edge rotary kiln showcase remarkable stability and consistent quality, boasting high reactivity and minimal loss on ignition, it perfectly aligns with the stringent requirements of the Pidgeon method for magnesium smelting. This innovative design elevates the magnesium extraction rate and enhances silicon utilization, markedly reducing production costs and metallic magnesium consumption,. It stands as the essential equipment for dolomite calcination in the magnesium production industry.
The comprehensive process of magnesiumsmelting unfolds through a series of precise stages: starting with raw material storage, followed by dolomite calcination, grinding, and briquetting, and culminating in reduction and refining. Initially, the raw dolomite is crushed to 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 blended with ferrosilicon and fluorite powders to form a cohesive dough, placed into heat-resistant stainless steel reduction tanks. Within the reduction furnace, the temperature rises 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: Features advanced energy-saving burners to automatically regulate air distribution, and enhance thermal efficiency.
2) A vertical preheater at the rotary kiln's terminus optimally utilizes the high-temperature flue gas from the kiln's combustion to preheat materials,. This ingenious method allows the materials to initiate partial decomposition within the preheater,, thereby significantlyboosting system output and enhancing thermal efficiency.
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 augmenting thermal efficiency and ensuring outstanding economic returns.
