Product Description

Metallurgical Dolomite Rotary Kiln Production Line of 100-600tpd

Product Introduction
The metallic magnesium production line is a masterfully designed rotary kiln, ingeniously crafted to address the specific calcining characteristics of dolomite. It meets the demanding requirements of the renowned Pidgeon method for magnesium smelting, serving as the cornerstone of the dolomite calcining system with unmatched efficiency and accuracy. products created by this cutting-edge rotary kiln showcase remarkable stability and unwavering quality., boasting exceptional reactivity and minimal loss on ignition, effortlessly fulfilling the stringent criteria of the Pidgeon method for magnesium smelting. This advanced design significantly enhances the magnesium extraction rate and optimizes silicon utilization, substantially reducing production costs and the consumption of metallic magnesium.. It is essential equipment for dolomite calcination within the magnesium manufacturing industry.
The comprehensive magnesiumsmelting process unfolds through a sequence of precise stages: starting with raw material storage, followed by dolomite calcination, grinding, and briquetting, and culminating in reduction and refining. Initially, raw dolomite is crushed to optimal sizes (20-40mm) using a crusher, sintered in the rotary kiln, cooled, and finely ground by a ball mill. This powder is then pressed into balls with a ball press. The calcined dolomite is uniformly blended with ferrosilicon and fluorite powders to form a cohesive dough, placed in heat-resistant stainless steel reduction tanks. In the reduction furnace, the temperature rises to 1200-1250°C under a vacuum of 1.33Pa, where crude magnesium is extracted, refined, cast into ingots, and surface-treated to produce finished magnesium ingots.

Product Advantages
1) Fuel combustion equipment: Incorporates cutting-edge energy-efficient burners to automatically regulate air distribution, and maximize thermal efficiency.
2) A vertical preheater at the rotary kiln's endpoint optimally employs high-temperature flue gas from the kiln's combustion to preheat materials,. This inventive strategy allows the materials to begin partial decomposition within the preheater,, substantiallyenhancing system output and improving thermal efficiency.
3) A vertical cooler at the kiln's forefront fully leverages the heat from the kiln's high-temperature whitened material to preheat the secondary air to an impressive 650°C, further boosting thermal efficiency and ensuring excellent economic returns.
