Product Description

Introducing the Metallurgical Dolomite Rotary Kiln Production Line, an exceptional system capable of processing between 100 and 600 tons per day, designed to transform raw materials into top-quality calcined dolomite efficiently.

Product Introduction
The metallic magnesium production line This production line features a meticulously engineered rotary kiln, crafted with precision to meet the unique calcining characteristics of dolomite while adhering to the high standards of the esteemed Pidgeon method for magnesium smelting. This kiln is the core component of the dolomite calcining system, ensuring unparalleled efficiency and precision. products The advanced rotary kiln produces products that exhibit exceptional stability and consistent quality, with high reactivity and minimal loss on ignition, fulfilling all the stringent requirements of the Pidgeon method for magnesium smelting. This innovative design enhances the magnesium extraction rate and optimizes silicon utilization, significantly reducing production costs and the consumption of metallic magnesium,. It is an indispensable asset in the dolomite calcination process within the magnesium manufacturing sector.
The complete magnesiumsmelting process unfolds through a series of well-orchestrated stages: beginning with raw material storage, followed by dolomite calcination, grinding, and briquetting, culminating in reduction and refining. Initially, 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 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 raised 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: Utilizes state-of-the-art energy-efficient burners designed to automatically manage air distribution, and 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,. This advanced approach enables the materials to initiate partial decomposition within the preheater,, thereby significantlyenhancing system output and boosting 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 substantial economic returns.
