Product Description

Metallurgical Dolomite Rotary Kiln Production Line of 100-600tpd

Product Introduction
The metallic magnesium production line is a superbly designed rotary kiln, meticulously crafted to meet the unique calcining characteristics of dolomite. It addresses the demanding requirements of the prestigious Pidgeon method, a cornerstone in magnesium smelting. This kiln is the heart of the dolomite calcining system, offering unmatched efficiency and precision. products produced by this advanced rotary kiln exhibit remarkable stability and consistently high quality,, boasting impressive reactivity and minimal loss on ignition. It flawlessly satisfies the rigorous demands of the Pidgeon method for magnesium smelting. This innovative design enhances magnesium extraction rates and optimizes silicon utilization, thereby significantly reducing production costs and the consumption of metallic magnesium,. It is an essential piece of equipment for dolomite calcination within the magnesium production industry.
The complete process of magnesiumsmelting is conducted through a series of precise stages: starting with raw material storage, progressing through dolomite calcination, grinding, and briquetting, and culminating in reduction and refining. Initially, raw dolomite is crushed to ideal 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 create a cohesive mixture, placed into heat-resistant stainless steel reduction tanks. Within the reduction furnace, temperatures rise to 1200-1250°C under a vacuum of 1.33Pa, where crude magnesium is extracted, further refined, cast into ingots, and undergoes surface treatment to produce finished magnesium ingots.

Product Advantages
1) Fuel combustion equipment: Features cutting-edge energy-saving burners for automatic air distribution management, and enhanced thermal efficiency.
2) A vertical preheater situated at the rotary kiln's end effectively utilizes the high-temperature flue gas from combustion to preheat materials with precision,. This innovative technique allows the materials to begin partial decomposition within the preheater,, thus significantlyincreasing system output and enhancing thermal efficiency.
3) A vertical cooler at the kiln's front efficiently utilizes heat from the kiln's high-temperature whitened material to preheat secondary air to a remarkable 650°C, further boosting thermal efficiency and ensuring exceptional economic returns.
