Product Description

Metallurgical Dolomite Rotary Kiln Production Line of 100-600tpd

Product Introduction
The metallic magnesium production line is an exquisitely designed rotary kiln, masterfully engineered to cater to the specific calcining needs of dolomite and the rigorous process requirements of the revered Pidgeon method for magnesium smelting. Serving as the centerpiece of the dolomite calcining system, this kiln ensures unmatched efficiency and precision. products crafted by this cutting-edge rotary kiln exemplify superior stability and unwavering quality, featuring high reactivity and minimal loss on ignition, it meets the exacting standards of the Pidgeon method for magnesium smelting seamlessly. This innovative design elevates the magnesium extraction rate and optimizes silicon utilization, substantially reducing production costs and magnesium consumption,. It is the cornerstone equipment for dolomite calcination in the magnesium production industry.
The intricate journey of magnesiumsmelting unfolds through a series of precise stages: starting with raw material storage, progressing through dolomite calcination, grinding, and briquetting, and concluding with reduction and refining. Initially, raw dolomite is crushed to the ideal size (20-40mm), sintered in a rotary kiln, cooled, and finely ground in a ball mill. This powder is then pressed into balls using a ball press. The calcined dolomite is meticulously blended with ferrosilicon and fluorite powders to form a unified dough, placed into heat-resistant stainless steel reduction tanks. Inside the reduction furnace, the temperature is elevated to 1200-1250°C under a vacuum of 1.33Pa, where crude magnesium is extracted, further purified, cast into ingots, and treated to produce finished magnesium ingots.

Product Advantages
1) Fuel combustion equipment: Features the latest energy-saving burners that automatically regulate air distribution, and maximize thermal efficiency.
2) The vertical preheater at the end of the rotary kiln efficiently harnesses high-temperature flue gas from the kiln's combustion to preheat materials,. This groundbreaking method enables the materials to undergo partial decomposition in the preheater,, thereby substantiallyincreasing system output and maximizing thermal efficiency.
3) The vertical cooler at the kiln's forefront fully leverages the heat from the kiln's high-temperature whitened material to preheat secondary air to a remarkable 650°C, further enhancing thermal efficiency and guaranteeing exceptional economic benefits.
