Product Description

Metallurgical Dolomite Rotary Kiln Production Line of 100-600tpd

Product Introduction
The metallic magnesium production line is a masterfully designed rotary kiln, engineered with precision to cater specifically to the intricate calcining requirements of dolomite and the rigorous process standards of the renowned Pidgeon method for magnesium smelting. This kiln is the cornerstone of the dolomite calcining system, delivering unmatched efficiency and precision in its operation. products produced by this cutting-edge rotary kiln exhibit unparalleled stability and uniform quality, boasting superior reactivity and negligible loss on ignition, seamlessly fulfilling 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 the quintessential equipment for dolomite calcination within the magnesium manufacturing industry.
The entire magnesiumsmelting process unravels through a series of carefully orchestrated stages: starting with raw material storage, transitioning through dolomite calcination, grinding, and briquetting, and concluding with 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 compressed into balls using a ball press. The calcined dolomite is then evenly combined with ferrosilicon and fluorite powders to form a cohesive mixture, which is placed into heat-resistant stainless steel reduction tanks. In the reduction furnace, the temperature is elevated to 1200-1250°C under a vacuum of 1.33Pa, allowing for the extraction of crude magnesium, which is then further refined, cast into ingots, and subjected to surface treatment to produce finished magnesium ingots.

Product Advantages
1) Fuel combustion equipment: Features advanced energy-efficient burners that automatically regulate air distribution, and enhance thermal efficiency.
2) A vertical preheater located at the rotary kiln's end optimally utilizes the high-temperature flue gas from the kiln's combustion to preheat materials,. This forward-thinking design allows the materials to begin partial decomposition within the preheater,, thereby dramaticallyboosting system output and improving thermal efficiency.
3) A vertical cooler positioned at the kiln's forefront fully harnesses the heat from the kiln's high-temperature whitened material to preheat the secondary air to an impressive 650°C, further enhancing thermal efficiency and guaranteeing excellent economic returns.
