Product Description

Introducing the Metallurgical Dolomite Rotary Kiln Production Line, designed for capacities ranging from an impressive 100 to 600 tons per day (tpd).

Product Introduction
The metallic magnesium production line This is a masterfully designed rotary kiln, crafted with precision to meet the specific calcining needs of dolomite and the demanding requirements of the distinguished Pidgeon process for magnesium extraction. Acting as the pivotal component of the dolomite calcination system, it assures unmatched efficiency and precise outcomes. products The products generated by this cutting-edge rotary kiln are renowned for their outstanding stability and consistent high quality, featuring superior reactivity and an exceptionally low loss on ignition, perfectly fulfilling the stringent standards of the Pidgeon method for magnesium production. This advanced design significantly boosts the magnesium extraction efficiency and optimizes silicon utilization, resulting in remarkable reductions in production expenses and magnesium consumption,. It is the essential equipment for dolomite calcination, a cornerstone in the magnesium industry.
The comprehensive magnesiumproduction process unfolds through carefully sequenced stages: starting with raw material storage, proceeding 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, followed by sintering in a rotary kiln, cooling in a cooler, and fine grinding in a ball mill. This powder is then transformed into compact balls using a ball press. The calcined dolomite is meticulously blended with ferrosilicon and fluorite powders to create a uniform mixture, placed into heat-resistant stainless steel reduction tanks. In the reduction furnace, temperatures ascend to 1200-1250°C under a vacuum of 1.33Pa, where unrefined magnesium is extracted, further refined, cast into ingots, and subjected to surface finishing to produce high-quality magnesium ingots.

Product Advantages
1) Fuel combustion equipment: Features cutting-edge energy-efficient burners that automatically regulate air distribution, and maximize thermal efficiency.
2) A vertical preheater positioned at the terminus of the rotary kiln ingeniously utilizes the high-temperature flue gas from kiln combustion to preheat incoming materials,. This forward-thinking strategy allows the materials to begin partial decomposition within the preheater,, thereby significantlyenhancing overall system output and elevating thermal efficiency.
3) A vertical cooler located at the kiln's forefront thoroughly harnesses the heat from the kiln's high-temperature whitened material to preheat the secondary air up to an impressive 650°C, further increasing thermal efficiency and ensuring excellent economic returns.
