This high-temperature rotary kiln is engineered for calcining magnesium powder using heated air, featuring a specialized variable diameter barrel design optimized for magnesium oxide production processes.

• Three-zone design: transition, burning, and cooling zones for complete material processing
• 65 tons per hour production capacity for high-volume operations
• Operating temperature up to 1250°C for optimal calcination
• Advanced thermal technology enhances material quality and abrasion resistance
• Increased material layer thickness and rotation speed ensures even heating
• High thermal cycle utilization and thermal efficiency
• Reduced fuel consumption, power usage, and production costs

The kiln operates on roller support with wheel stop control, facilitating material mixing through rotation. Heat transfer occurs via flame radiation, hot air convection, and kiln brick conduction. Materials progress through the inclined rotating barrel, undergoing complete processing from entry to cooling.

Premium raw materials (30-40mm) undergo calcining, cooling, grinding, and molding stages. The processed materials are then mixed with ferrosilicon and fluorite powders, reduced at 1200-1250°C under 1.33Pa vacuum conditions to produce magnesium ingots through flux refining, casting, and surface treatment.
