Processing Capacity: 1.9-76t/h
Cylinder Capacity: 9-285m³
Ore Rotary Dryer designed for iron, copper, nickel, gold and various metallic & non-metallic minerals. Wear-resistant alloy steel plates and special lifting flights handle large particle sizes with uniform drying and high thermal efficiency. Widely used in mineral processing plants, smelters and mining industries.
Capable of processing over 200 different types of materials, with strong adaptability to various mining,construction, and industrial processing scenarios.
Made of wear-resistant alloy steel, 3-4 times longer service life than ordinary steel. Ideal for abrasive materials like ores.
Large diameter design with optimized internal structure handles high throughput, ideal for large-scale mining operations.
Special lifting flights design ensures full contact between ore particles and hot air, eliminating "wind tunnel" effect for consistent moisture content.
High thermal efficiency reduces fuel consumption by 15-20%. Simple structure with few moving parts minimizes maintenance requirements.
