Pre-separation Technology for Low-grade Magnetic Ore

With the grade of crude ore increasing declining, pre-separation technology has become an important means of increasing productivity and economic efficiency. Pulley for large-block magnetic ores, box dry magnetic separators and magnetic separators with rotating magnetic field can provide technical solutions for pre-separating ores at various particle sizes ranging 0-400mm.

Case Analysis 1

CT1627(Φ1600x2700)pulley for large-block magnetic ores was applied in China’s Hebei Province, with a separation belt of 2500mm in width and a capacity of 4500t/h and -350mm separation particle size.

Case Analysis 2

CT1424(Φ1400×2400)magnetic pulley was applied in China’s Shaanxi Province, with a separation belt of 2000mm in width, a capacity of 600-800t/h and 50-150mm separation particle size.

Pre-separation of Medium Ore

Case Analysis 3

CTF series box dry magnetic separator was applied for -15mm ore pre-separation, with a capacity of 80t/h in a plant in Shandong, with the tailings rate about 15%, iron ore grade improved by 3-5%, and the recovery rate over 90%.
