Selection of electric separator
Electrostatic separator is the use of high-voltage electrical field in different implementations mineral mineral separation equipment, mainly for scheelite, cassiterite, titanium, iron ore, zircon, rutile, monazite, tantalum and niobium ore Selected assignments.
The commonly used electric separators in China have ф120×1500 double-roller electric separators, ф370×600, ф320×900, YD-3 and YD-4 high-voltage electric separators. ф120 × 1500 is selected from a two-roll electric mill roll diameter is small, throughput time is short, a lower long-term goals DC voltages (up to 22kW), because while the aliquot is selected from tantalum and niobium ore less effective. The latter electric separators have a high working voltage (up to 60kV), and are suitable for finer ore-mixing granularity, and the sorting effect is better. YD-3 and YD-4 high-voltage electric separators are the largest domestic electric separators with high processing capacity. The technical performance of several high-voltage electric separators is shown in the following table.
