introduction Of Slurry Magnetic Separator
Roller electrostatic separator is a dry physical separation equipment that achieves efficient separation based on the difference in material conductivity. Through the action of a 5~100kV high-voltage electrostatic field, materials with different electrical properties are separated by motion trajectories. Through separation and purification, valuable components are recovered or impurities are removed to improve resource utilization. It specializes in the separation of non-ferrous metal ores, electronic waste, and high-purity quartz sand, and can achieve a purity of 99%. It can be configured with multiple separation stages (2-4 stages) to obtain higher purity products at one time (Achieve separation of three types of concentrates: conductor, semiconductor and non-conductor).
Roller electrostatic separators are widely used in the fields of non-ferrous metal recovery, rare metal separation, and mineral purification, such as: separation of beach sand (separation of titanium, zirconium, rare earth, monazite, and garnet); preparation of high-purity quartz sand (SiO₂＞99.9%), etc. The multi-electrode dynamic adjustment system, wear-resistant intelligent structure, and ultra-low energy consumption make it an irreplaceable green mineral separation equipment in the field of resource recovery and mineral purification. With outstanding advantages such as high sorting accuracy, no water resource consumption, environmental protection, and energy saving, this electrostatic separator is particularly effective in processing fine-grained zircon, rutile, ilmenite, gold, tin, tungsten, tantalum niobium, and other metal or non-metallic ores. JXSC state-of-the-art electrostatic separators feature either two or four rollers (with the four-roller configuration offering higher processing capacity) to maximize mineral separation efficiency for various applications.
working principle of Roller Electrostatic separator
The roller electrostatic separator is mainly composed of high-voltage power supply system, rotating sorting roller, feeding vibration system, ore separation partition and other components.
The material is evenly spread on the surface of the rotating grounded roller through the vibrating feeder. Under the action of the high-voltage corona electrode in the corona discharge area, the material particles with different conductivity are charged with different polarities due to contact charging or induction charging. Under the combined action of electric field force, centrifugal force and gravity, the charged particles move in different directions. Among them, the conductive material: discharges quickly and is thrown away by the roller inertia (parabolic trajectory). Semiconductor material: partially discharged, attracted by the static electrode and presents a medium throwing trajectory. Non-conductive material: keeps the charge adsorbed on the roller surface and is peeled off by the brush. These three types of materials fall into different collecting hoppers to achieve precise sorting.
