CGD型高压电选机 High voltage electrostatic separator

电选机是在电晕丝上供给负高压直流电源，在电晕电极与接地电极的空间产生电晕电场，由于靠接地电极的整个空间带电荷，被选物料或矿砂经过电晕电场时获得电荷的机会相同，而导电率不同，在受到电力和机械力的不同作用下，被选物料或矿砂在电场中落下的轨迹也有区别，这样对导电率较好的、中等的与不导电的其间的的差异进行分选。

Electrostatic separators supply negative high-voltage DC power on corona wires and generate corona electric field in space of corona electrode and grounding electrode. Since the whole space near the grounding electrode has electrical charge, the chance of obtaining electrical charges when the selected materials or ore sand pass the corona electric field is the same. But electric conductivity is different. Under different actions of electrostatic force and mechanic force, the selected materials or ore sand leave different tracks in the electric fields to tell the differences among those with good conductivity, medium conductivity, and no conductivity.

一、用  途

I. Application

电选适应范围：白钨、锡石、锆英石、独居石、钛矿石、金红石、红柱石、石榴子石、电气石、沙金矿、钽铌矿、黑钨矿、辉铝矿、黄铜矿等矿物。上述矿物中在使用重选、浮选、磁选都难以达到合格要求，采用电选后能很好的解决。

Application scope of electrostatic separation: Minerals such as scheelite, cassiterite, zirconite, monacite, titanium ores, rutile, andalusite, garnet, tourmaline, alluvial gold ores, tantalite-columbite ores, wolframite, argentite, and towanite. These minerals are hardly qualified when gravity concentration, flotation and magnetic separation are adopted. Such problem can be well solved after electrostatic separation is adopted.
