CGD型高壓電選機 High  voltage electrostatic separator

電選機是在電暈絲上供給負高壓直流電源，在電暈電極與接地電極的空間產生電暈電場，由于靠接地電極的整個空間帶電荷，被選物料或礦砂經過電暈電場時獲得電荷的機會相同，而導電率不同，在受到電力和機械力的不同作用下，被選物料或礦砂在電場中落下的軌跡也有區別，這樣對導電率較好的、中等的與不導電的其間的的差異進行分選。

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

電選適應范圍：白鎢、錫石、鋯英石、獨居石、鈦礦石、金紅石、紅柱石、石榴子石、電氣石、沙金礦、鉭鈮礦、黑鎢礦、輝鋁礦、黃銅礦等礦物。上述礦物中在使用重選、浮選、磁選都難以達到合格要求，采用電選后能很好的解決。

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.
