弧板電選機使用及操作
User Manual of Arc-Plate Style Electrical Sorting Machine

一、簡介(Introduction)

        弧板式電選機是在溜板式電選機和篩板式電選機的基礎上改進研製的新式選礦設備,具有耗能小、產量大,易操作等優點,適用於澳州、印尼、越南等地區的鋯英石、金紅石、錫礦石等稀有金屬礦的掃選及精選。
       Arc-Plate Style Electricity Sorting Machine is the new type of mineral processing equipment based on the improvement of Slide-Plate Style Electrical Sorting Machine and Sieve-Plate Style Electrical Sorting Machine. It has the characters of low energy consumption, large output, easy operation, etc. It adapts to the selection of rare metal ore, such as zircon, rutile, tin ore which distribute in Australia, Indonesia, Vietnam and so on.


二、工作原理及結構(Structure and working principle)
  

        本機采用雙排四層結構,每層都有接地弧形溜板(無鏽鋼製),其上部安裝一弧狀帶高壓靜電板(鋁板製),此電極板固定不動(但可調),在接通高壓靜電後,礦物經下礦板溜至接地弧板進入高壓電場區,導電礦物被感應而帶電,吸向電極,但由於受到重力作用,故它的運動軌跡不同於非導體礦而從前方排出,非導體礦也受到電場作用,但不會被吸引而進入下層再分選,複選四次直至礦產品合格。
        This machine has the structure of two rows and four stories in each row. Each floor has an earthing curved slide board (stainless steel). On the top it has an arc-shaped high-voltage electrostatic plate (aluminum), which is stationary (but adjustable). When connected to high voltage static electricity, the ore minerals slip into high-voltage field area via earthing arc plate, then conductive minerals charged by induction and attracted to the electrode. Due to gravity, it is discharged from the front which is different from the non-conductive ore. Meanwhile, non-conductive mineral has also been affected by the electric field, but will not be attracted into the lower re-sorting. The process will be conducted for four times until the minerals are qualified.

 

 

三、安裝(Installation)

       1、本機配有底架,安裝時要求垂直放置。
      2、接地要良好,地線要用銅管或角鋼、水管在室外潮濕處深埋2~3米。
      3、高壓電纜安裝時最好套在塑料管內,以防漏電。
      4、礦倉加熱導線要選用4.5mm2電纜,本機控製櫃裏設有高、低溫開關。
      1. The machine is equipped with chassis and it should be placed vertically when installed.
      2. It should be grounded well. The ground line should be buried with angle iron or water pipe into a 2-3 meters wet underground place.
      3. High-voltage cables should be in plastic tube to prevent leakage.
      4. Ore storage heating wire should be 4.5 square millimeter cable. There are high and low temperature switches in control cabinet.

 

   四、操作(Operation)

      接通電源後,按下高壓開關按鈕,順時針慢慢轉動調節手把,將電壓調至2~3萬伏。
      拉下給料手把,調整給礦量,觀察物料在孤板上分布是否均勻,然後觀察礦物分選效果,因各礦物顏色不同,操作時可根據選出的礦物顏色情況調整分礦板的位置或調整高壓靜電電壓的高低,當電壓高時選出的導電礦物量多,反之,則少。
      Connected to power, press the voltage switch button, rotate adjustment handle clockwise slowly, and adjust the voltage to 20-30 Kilo volts.
      Pull down the handle, adjust the amount of the mine, observe whether the distribution of material is uniform/even in the arc plate, and then observe the effects of mineral separation. Because the mineral colors are different, we can adjust sub-ore mineral board position or the static voltage according to the color selected, when the voltage is high, the amount of conductive minerals will be large, on the contrary, will be less.

   五、注意事項(A point for attention)

      1、本機工作時電極板上帶高壓靜電,在工作中嚴禁接觸電極。如要對電極調整時,必須關掉高壓電源,停機前要先將電壓調節手把調回到零位置,再關掉電源。
      2、對分礦板的調整,必要時可在開機時進行,但操作人員要與電極保持適當距離,以防觸電。(在選礦時對分礦板的調整相對容易,操作人員可根據礦物的運動軌跡的變化調整分礦板)。
      3、本機電控櫃中設有二級保護電路設置,當高壓輸出電流過大時(1.2安以上)會自動停機,以保護高壓發生器。
      1. Electrode is forbidden to touch. You must turn off the high voltage power supply before adjusting the electrode. Make sure the voltage regulator handle back to zero position before turn off the power.
      2. When adjusting separate ore plate, the operator must keep an appropriate distance from the electrodes.
      3. Two protection circuits are set in control cabinet. The machine will automatically be shut down to protect the high voltage generator when the high-voltage output current is too large (1.2 amp. or above).


 

   六、故障及排除(Trouble Shooting)

      如高壓輸出突然停止,原因可能是:
      1、高壓線對地短路;需檢查高壓線是否正常。
      2、絕緣板上灰塵太多,造成使輸出電流過大;必須用高壓風槍清潔處理。
      3、礦鬥出現阻塞;本機每層各有一個出礦鬥,因異物如飛蟲等掉到裏麵會阻塞出料口,使礦物堆積過多會引起高壓放電,必須經常檢查各下礦口,保持礦流的順暢。
      If high-voltage output suddenly stops, there are probably the following reasons:
      1. High-voltage wire is short circuit to the ground; please check whether the high-voltage wire is well.
      2. Too much dust on insulating board, which cause the output current large, please clean with high-pressure air gun.
      3. Ore bucket is blocked. There is an ore bucket in each floor of the machine. The outlet port may be blocked if some unexpected objects (such as insect) fell into it. Please check the outlet port frequently to keep the ore flowing smoothly.
