磁選機

【產品簡介】

高壓電選機設備：主要應用于粗粒弱磁性礦物（褐鐵礦、錳礦等）粗粒拋尾或精選提純;非金屬礦物（紅柱石、硅線石、藍晶石、石榴石、長石、石英、鋯英石、剛玉、金剛石等）原料及產品的精致加工（除鐵、鈦等雜質）：去除各種磨料產品、催化劑及其它物料的弱磁性有害雜質。

【工作原理】

高壓電選機設備主要由圓筒、輥筒、刷輥、磁系、槽體、傳動部分6部分組成。圓筒由2-3mm不銹鋼板卷焊成筒，端蓋為鑄鋁件或工件，用不銹鋼螺釘和筒相連。電機通過減速機或直接用無極調速電機，帶動圓筒、磁輥和刷輥作回轉運動。磁系為開放式磁系，裝在圓筒內和裸露的全磁。磁塊用不銹鋼螺栓裝在磁軛的底板上，磁軛的軸伸出筒外，軸端固定有拐臂。扳動拐臂可以調整磁系偏角，調整合適后可以用拉桿固定。槽體的工作區域用不銹鋼板制造，機架和槽體的其他部分用普通鋼材焊接。

1.合上總電源開關。待礦倉基本充滿礦砂后，調整溫控儀的設定溫度，撥動K1自動加溫開關，此時系統自動加溫，然后高溫指示燈亮。溫控儀的設定溫度通常在常溫～100C的范圍內調整，根據物料和工況的不同選擇合適的設定溫度。一般情況下，溫控儀的初始設定溫度為60C。

Turn on the main power switch. After the ore bin is full of ore, adjust the set temperature of temperature controller, allocate K1 at automatic heating switch, meanwhile the system is automatically heated, and then high temperature indicator light. The temperature is usually adjusted within the range of  ～100C. Appropriate set temperature is selected according to the different materials and working conditions. As a general rule, the initial temperature of controller is set at 60C.

2．溫升至額定的溫度后，啟動輥筒啟動開關按鈕，撥上調速表上的電源開關，啟動輥筒并調整至額定轉速。

When the temperature rises to a rated value, start the roller switch, turn on the power switch of speed table in order to startup the roller and adjust to the rated speed.

3．輥筒運轉后，啟動高壓啟動按鈕，將高壓調整至額定電壓（一般調至2～2.8萬伏之間）。合適的高壓工作電壓因工況而異。

After running the roller, switch on the high-voltage start button, regulate high-voltage to the rated value (generally between 20000 to 28,000 volts). The suitable high voltage varies due to working conditions.

4．高壓適度調整后，緩慢拉動礦倉的給礦開關至適當的給礦流量，然后觀察出礦倉的分選效果，如果分選過程中高壓場頻繁放電，可適當調低高壓工作電壓。但高壓場偶爾放電屬正?，F象。

After appropriate adjustment of high voltage, slowly pull ore bin switch to appropriate ore flow. Then observe the effect of sorting ore. If discharges electric spark too frequently in the high-voltage field, we may reduce the high-voltage properly, however, occasional high-voltage discharge electric spark is a normal phenomenon.

5．本機可連續工作，如需停機，請先關閉給礦開關，然后關閉高壓開關后，再關閉輥筒調速開關。

This machine can work continuously. If you want to shutdown, please turn off the ore bin switch firstly, then close the high-voltage switch, and finally shut off the roller speed control switch.
