在选矿厂碎矿工段,矿石中经常混入一些铁钎、矿车销、电耙齿等铁件,当它们进入中碎圆锥破碎机时,往往造成严重设备事故。尽管金属探测器能起“除铁”作用,但是,由于矿石粒度大小不等,当有超过线圈架内径高度的矿石通过时,就使线圈架折断,仪器无法工作。虽然在线圈架前面安装机械的“π”形或“□”形保护装置,但矿石运动的惯性,还有可能折断线圈架。铜山铜矿选厂制造了一个简易的光电保护装置,安装于线圈架的前面,凡有高于线圈架内径高度的矿石通过时,光电保护装置自动发出事故报警信号,有效地消除隐患,保证生产正常进行。
In the ore dressing plant, often mixed with a number of iron ore drill, car sales, electric rake and other iron pieces, when they enter the broken cone crusher, often causing serious equipment accidents. Although metal detectors are capable of “removing iron,” the size of the ore varies in size. When there is an ore passing over the inner diameter of the bobbin, the bobbin is broken and the instrument fails to work. Although a mechanical “π” or “□” shaped guard is attached to the front of the bobbin, inertia of the ore may break the bobbin. Tongshan copper processing plant to create a selection of simple photoelectric protection device installed in front of the bobbin, where the height above the diameter of the bobbin ore through, the photoelectric protection device automatically issue an alarm signal to effectively eliminate hidden dangers, to ensure Production is normal.
