  • Iron Ore Crushing & Grinding Controls 911

    Primary CrushingRod Mill Ball MillWet Autogenous Ball MillThe most common control in a primary crusher installation begins with sensing of the bin level below the crusher discharge. This is usually done using a gamma ray source and detector. High level sensors trigger the “no-dump” lights and protect the crusher from damage due to an overloaded bin. Low level sensors not only actuate the dumping lights, but can be used to control the discharge feeder to protect it from direct blows of large or在911metallurgist上查看更多信息
