When ore reached the surface, it would follow the railroad tracks from the headframe to the Crusher House. The ore would then enter the Crusher House on one of the two rail routes seen in this view. Once in the Crusher House, the ore would be crushed into seven inch chunks and then sent onto the Trestle to be dumped into the awaiting train cars ...
Block caving is a highly resource-efficient method of underground mining, in which large underground ore blocks are cut from beneath, allowing the ore to collapse under its own weight. After collapsing, ore is drawn through drawpoints and conveyed to a crusher. In DOZ block caving, LHD loaders transfer ore slurry into ore passes leading to chutes.
Blake jaw crushers, also as double toggle jaw crushers, are characterized by the position of the pivot of the swing jaw, which is located at the top of the machine. This design allows for a larger feed size and a higher capacity, making it suitable for primary crushing. The motion of the swing jaw in a Blake crusher is predominantly vertical ...
