In a method and means for mixing and homogenizing bulk material such as lump ore and ore concentrates, in which a mixing heap is formed by dumping the material as a large number of layers one on top of the other, said mixing heap thereupon being dug off over the entire height, in which for forming said mixing heap the material to be dumped in layers is fed by a digging machine onto a belt conveyor system and is dumped from this system by a longitudinally moving dumping machine onto the said mixing heap, the material during transport to the dumping machine passes through a throughflow hopper, from which it is discharged in a constant flow, and the speed of the digging machine is controlled in dependency upon the filling of this hopper by special mechanisms, preferably comprising a metering device below the hopper, weight signalling means, weight-to-volume converting means, and special supports and controls. |
