two main hopper types are conical hoppers which operate with axi-symmetric flow and wedged-shaped or chisel-shaped hoppers in which plane-flow occurs. In plane-flow bins, the hopper half-angle a will usually be, on average, approximately 8° to 10° larger than the corresponding value for axi-symmetric bins with conical hoppers.

BULK MATERIALS HANDLING IN THE MINING INDUSTRY

The Challenge ore feeder has an iron hopper that collects ore from the ore bin. Under the hopper is a circular table inclined toward the stamp battery mortar which slowly revolves. The fixed scrapers directs ore into the back of the stamp mortar as the table rotates. The stamp battery regulates the flow of ore into the stamp mortar by ...

Hoppers always check for another hopper or storage block below them before passing items on to a hopper beside it. So what happens in this design is that unless you put enough things to smelt in the chest so that each furnace has a complete stack of items to smelt, any amount of items below the max amount, like one stack of iron ore, would only ...
