A portable feeding and crushing unit which can move on its own or often be installed in a stationary position. The unit has a feed chain (often referred to as a flight chain) inside a shallow built-on hopper that drags the mined ore into a rotating breaker head (shaft), which has various sizes of breaker heads (known as piks). These piks rotate downward as the chain drags the stone or ore into it, crushing the ore to various sizes depending on the height of the mounted rotating breaker head.
