Stone Crusher
Metal Set Stone

Stone crusher is the slowest crusher of all. It's used for making dust, used in the crafting of alloys or duplicate the ore yields.

{A stone crusher takes 32 seconds to crush one ore into dust.}[Needs Verification]

This means that one coal can be used to crush only 1 ore, and that 64 coal are required to crush an entire stack of ore.

{Crushing a full stack of ore takes just over 34 minutes using this crusher.}[Needs Verification]
