Abstract

A crushing state determination device comprises a determination unit that determines the state of an object-to-be-crushed inside a crushing chamber. The determination unit: obtains a prescribed value pertaining to a revolution orbit, relative to a central axis of a main shaft concavity; and determines the crushing state inside the crushing chamber by comparing prescribed parameters obtained from a revolution orbit estimated from the prescribed value, to a reference value.
