According to Bond’s Third Theory of Comminution, the work/energy input is proportional to the new crack tip length created during particle breakage and equivalent to the work represented by the product the feed. A crude test

Crushing vs. Impact: How We Define Hazard

Crushing. For crushing, it implies that someone or something is trapped between two elements and where one of the elements is moving. Impact. For impact, it seems closely associated with crushing, but the consequences and situation in which an impact occurs are different from someone being crushed.
