Grinding something is an example of a physical change, because you are not chemically changing what the substance is, you are only changing the form of it. Another example of a physical change is boiling water, because the water is still water, it's just in a gas form instead of liquid.
When something is grinded it is a physical change not a chemical change.
Crushing a rock does not change the chemical identify of it's constituent compounds. Therefore, crushing a rock is a physical change.
