A chemical change is one that alters a substance's chemical properties. Crushing rock salt only changes its physical shape, chemically it is still rock salt, so it is a physical change.
Plant Is Crushing Rock Crystals A Chemical Or Physical Change. However theres a dispute about whether dissolving an ionic compound like salt is a chemical or physical change because a chemical reaction does occur where the salt breaks into its component ions sodium and chloride in water the ions display different properties from the original compound that indicates a chemical.

2021-2-5 In general a physical change is reversible using physical means. For example, salt dissolved in water can be recovered by allowing the water to evaporate. But the distinction between physical and chemical change can be misleading and confusing at times. In general, anything that does not change the chemical constitution of the substance, is a

Dissolving salt in water may be considered a chemical change or a physical change. If you’re forced to pick a side, most chemists say dissolving a covalent compound (like sugar) is a physical change, but dissolving an ionic compound (like salt) is a chemical change.
2019-5-10 A chemical change results from a chemical reaction, while a physical change is when matter changes forms but not chemical identity. Examples of chemical changes are burning, cooking, rusting, and rotting. Examples of physical changes are boiling, melting, freezing, and shredding. Often, physical
