Tips
history
磙 has no standalone modern use; today the rolling sense is carried by 滚 (to roll) and 碾 (to crush). It is a phono-semantic char: the stone radical 石 plus the phonetic 衮, which also gives the sound in 滚.
register
Archaic agricultural vocabulary; found in old farming texts and etymology notes, not modern speech.
