Muela de piedra perfeccionada que se caracteriza esencialmente por estar constituida en su parte central por una zona de piedra natural, de una sola pieza, y en el resto hasta su periferia, por un aglomerado del tipo llamado piedra artificial, de uniforme constitución en toda la pieza, con lo que se evita que se desprendan partículas de piedra artificial de la muela y se mezclen con los granos sujetos a la molienda.
