WhatsApp: +86 18838072829Up until the late 19th century, most millers used mill stones to mill the wheat into flour. Mill stones always come in a pair. Both are large round stones, with a flat top and bottom and are incredibly heavy. The bottom stone, the bed stone, stands still during the milling process. The top stone, or roller stone, rotates on top of the bed stone.
