Y mwyaf a ddefnyddir yn eang yw'r felin pedwar-uchel. Mae angen melin aml-rhol i rolio cynhyrchion teneuach. Mae yna lawer o fathau o felinau rholio aml-uchel, megis melinau rholio chwe-uchel, melinau rholio wyth-uchel rhannol, melinau rholio deuddeg-uchel, melinau rholio ugain uchel, ac ati (gweler melinau rholio).
