A rolling mill without a gear box, also called a direct-drive manual mill, requires more force to turn the handle and roll metal. Typical gear ratios for reduction gear rolling mills are listed as 6:1, 5:1, 4:1, etc. A rolling mill with a 4:1 ratio requires four turns of the handle for the rolls to complete a single rotation.
