The shaft(s) or spiral(s)of a blademill begin with one double pitch spiral flight withreplaceable ni-hard outer wear shoes and AR steel innerwear shoes. Following this single flight is a combination ofbolt-on paddle and flight assemblies, which can be varied,depending on the amount of scrubbing required. The flightassemblies include replaceable ni-hard outer wear shoesand AR steel inner wear shoes. The paddle assembliesare fitted with replaceable cast ni-hard paddle tips.
