VBELT Ball Mill DRIVE. Vbelt or polyV drives are generally used on grinding mills consuming 350 HP or less. Where power exceeds this, drives become so large and motors become special, resulting in an uneconomical application. Generally the driven mill sheave is of split hub construction to facilitate field assembly. Vbelt drives allow use ...
