The conveyor belt may include at least one belt surface configured to engage the at least one drive face. The length of the rib extends along the length of the drum from a first end of the rib to a terminus of the rib proximate the entrance end of the drum. In addition, the drum includes a ring that extends between the terminus of the rib and the entrance end of the drum.
