A high angle conveyor includes a frame, a lower conveyor belt, an upper conveyor belt, and a pressing assembly. The pressing assembly includes a bracket coupled to the frame, a roller supported on the bracket, a spring support coupled to the frame, a spring positioned between the bracket and the spring support, and a spring retainer coupling the spring to at least one selected from the group of the frame, the bracket, and the spring support. The spring urges the bracket and the roller toward the upper conveyor belt such that the pressing assembly biases the upper conveyor belt toward the lower conveyor belt.
