ABSTRACT:
A belt press for dewatering slurries is described having a frame designed to minimize the time, effort and frame stress heretofore encountered in the replacement of endless belts, said press comprising a rigid frame comprised of essentially parallel horizontal and vertical members supporting a plurality of laterally oriented longitudinal rolls upon which a pair of endless flat foraminous belts pass in a serpentine path with dewatered material sandwiched therebetween. The frame is equipped with vertical legs having removable spacers on one side and corresponding elastomeric hinges mounted with pre-stressed bolts, and alignment pins on the other side. Jack means positionable between the sides of the frame, co-operate with the pre-stressed bolts to permit removal of the frame spacers and extraction of the endless belts through the resulting gaps in the vertical legs.
