Abstract
A vertical shaft processor includes a feed zone utilizing a lock hopper for introducing particulate material to a treatment zone in charges while inhibiting the release of treating fluids from the vessel. A separator receives particulate material from the lock hopper and distributes it across the cross-section of the vessel so as to encourage a uniform cross-sectional flow of various sized particulate material through the treatment zone. Treating fluids are uniformly distributed into the treatment zone of the vessel beneath the separator and through not only linear but also arcuate distributor pipes so that the treating fluids are uniformly exposed to the particulate material across the cross-section of the vessel. A removal grate at the bottom of the vessel includes means for introducing additional treating fluids, which may be cooling fluids, to the particulate material and for removing the material through a central circular opening and an outer ring-like opening to obtain a substantially uniform cross-sectional flow of material from the vessel. A circular pusher bar is supported by circumferentially spaced power cylinders to simultaneously pull and push particulate material into the central and ring-like discharge openings with each cylinder being sequentially operated to obtain an optimal eccentric movement of the pusher bar.
