Abstract
In a chisel-type convergence for a chip bin in a wood chip pulping process and system, an improvement in uniformity of discharge of the chips from a chips bin or the like is provided. The bin includes a conventional hollow substantially right circular cylindrical first, upper, body portion, a second, hollow transition, portion connected to the bottom of the first portion, and a third transition portion, below the second portion and above a metering device, such as a metering screw or a star-feeder. The third transition operates less than full of chips, and provides relief from chip compaction. The third transition portion may include stationary or movable baffles, and/or a metering screw may be provided which can pivot downwardly in order to minimize or eliminate the thrusting force against the bin or upper chips to facilitate discharge.
