Abstract
Abstract An automatic batch weighing system for compounding a series of batches containing predetermined measured quantities of various constituents. The constituents for each batch are successively fed into a batch receiving hopper. The compounded constituents are thereafter mixed in a mixing hopper and delivered to a selected utilizing means. The feeding of each constituent is adjusted by estimating the weight of an unpredictable dribble and by compensating for any deviation in the most recent batch compounded for the selected utilizing means, to average out errors in the series of batches.
