Here are a couple of pictures of the 2" screw conveyor that feeds mill,http://picasaweb.google.com/kevin.ladue/ScrewConveyor/photo#5188941875307268178 conveyor moves 1/2 gallon of malt per minute. Tested mill and conveyor together, mill can crush 1 gallon container of malt per minute, conveyor only delivers 1/2 gallon measure. Looks like a drive ratio change is needed from 4-1 reduction to speed up delivery without exceeding mill flow. Next step is to make a hydrator cone for inside of drop tube to control malt dust. Boxes on floor are the remote water chillers for the glycol cooling system under construction.
