I have a barley crusher I purchased from Northern brewer which is great except I find the crush is way to fine. I get great efficiancy with the factory crush but my vorlauf is painfull like really painfull. I can't clear my runnings except at the slowest of a trickle. I am using a 10 gallon cooler with a false bottom and I always use rice hulls just as an added precaution. i have narrowed it down to the crush. What adjustments have others made ? I am picking up a set of feeler gauges to accurately adjust the settings. Any help is greatly appreciated.
