I've had a barley crusher for 2-3 years now and It's been great. about 4 brews in, it lost that O'ring that helped both wheels spin at the same time... It turned up in my mash tun, but the mill still performed and I was getting 73+% efficiency so figured it wasn't needed. So this weekend I brewed two batches and had nothing but issues with the mill! It would just spin the one roller and no grain would get fed. I never touched the settings since i received it since it was working fine. So in order to get grain to crush I had to widen the gap...then run things through a second time with a slightly finer crush. My efficiency suffered greatly as I came in roughly 10-13 points lower than my target OG.
So I guess that rubber O-ring is really required? or is something else going on here?
