The first all grain batch I brewed was something I ordered from morebeer.com and had them crush it. I don't recall seeing broken grains, they all seemed intact.
After that I got my grain from the local shop and this is how it was crushed:
Does that seem excessive? I didn't have any stuck sparge issue but I did go over the estimated pre-boil gravity by 5 points (add to that greater than expected boil-off and the OG was 8 points higher than expected).
