Good crush from a corona mill

NateKerx · 04-09-2009, 01:39 AM

I read a trick on there somewhere awhile back about putting a washer on each of the bolts on a corona mill.

I finally got around to trying it before milling the grain for my next two brews

Sucess!!

I've actually got crushed husks and cracked grains instead of whole grains mixed with shredded husks and flour!

I get 82-83% with a Corona mill. Once you dial it in there is no need to upgrade, IMHO.

Which bolts? What size washers? Do you have any pictures of this? I just scored a free Corona mill, but haven't used it yet... and I want to get it dialed in.

check out this thread here, lots of infor on corona mills

I have always felt that adding the washers was kind of a backwards way of adjusting the mill?? The large bolt and wing nut at the center of the grinding head should give you all the adjustment you need IMO.

+1 to the thread linked

As for the washers, it seems to depend on the manufacturer of the mill whether or not they're required. The Porkert models definitely don't need it but I believe the Victoria models do.

Yes the victoria models do need it and I agree once you get your gap adjusted the grind quality is excellent. I have mine "bolted" so that I can use a socket bit on my drill to grind. I don't have a bigger hopper - I think to save the drill motor its' best to take 10 second breaks between hopper loads (to reload the hopper). Mine is just temporarily setup on a B&D Workmate type folding utility table. The receiving bucket sits on the footrest and a bungy cord holds the bucket to the table to keep from tipping over.
Oh I almost forgot - the key to not losing grain in my setup is a drawstring shopping bag with the bottom cut off. The drawstring goes on the "out" of the mill and guides the grain into the bucket with no waste and very little in the way of dust production.

My Victoria doesn't need washers. I did have to remove the end piece(attached with a cotter pin) and rotate it a quarter turn to take the wobble out of the grinding plate.

I used washers on my Corona, but really didn't see why they were necessary....I could have achieved as much adjustment of the gap as I needed without them.
I tried flipping the grinding plate to get rid of the wobble (which was horrendous), but it didn't help. What I did was cut a few pieces of metal from a pie plate to use as shims underneath the grinding plate it until it was parallel. Now it doesn't wobble, it rocks!
