I have also put about 6 sacks of grain plus various specialty malts through mine with not problems... I motorized mine with a stepper motor and some pulleys I bought at tractor supply and since then I have put close to 200lbs through it with no problems...
I was mistaken too many projects lately... I am actually using an old gear reduction motor from a xerox engineering copier... I have a box of them sitting in my garage so figured hey why not give it a shot.What are you driving the stepper motor with?
A few hundred pounds through my CK too - I think it might need cleaning though, the driven roller was getting sticky. I didnt take it apart and lube it up when I first bought it.

I found that the rollers stick if the cams are not perfectly adjusted on each end to match...it created a bind which makes the roller turn hard/easy/ hard as you spin it.
I may have it gapped too close
Im finding that my CKseems to have the same issues as others have stated.
The crank handle is completely useless. It doesn't even crank when I put grain in it, as the screw just spins on the shaft not holding it in place.
The rollers seem out of wack. When I set the gap and tighten it down, the rollers tighten down further and makes the gap smaller on the sides, but wider in the middle.
I so far have only used it for one batch, as I am worried to try it again. The crush it provided last time, was like oatmeal in the mash tun, and created a LOT of flour.
I may have it gapped too close, and the drill i used wouldn't budge it until i cranked it full speed. I will use a high torque drill and see if that changes anything on it, but I am skeptical at best about it.
There is a flat on the shaft for the screw so it would be pretty damn unlikely that the crank would spin without the shaft..... unless it was assembled incorrectly?
What did you gap it at? I believe I gapped mine at 0.037" (IIRC)
I also measured the run-out on the the rollers at less the 0.005" (Again IIRC....)
My 18V Dewalt spins mine in both low and high gear most excellently.
Here is a video of it - the crush has been excellent - maybe you got a lemon?

I didn't order the handle and have never used. It is true that the adjustment has a little play, but I've been able to finesse it and get the rollers to end up at the gap I want - set it a little wider than you want with a larger gap, and then tighten down to the actual target gap. I've had good luck around .026 with an IGLOO mash tun with a copper slotted manifold, after having tried settings down to 0.019 or so. I think the crush you need seems to vary widely based on your mash tun setup. I did end up buying a beefy drill to run it. I can't say how it compares to more expensive mills, but I've been generally happy.
I hope you can get it to work for you.
There is on mine.... it doesn't run to the end of the shaft though so you cant see it unless the crank is removed... maybe it was something they added or removed from production? I have a pulley mounted to mine now or id take a picture...There is no flat part in the shaft of my grain mill. It just spins. Is the main shaft supposed to have one flat side, and not completely round all the way around it?
I have reset the gap on the mill to be the credit card size, which IIRC its .0037? Anyway.. I bought a new drill over the weekend. Its a low speed high torque drill that goes to a max of 550 RPM.

The new drill worked really well with the grain mill, and provided an excellent crush to help get me to 78% or higher efficiency.
Over all, I am not completely stoked on the manufacturing of the mill, but It does what it's suppose to do. It gave me a very fine crush like in the video example you attached, and didn't get a stuck sparge.

I will take a picture of the shaft of my grain mill. When I look at the picture of the one on their site and look at mine, The only difference was that the screw on the hand crank didn't have the retaining nut.
Meh, I am using a drill now so its a moot point.

I just received a unit on Tuesday and there is a flat on the shaft like you described.

Maybe I got a defective one?
Maybe... missing the nut on the handle assy and no flat machined into the shaft?... I wonder what the odds of that are?
Are you sure it was a "cereal killer" brand mill?
Id start playing the lottery if I were you...
The Cereal Killer mill is made in the USA? I was under the impression it was made in China. Good to know its a US product! I wish it came with a lifetime like the BC.
It is NOT made in the USA... the wooden base is and proudly labeled such to throw people off into assuming the whole thing is.
And since the wooden base is screwed to the mill in the usa it can be considered made in the usa... kind of like the new harleys... final assy here means made in the usa now
As far as my research shows, everything but the wooden base was made and assembled in china.
Thats what I thought... guess i will get a barley crusher then.
