Default Hopper design for Crankandstein?

Hi.

Just got the Crankandstein 3D before christmas, and got a nice drilling machine for christmas, that is originally ment to be used for mixing cement and concrete. So its slow and strong.

I'm now trying to design a hopper for the mill and have been looking around for a good design. What i would prefer is somethin that will fit easily on top of a 30 liter bucket. And with this design I'll have to fit the mill and the drilling machine on the topside of a plate, that will rest on the bucket when milling.

One thing I've noticed in the different designs I've found, is that there is a difference in how wide people make the hole in the hopper, right where the malt enters the mill. What would be the optimal size of this hole?



Regards.
Lars.

I'm kind of partial to the Barley Crusher design. Try to replicate that. Sorry, couldn't resist.

FYI - the BC's hopper is wide open all the way across the rollers.

I wouldn't recommend anything other than a 5 gallon water jug. Quick, easy, and convenient. That's what I use with my 3 roller.

Yes. But how wide is it the other way? Thats where I've seen a difference. It must give a difference in how much malt is fed to the mill all acrossthe rollers?

This sounds easy made. Do you have a drawing or picture of this design. Especially how its designed where its attached to the mill.

Ah, gotcha. I'll measure and try to post up a pic of what the inside of the hopper looks like.

Doesn't show the hopper, but you can see where I cut the round hole. As far as the width of the slot, keep it narrower than the apex of the top rolls.

Here's a pic of the inside of the BC hopper. The gap is about 1/2". Hope that helps.

I used a 5 gallon water bottle for mine. I mounted a piece of 2 x 4 on top of the mill into which a 2" hole is bored for the mouth of the jug. I also fashioned a gate valve out of the bottom plastic from the jug so that I can load up the hopper, start the motor, then release the grain. It helps keep the rollers from getting crowded.
