Grain mill design questions
I am making my own grain mill. I have a few options in the design, having to decide quick, so please give me your opinions!
Here is what is set:
Motorized at 15 inches / sec (is what I have found is ideal speed)
Roller(s) diameter of 1.5 inches, aluminum (no steel due to machining capabilities)
Roller or Plate adjustable
What I am trying to figure out is;
Do I do one roller and an adjustable plate?
If so, smooth roller and smooth plate (crush, no hull shredding, potential feed issues) or knurled roller and smooth plate (no feed issues, potential hull shredding)?
Do I do 2 rollers?
If so, smooth rollers (crush, no hull shredding, feed issues?), 1 knurled (fixes feed issues, potential hull shredding), or both knurled (great feed, highest potential for hull shredding)?
So I have a lot of potential combinations. What would be best?
sP / sR
sP / kR
sR / sR
sR / kR
kR / kR
I am leading towards sR / kR so I can have one to feed the grain without as much shredding of hulls. I would go with sR/ sR so I am not shredding the hulls at all, but I am concerned at only 1.5" diameter on both rollers I am going to have grain feed issues.
Thanks for feedback and any ideas!
