Yeah the equation I developed (aka made-up, but I'm allowed to do that cos that's my job) is pretty loose. It's based on the volume swept by the rollers, and so there are huge variations depending on all the factors I initially mentioned.Ducatiboy stu said:Well my mill, 2 roller @ 50mm x 200mm spinning at 180rpm gets thru 5kg in about 1 minute
Just simple facts. Nothing else.TheWiggman said:Yes Stu we all know how good your mill is...

You Da MAN.... :super:klangers said:Using my previous equation,
Roller slip factor: 1.4
Roller diameter: 50 mm
Effective roller length: 200mm
Grain density: 500 kg/m3
Mill speed: 180
Pi: (our good mate 3.14)
Mill gap: 3mm
3.14*50*200*180*3*500/((1000^3)*1.4)
= 6 kg/minute
Damn. That's pretty close to reality. I've still got it! :beerbang:
Yeah Tony built it.TheWiggman said:Just fishing for a bite Stu But I certainly have heard about your mill before. I think you built it with Tony? My mill takes about 20 mins for 5kg, but that involves 3 children and a hand crank and halfway through a cranky dad.
3mm gap seems wide klangers, on the home scale I would have expected a gap of 1mm (0.9mm personally) which would have a significant impact on the result.
Yeah fair enough - just change the mill slip factor to compensate in the above examples. We have to "calibrate" the equation with real life examples, so to speak.TheWiggman said:3mm gap seems wide klangers, on the home scale I would have expected a gap of 1mm (0.9mm personally) which would have a significant impact on the result.
