From Treadmill To Grainmill

[Silver]

A few grain bills have been crushed now and I think I am close to my optimal roller gap setting at 1.8mm.
At 2mm it pulled 6.5kg Aust Ale malt through in just over 4 minutes and gave me 72% efficiency. Last brew set at 1.8mm with 7kg Aust Ale malt and about 20 minutes to crush gave me 88%. Happy with that. In these pics I have 3.6kg Aust Ale malt which I put through twice to see if that may increase my % any. 1st crush 15 min, 2nd crush 3 mins. The longer time factor does not bother me one bit as I am usually getting everything else ready for my mash. I love the the fact that I can flick the switch on and walk away. My first mill was my wife's converted pasta roller, which meant standing their with a drill for 20 mins. I reckon my hopper will hold close to 10kg. This topic follows on from "Lathe operator wanted" topic. There are early stage pics their.

I would have thought 1.8mm gap would be too big. Nevertheless, if it works for you then what ever is going to rock your boat.

Nice pics. I am looking at getting the Mill Master Minimill shortly and motorising it.

PS, I love the hopper.

Looks great Siver, top job.
It's funny how different mills need different settings. I got rid of my Barley Crusher with my brew rig sale & always had my mill set at 0.9mm for my cooler mash tun or 1.2mm for the Rims set up. I purchased a MashMaster MiniMill & at 0.9mm, I couldn't even crank the handle using the same feeler gauge for the Barley Crusher. I can relate to your 1.8mm as this is about where mine is set at.

who made your rollers? they look pretty sexy! :icon_cheers:

the rollers were made from the treadmill belt drive which went from one side to the other. 200mm in the middle was lightly knurled so i cut that in half to give me two at 100mm. i approached a local machine shop and for some tasty beer, he was happy to put the parts in his lathe so i could throw some bearings in. i'll have to look at linking my original topic to this one so you can see the parts as they were earlier.
