What About A Hammer Mill?

[Anofre]

Would one of these work for milling grain for brewing? :huh:
Its a portable Hammer Mill, 3 point linkage & shaft driven.
Has screens for coarse/cracked to fine/flour.
We use it to crack barley for pigs & cattle. Does 1 ton in about 1 hour (shoveling it in the top by hand)

Im not into AG yet, and I use a little grinder for my steeps, but I cant imagine doing 5kg with it...


What sort of mill do the big breweries use?

I think some places use this kind of thing in conjuction to a mash filter. I think you get too much flour or something for regular lautering techniques... I'm not really sure though, but that's my impression.

This must be used with a mash filter. You get >40% flour from a hammer mill. It cannot be used with either a mash or lauter tun. But the plus side is you can get over 100% efficiency.

So no BIAB?
On the coarse screen you get a cracked barley + about 40% flour by weight, fine is 95% flour.
It's adjustable.
Good to hear it should be OK...

Thinking about Malting our own grain after receiving terrific tips off these forums.


Is a mash filter just a fine mesh to the false bottom of the mash tun?

I remember reading this thread from ages ago, there's a PDF in there from Thirsty that should explain it.

The hammer mill will give you grief as the flour content is too high.
We use the hammer mill to make pelletised horse feed and it creates a huge range of particle sizes.
Traditional breweries use roller mills. These dont grind the grain as such, they crack open the grains so the goodies are available but leave the husks largely intact.
The husks act as the filter in the lauter process.

In short I wouldn't recommend it, but don't let that stop you and let us know how it goes!!

Yes, you could use it for BIAB - but not really for any of the standard lautering methods. The flour and fine grits content will be too high and it will wreck husk integrity... not really much of which matters in BIAB.

Not that it looks practical for homebrewing scale milling anyway... but for BIAB - yes
