You can buy many different sizes,or if you are handy do what us country folks do,buy a no22 or no32 meat grinder with hand crank at any hardware store,you can use it as is or get a pully to attach to it and run it to a washer machine motor is what I use,1/2horse to 3/4horse.Been using it since 1968,and just replaced grinder in 2004 do to bearings wore out.It will grind as fast as you can put it in.
