Mills are from two different farms, paid $200.00 each, the motor was screwed on the small mill, the capacitors suffered from exposure to the weather. I replaced the whole motor with a spare 5 hp I had kicking about.
Yes I think that the large hammer mill would work to shred mother boards, if you put a dust collector into the circuit you could capture values. This is one reason I just incinerate then ball mill the chips that I have removed from boards. There is no money in the kitty for a dust collector, besides the amount of boards I get does not warrant the expense.
The pails beside the small "Farm King" mill sold under various brand names and colors. The pails are full of contacts already removed from timers etc, the silver buttons a are still attached and will come off when they are run through the mill.
Because silver has a lower specific gravity than copper, brass and plastic separating this from the other crap is reasonably easy.
Sorry guys the model number is on the backside of the large mill and it's tucked in at the moment otherwise I would be more than happy to post it.
