Ideally, yes add hardened steel strike plate inside barrel. gap your impactors or chains 1/4 inch away from strike plates. You have to allow for material to drift to, put your infeed closest to power side and your outflow opposite so material has time in the drum. Great job so far!
@@AUMINER1 I'll be back, was up testing ground, shot some video for the future. Prospected couple of days in a new area. Fixing equipment. Busy time of year!
Agreed Jim. A couple further thoughts for this build... Try to avoid having the striking bars in the bottom of the drum (but do consider continuous wear plates as needed), as it will lead to dead-bedding behind the bars -- concentrate them where gravity will work in your favor to provide regrind of oversize rather than hanging up. Open up the diameter of the hole the shaft passes through a bit more so you can install seals/bushings on the shaft to keep the dust in the drum and out of the bearing -- same arrangement on the outside bearing block. Avoid creating a straight path for particles to be ejected by the rotor impacts at either input or output, consider a near-axial feed and offset tangential discharge port configuration. Bolts inside the chamber will quickly be worn round any exposed threads peened anywhere they're exposed to impact or deflected material -- plan accordingly for future disassembly and either shield nuts and bolt heads, or use studs or carriage bolts. Take a look at Keith's impact mill for some ideas on air-classification options too. Good luck HH.
I'd put the impact plates as close as possible to the drum, they are going to wear out and you will have a gap in no time. What is going to be your power source? electric or gas ? HP? You can use a piece of rubber tubing with a slice in one side to fit over the pipe and seal it as a gasket. Your cover plate will need bearing to keep the shaft in place - I think i saw two in the box. I have designed and built many of these over the years. I'd be happy to share some tips and hopefully save you a lot of frustration, time and money :)
Thanks AU miner! I am just now getting back to answer the comments, I read them all earlier, but just now had time to go reply. This has been a real learning experience but I think the end results are worth it.
lol, amazing how whiter things get in 4 years (beard). Anyways, I am starting to build a forge and found you when you played with wood (4 years old video). Well, I dont know fi you continued but hopefully you figured things out. Now you are building a rock crusher, hmm, you sound like me, especially that first video I seen If it tickles your fancy, you try to build it and build it with items you have around and so if you find out it isnt your cup of tea, you didnt loose much. So, are you mining silver, gold or both? I am here in NW FLorida and go to locations and get gold. No hard rock, all flood or placer. Been kicking the idea of heading up there as there are alot more places that gold can be found, Plus there are some people up in north Idaho I wouldnt mind seeng. Anyways, its been 5 months, that rock crusher working well for you?
