Rules take the fun out of everything
I don't know how to do your job, but my book says you're doing it wrongSounds like MSHA logic or should I say lack thereof!! Brings old memories of dealing with mindless assholes. Years ago we had a MSHA inspector touring the plant, he pulled his amprobe out his pocket and hooked it over a cord hanging down from a conveyor motor. I badly wanted to ask him how many amps it was pulling, but I thought, nah, just leave it alone. For those that don't know an amprobe will only read amps off of one conductor of said cord. In other words in motor junction box or back at the mag starter.

That's the premise that most of these inspectors work on. They know nothing about the job you are doing, but according to their book, it is wrongBeing retired from crushers/IUOE for 15 years I no longer do my job. What does your book say is wrong?

Thank you

Great info! Thanks!EK, IMO the less the output of the plant you get then more than likely the smaller the rock it will take. Between trying to snag a niche market and keeping portability to a minimum # of loads, it's going to be difficult to satisfy both. As to the contractor feeding the plant, that can get sticky if you have a loader operator that thinks he's smarter than the plant man. You have to have an understanding out the gate that your plant man will take suggestions but his decision is final. Been there, done that too!!
Understand I'm not touting my idea as best. With shot rock(it's what I call basalt) the size you'll get I think a small jaw, say 20"x30", with no attached feeder and a Texas feeder(google it) would break it down enough for the small all in one unit less a feeder. The Texas feeder could be hyd powered off the jaw hydraulics. The Texas feeder could be set up with a removable dual wheel axle and removable hitch so it can be towed behind your service truck if it's big enough or it could be fitted with a fifth wheel pin. The fifth wheel pin would work best as you can load the hoe, take it to the next job, unload it, drop the lowbed and go back for the feeder. With the Texas feeder it eliminates hinged wing walls on the jaw unit and a ramp isn't needed so the loader can dump in the jaw mounted feeder. If the under jaw conveyor isn't high enough to feed the all in one it can be hinged and extended to reach and the hoe can fold it in and out for moves.
By my count: 1st load--- Texas feeder if you choose to load it, 2 product conveyors for the all in one unless it comes with it's own stacking conveyors and what ever support eqpt will fit.
2nd load--- Jaw
3rd load--- all in one
4th load--- whatever is left
5th load--- and, of course, the hoe
Don't know the size of your track hoe but it will be needed to erect and take down the Texas feeder.
This what I visualize as the best fit for what you want to do. Hopefully others will have better ideas.
Another problem that will crop up with the contractor loader hand is getting him educated as to how big a rock the jaw will break without the plant man having to crawl in and break it enough with a double jack. Been there, done that also!!
HTH,

I can remember 2 guys with ropes tied around their waist crawling down into the area above the jaw. Now the jaw is still running as they rest their feet on a 2 inch perch as they wrap a cable around a rock jammed in the feed. The excavator would pull up on the rock to make it flip down into the jaw. I asked why they didn't stop the jaw, and got takes too long! By the time it stops, and starts up again gotta keep the screens full young fella. Plus if it falls while you are shutting down it will jam. I was so glad when they put a hammer for breaking rocks like that on the feeder. I couldn't tell who was worse him for sending them in, or them for doing it. He lost a man in the 60s when he went through the rolls. By the time they got her stopped, he was in it up to his rib cage. It was before my time, but I thought they said they were getting ready to build the rolls on an old 544.they were bumping her ahead or something and buddy fell in.EK, IMO the less the output of the plant you get then more than likely the smaller the rock it will take.
