Mining Conveyors... Who Typically Designs Them
(OP)
Who typically designs mining conveyors and hoppers?
1. Civil Engineers
2. Civil Engineers w/ PE
3. Mechanical Engineers
4. Mechanical Engineers w/ PE
5. CAD Technicians
I'm trying to figure out if these are typically engineered, and if so, by whom. Are PE stamps required?

Learn from the mistakes of others. You don't have time to make them all yourself.

Project specifications are usually performance based.

I worked on the interceptor tunnels down the west side of Manhattan and I got to design the hopper that the skip hoist dumped into. At the time, I worked for the contractor (Perini), and the headframe and skip hoist was designed by Mayo Tunnel and Mining Equipment. The muck (tunnel spoils) spilled all over the place so the Project Engineer let me design a hopper to catch it. I was only a draftsman at the time. The biggest challenge was to design for impact loads from large falling rocks. We used T-1 steel for abrasion resistance. The rest was simple structural.
We usually have specialty equipment manufacturers design and build this stuff. I'm afraid to tell you who they hire, but their shop drawings come from everywhere from China to France.

The problems that you encountered in Manhattan could easily have been avoided had the designs been scrutinised by someone like myself with 30 years mining experience. ANY splillage at all at the skip /dump interface is intolerable for both production and safety reasons. Mining is easy if you have the experience to know what doesnt work. The trouble is too many people, without practical experience, are of the opinion " How difficult can this be?" Use of abrasion resistant steel is pretty well ubiquitous and rock transfer points, especially in pre cambrian rock which cover something like 60% of Canada.
RE: Mining Conveyors... Who Typically Designs Them
I totally agree with you on the advantage of experience. Especially in specialties like mining - there are so many thing to consider in design as you indicated. Our problems in Manhattan were indeed due to lack of specific experience machine tunneling the rock (mica schist). This was the first successful mole in the City and we had teething problems.
You probably noticed that I was a draftsman when I designed that stuff - not really qualified but everything worked.
So in my response to the OP, my experience is that, in reality, everyone listed (qualified or not) designs this machinery, but probably the most qualified would be a mechanical engineer (with appropriate experience of course).

Thanks for the feedback.
