Help me pick an industry

[tomustang]

... watching an episode of dirty jobs ... the name of the material ... a base for some paints, and it's like boot black or boot blank ... It's a rock of sorts that they milled into a finer grain, then bagged it and shipped it. ...

That would probably be the episode where Mike Rowe drops his flashlight and then crawls inside the Ball Mill to retreive it on the show about being a Bone Black Technician ...

... a quick Google search solved that problem.

Would be nice to see their process broken down, cause it looks like a pain in the butt. The system I worked on at the one mill I was at was much simpler and every machine sifted the coarser material right back into the feed system, and we ran a bunch of different mat'l that included plastics, cow bones, wax, rubber mixed nylon, powdered ink, nylon, bullet proof top secret plastic for army vehicles , hard foam, gel (for pills) and elastomers.


I'll have to look for that episode
