Our main sand mixer's gearbox gave out yesterday, right in the middle of a big pour for a municipal grate order.
Heard this awful grinding noise, then nothing. The whole line just stopped. Had to scramble and hand-mix in the backup trough to finish the batch, which added like 2 hours to the shift. The quote to fix it is looking at over $3,500. Boss is not happy. Anyone have a good source for rebuilt gearboxes for a Simpson Pro-Mix 225, or is it just cheaper to bite the bullet on a new unit at this point?

Ever hear about my buddy's mixer that ate its own gears?

Ate its own gears? That's wild! How does a machine even do that? I'm picturing metal shavings everywhere.

Wait, the gears actually got eaten? I mean, I've had mixers that grind or get jammed up, but I'm trying to picture literal gear consumption. My buddy's old KitchenAid (from like 1987) just makes a horrible screeching sound when it's overworked, but it never actually destroys itself. Was this one of those cheap plastic gear boxes or an all-metal commercial thing? I'm genuinely shocked a mixer could just go full Pac-Man on its own guts like that.
