Not a pulp mill, but a wood pellet mill. I run the dust grinding area... A one man show till something goes wrong. The real process comes after the silos where we make the dust into wood pellets. We make both heating and bbq. We make excellent bbq pellets, if I do say so myself! BBQ is our main interest. Heating pellets used to be our main business but we are well on our way in the process of converting the business into a primarily BBQ mill.
What would be cool: upon fault to kill all upstream equipment (skipping the hammer mill - > that should never stop) and leaving down stream equipment alone. But, that's a little too big for me right now. If I can turn off here two pieces successfully, I can replicate that method for the rest later... Though the triggering system would need to change, I suppose... Send it to some kind of Cascade...
As for the photos and the like, sure. I have a couple videos. Maybe I can put it up on YouTube... Though the only vids I have are documenting repairs.. Not what you are looking for. I can take one on Monday, then post. I do want to warn you, though... Low tech and messy
