you feed your floor sweepings to the DC???

The dust collector is an older model Coral. Italian made. Already replaced and spinning just fine. A 2x6x3/4 piece of poplar got shoved from the floor crap into it during a cleanup. Thankfully nothing hurt or damaged except the impeller.

 

How big of motor is on that one,by the look of the shaft hole it must be 5-10hp?

I know this is a big dust collector. Just wondering if a dust separator before the impeller might have been able to prevent this from happening.

The culprit would have just stopped the piece and allowed the pipe to clog ( major hassle) if there was a separator before the impeller.  Best is to not let floor scraps INTO the system.

Yeah it's big. 5 horses strong.

We try NOT to, lol

Hey Mike, that's shrapnel.  Hate that it trashed it but glad you survived.  Was there an underwear change involved?

Mine is a Griz and has a cross hatch screen in front of the impeller. I would suggest a little reverse engineering to avoid future heart attack.

What am I missing. I don't understand this.

The run of pipe and 20 ft long. A crosshatch screen in front of it allows sawdust to build up and eventually clog the pipe. The system has planer, jointer, sliding crosscut, band saw and tablesaw all hooked up in basement. Not enough cfm's to withstand ANY kind of blockage. Even a sliver of wood starts a pileup. Sawdust flows OK though. Gates in the basement would be a pita.

Seems that cross thatched screens at the points of entry could prevent this from happening without causing any clogs. That's an expensive repair.

They sure cut down air flow fast though.

Still don't understand why a simple trash can separator wouldn't work. Unless all piping is over head.

Man that is a mess. That is some kind of suction to pull that all the way in. 

 

Glad ad no one was hurt. Even at 500.00 it is cheaper than body parts.

Mike,Dragon1, seems to indicate this is a commercial installation that can not be altered.

My first DC system was like this where the fan was pulling on the main duct and exhausting into the cyclone and everything went through the fan. I had plastic, cleaning rags chunks of wood screws etc, hit the fan. never had a problem other than a ping now and then.

When I built my current DC system , I installed the cyclone inlet directly on the main duct from the shop, and the fan inlet on the outlet of the cyclone. Sort of the vacuum cleaner principle. The incoming air flow dumps all the debris before the air hits the fan. The fan blows into the filers, not the cyclone like before.

 

I accidentally sucked a can of 3-in-1 oil into the DC and it ended up in the dust bin not going through the fan.

Herb, that's how I set mine up. My impeller is directed outside and the separator is connected to the impeller unit by a 3' pipe.

yes it is overhead in the basement. comes in the top of the collector

Aha. I see, now.
