Good morning,
I have a 20hp dust collector with a rotary airlock. I have a problem with the dust backing up in the enclosed hopper and subsequently into the baghouse. I am running moldings so we product a large amount of dust. I have limited clearance under the airlock going into the enclosed hopper. I am considering use of a transfer blower on the discharge side of the airlock in lieu of the enclosed hopper. Theoretically this would allow me to blow the dust into a trailer or larger enclosed hopper to simplify disposal. Is use of a transfer blower acceptable practice for use on the discharge side of an airlock? If so, how do I size the unit? If not, do I remove the airlock and use a transfer blower?
Alternatively, I could use a larger open hopper with current airlock configuration but prefer not to do this.
Thanks for your tips!
Greg
