Perhaps I should have said "cartridge filter" instead of canister
type dust collector. Well, seems you folks know what I am talking
As to the question on cleaning cloth bags, the bag type collector we
used was a Handler floor model with Baldor motors, one of which was
2 speed. It was a very nice set up =93except for the filter bags=94.
The best way I have been told to wash the cloth bags is with TSP,
trisodium phosphate. Vacuum as well as possible first then wash the
bags=85 by hand. The reason for tedious hand washing is to contain th=
metal waste and not have it go down the drain. A large plastic
garbage can works. Then, the bags are dried and reused.
The washing slop is allowed to settle over time. A drain installed
on the side of the washing container a little off the bottom helps
to drain the liquid when all the stuff is settled. The sludge is
allowed to dry and goes with the sweeps, etc. for refining.
Truthfully, I left that company before I could get any sort of idea
how worthwhile containing the sludge really was. We did get
excellent refining results from the dust and settled stuff directly
from the dust collector. Vacuuming was done with a shop vacuum with
a bag inside.
The notes from you and Ken are just the kind of info I was looking
for. This should help in our decision to upgrade the collection
system in the shop. Thanks very much.
