But getting the first 98-or-99% collected takes a huge load off the baghouse. A critical part of the cyclone is a long-ish downcomer that allow the material to accumulate and discharge with out disrupting the vortex dynamics. Learned by experience! Also, stacked Posiflate valves in lieu of a rotary airlock.
