The HMCC pulse jet baghouses comprise a filter chamber, filter bags, clean air plenum, hopper, flap valve, pulse jet cleaning system, system fan, and electrical control panel.

Dust-laden gas enters the filter chamber through the hopper or the bottom open flange. Coarser particles fall directly into the hopper or silo, while finer particles rise to the filter bag surface, where dust is retained by filtration. Cleaned gas passes through the bag openings into the clean air plenum and is discharged to the atmosphere by the system fan.

As dust accumulates on the bag surface and resistance rises to the preset value (typically 1,200 Pa), the time relay or differential pressure controller triggers the sequential controller, which opens the pulse valves in sequence, injecting high-pressure compressed air at high velocity through the blow pipe nozzles into the filter bags. The reverse high-velocity airflow causes sudden bag expansion, dislodging the accumulated dust into the hopper or silo. Dust is discharged via a flap valve or a conveying mechanism. Cleaning proceeds row by row while the remaining bags continue filtering.
