Working Principle of Bag Filter

	The dust-laden air enters the bag filter bustle.
	The air is uniformly distributed avoiding channeling.
	Initially a coat of material forms on the bags. Subsequently, the coat acts as the filtering medium.
	The dust is accumulated on filter elements while the air passes through the filter bags from outside to inside.
	The accumulated powder is dislodged from the bags by reverse pulse-jet air or by mechanical shaking intermittently. n The dislodged powder falls on bottom cone and is discharged through powder discharge valves.
	The dust free air is sucked by induced draft fan and is exhausted to atmosphere.
	Knockers are provided on conical portion especially for sticky/hygroscopic materials.
