Pulse bag dust catcher is high efficiency energy saving machinery designed by our researcher after several years mining crushing and grinding dedusting and ore powder collecting experience, it can adapted strict dust discharging standard domestic and overseas.

Dust-laden air through the inlet into the next ash bucket by fan powered ,then speed dips, large weight dust particles fall into the ash bucket, fine dust into the cabinet with the airflow ,and out of the discharge outlet after the purification treatment by the sieve of the filter bag.

The dust which separated outer of the surface of the filter bag makes the resistance increases gradually, this time the controller send up signal according to the set resistance range, electromagnetic pulse valve is open, the high-pressure air which in the air bag spray quickly, through the Venturi-tube several times in the first wind-induced ambient air into the filter bag, so the filter bag instant expansion, and shake off the dust fall into the dust hopper by a purge-air role.
