Working Principle of Bag Filter. Air-containing fines or dust particles obtained from the milled powder is forcefully introduced into the bag filters. These filters are made up of cotton or wool fabric. Air is introduced under the influence of suction applied on the opposite side of the feed inlet. This enables in the separation of particles.

The reverse flow filter dust collector utilizes cartridge elements that are cleaned by "back flushing" with compressed air. This momentary airflow reversal is induced by a short burst of compressed air similar to pulse-jet bag dust collectors. The compressed air is released from the storage receiver by a fast-acting, high-flow diaphragm valve.
Its working principle is that by using the characteristics of the Laval nozzle, the nozzle can accelerate the velocity of the air flow to a supersonic speed. 13 The high-speed air then interacts with water and realizes the atomization process of water. 14 15
