Working principle for cement plant dust collector:

Short bag life usually comes from the pulsers hitting the bag when the cake is not ready to flake off or the cake has gone too long between pulsing and grown too thick and heavy to clean effectively. This causes not only short bag life but very poor performance. There are usually several basic causes for this:

Incorrect timer settings for the operating conditions: The actual requirement for the optimum timer setting may well change as various product runs change or even seasonally. These settings have to be set carefully to begin with and monitored regularly.
Lack of sufficient storage or compressed air supply near the inlet manifold to supply the required pulse air without collapsing the inlet pressure. With too low an inlet pressure, the mass weight of the air pulse is too low, which then becomes ineffective in removing the cake.
Too small a feed line to the dust collector entry will have the same effect as lack of air supply.
Too small or an incorrect regulator, which is unable to handle the required “Rate of Flow” required by the dust collectors.
All of these are installations or system situations that cause restricted air flow. They occur because, prior to the installation or prior to some operational change, the proper “rate of flow” was not identified for the dust collection action. Feed line sizing, regulator sizing, and air supply all require an identified “rate of flow.” You cannot use “average flow rate.”
