That is reached because the velocity of the recent air is more than the terminal settling velocity in the particulate solids. To paraphrase, the strain produced by draft of sizzling fluid (In such cases Warm Air) has the capacity to not merely stability the weight of (along with gravitation power exerted by) the moist mass, but additionally, will be able to raise it upwards versus the gravitational drive.
