Underflow Configurations and Considerations

Abstract

The design, operation and mechanical condition of the underflow configuration can, and usually does, strongly impact the separation performance of a cyclone. In reality, the cyclone’s performance is just as good as its underflow design. It is the writers’ observation that about 90% of all cyclone related problems are due to problems associated with the inability of the ‘collected’ solids to properly discharge out the underflow. This can be due to a blockage or bridge of some sort or, more often, gas leakage into the cyclone via the underflow piping because of a poor underflow seal.
