Abstract
Abstract A PROCESS IN WHICH RELATIVELY LARGE PRE-MAGNETIZED IRON PARTICLES ARE INTRODUCED INTO A FLUID STREAM TO SCAVENGE SMALLER MAGNETIC PARTICLES THEREFROM. THE FLUID STREAM IS THEN PASSED THROUGH AN ANNULAR SPACE CREATED BY AN OPEN-ENDED CONDUIT SUPPORTED WITHIN A CASING. A TRAIN OF PERMANENT MAGNETS IS MOVED THROUGH THE CONDUIT TO ATTRACT THE SCAVENGED MAGNETIC PARTICLES TO THE OUTER SURFACE THEREOF, AND THE PARTICLES ARE SWEPT ALONG SAID SURFACE BY THE TRAVELING MAGNETIC FIELD TO A PARTICLE COLLECTING CHAMBER.
