Apparatus is provided to size finely divided catalyst particles so that all of the catalyst particles passing through the apparatus are sized so as to have a maximum particle diameter. The apparatus includes: (a) A sealed cylindrical housing having an arcuate opening cut into its lower surface, (b) A fine mesh screen which overlaps the arcuate opening cut into the cylindrical housing, (c) A hemicylindrical housing attached to the lower surface of the cylindrical housing and defining a cavity in communication with the cylindrical housing, (d) An inlet port in the top center surface of the cylindrical housing, (e) An outlet port in the bottom center surface of the hemicylindrical housing, (f) A shaft rotating axially within the cylindrical housing and having brushes attached thereto which force catalyst particles from the cylindrical housing through the screen and break down catalyst agglomerates introduced into the cylindrical housing.
