    Primary Bowl Feeder Design & Purpose
    The Primary Bowl Feeder is specifically designed to aid in the in-feed ore processing to eliminate the precious metals in the slurry from concentrating within a specific area of the feed mechanism.  By creating a condition in the slurry feeding that eliminates the precious metals from congregating in a specific area of the bowl during operation, it allows the Concentrator to use its full circumference on recovery, rather than only a section of the bowl.
