WSM-04 Centrifuge is rated at 40-60 tons per hour of dry material. Note: Actual capacity and moisture may vary contingent upon average particle size, feed moisture, and particle shape. Centrifuge  screen has a surface area of 1,880 sq.in.(13.06 sq.ft.) Centrifuge gear unit has a ratio of 71 to 1  G Force = Bowl Dia. In inches x RPM squared x .0000142  403 = 36 in. x 887.5 x 887.5 x .0000142 Sheave PD x Motor RPM divided by Gear Unit Pd = Final Speed of screen 10.5 in. PD x 1775 RPM divided by 21 in. PD = 887.5 RPM  Flight speed = final speed of screen divided by gear unit ratio subtracted from final speed of screen  875 RPM = 887.75 RPM divided by 71 = 12.5 (887.75-12=875)
