A riffle distributor assembly for influencing the travel properties of a material feed stream 42 moving between a pulverizer 14 and a furnace 12 is part of a feed path 36 having one duct 44 A having a branch entry 66 A and another branch duct 44 C having a branch entry 66 C both downstream of upstream passage peripheries UPZ defined between adjacent intake vanes 114 through which the feed stream of the material 42 travels in two segregated portions. A motor drive assembly 58 moves the intake vanes 114 relative to the incoming flow reference axis IFA, whereupon intake areas defined between adjacent intake vanes 114 moves relative to the incoming flow reference axis IFA such that the travel properties of the one portion of material in the one branch duct 44 A are different than its travel properties before the movement of intake areas defined between adjacent intake vanes 114.
