A barrel apparatus for use in treating workpieces with grinding media, comprising a novel rotary barrel provided on its inner peripheral wall with a spiral flight extending lengthwise of the barrel and one or more ancillary flights extending straight or in an extremely modulated spiral form lengthwise of said barrel and intersecting the spirals of said first spiral flight, thereby accelerating the flow of the contents in the barrel to improve grinding efficiency, and further, permitting smooth delivery of the contents even when a small amount of the contents is present in the barrel.
