Berry's Rotary Sifter and Media Separator for Case Tumblers easily separates cartridge brass from corn cob tumbling media. Just dump your tumbler contents into the rotary sifter and crank the handles. The sifter basket is fully enclosed and keeps dust and corncob from spraying all over the room no matter how fast you crank. No need for a media bucket: All the corncob you can squeeze into the high capacity Berry's 400 Tumbler will fit easily inside this Rotary sifter. For more information on tumblers, see our Berry's Tumbler Page.
