Rice bran ball sounds too much like a direct translation from Japanese, and I can't find any hits for it on Google. "Ball" just does not sound right. I think it's more like residue or remnants.

rice bran ball
Explanation: Final separator
Satake began sales of the Final Separator on May 20 of this year. This machine is designed to remove foreign materials after all other rice milling processes have been completed. It can remove those contaminants which arise during processing, including balls of rice bran, insects, and detached germ and other small particles. http://www.satake-group.com/news/090514.html http://www.satake-japan.co.jp/ja/products/ricemill/fs.html
