Solve or Prevent Poor Flow

Two costly flow problems experienced in a silo, bin, or hopper are arching and ratholing.. Arching (bridging) occurs when an archshaped obstruction forms above the hopper outlet and stops flow. It can be an interlocking arch, where large particles mechanically interlock to form an obstruction, or a .
