A vertical axis wind turbine has its axis perpendicular to the wind streamlines and vertical to the ground A more general term that includes this option is "transverse axis wind turbine" or "cross-flow wind turbine" For example, the original Darrieus patent, US Patent 1835018, includes both options

The power predictions for ball mills typically use the following form of the Bond equation: = (− Tower mills, often called vertical mills, stirred mills or regrind mills, are a more efficient means of grinding material at smaller particle sizes, and can be used after ball mills in a grinding process Like ball mills, grinding (steel) balls or pebbles are often added to stirred mills to
