Waterwheel engineering Britannica

Vitruvius described the first geared vertical wheel for which we have good evidence. This mill is also of major significance because it was the first application of gearing to utilize other than muscle power. This mill had an undershot wheel and unlike the breast or overshot wheels did not make use of the weight of falling water.

Cement grinding Vertical roller mills versus ball mills

The grinding process in ball mills and vertical roller mills differ fundamentally. In a ball mill the comminution takes place by impact and attrition. The comminution in the vertical roller mill takes place by exposing a bed of material to a pressure sufficiently high to cause fracture of the individual particles in the bed although the
