A water wheel is a machine for converting the energy of flowing or falling water into useful forms of power, often in a watermillA water wheel consists of a wheel (usually constructed from wood or metal), with a number of blades or buckets arranged on the outside rim forming the driving car Water wheels were still in commercial use well into the 20th century but they are no longer in common .
The circuit comprises a SAG mill, 12 m diameter by 61 m length (belly inside liners, the effective grinding volume), two pebble crushers, and two ball mills in parallel closed with cyclon The SAG mill is fitted with a 20 MW gearless drive motor with bi-directional rotational capacity
This is an infinite combo deck with a win condition of Flayer Husk + Grinding Station + Salvaging Station resulting in infinite mill Flayer Husk essentially lets you exploit the two stations because while the card itself is an artifact, it also generates a 0/0 germ token with the weapon attached This allows you to grind the artifact, causing the germ token to become a 0/0 again and go to .
