F80 is the feed size to the primary BM; T80 is the transfer size (prim mill product size), P80 is the final product (cyclone overflow) The F80 is the feed to the primary ball mill. The T80 (is the P80 of the primary ball mill and the F80 to the secondary ball mill circuit) is measured at the pipe departing the primary ball mill.

A ball mill is a type of grinder used to combine and grind materials into QDs or nano size using varioussized balls. A planetary ball mill is literally loaded with balls, which is why it is nicknamed a "ball mill."Ball mills like the laboratory ball mill or industrial ball mill work by utilizing the force of the moving balls. They don't require a cutting instrument as a result.

Cobalt Steel Ball End Mills with Two Milling Ends. With better heat and wear resistance than highspeed steel, these cobalt steel end mills can run at higher speeds and provide better performance on hard material, such as iron, hardened steel, titanium, and tool steel. When one end wears out, turn the tool around for a sharp edge.
