This is considered to be a "vibratory" ball mill in contrast to the planetary type.

The main difference between diamond grinding and carbide milling is in the way that the cutting head removes the concrete layer. Diamond grinding uses closely spaced, diamond saw blades that gently abrade away the top surface of the concrete. On average, the diamond cutting media will contact the pavement surface nearly 27,000,000 times per ...

However, in this situation the ball mill has to supply this energy and it has a different (higher) work index than the crusher (ie the ball mill is less energy efficient than a crusher and has to input more energy to do the same amount of size reduction). Hence from equation 7, to crush to the ball mill circuit feed size (x. 2
