The first example was a "stirred ball mill" prototype developed by Klein and Szegvari in 1928 [6]. In 1946, this evolved into the modernday "Attritor mill", a vertically operated pin mill that could grind particles even at low tip speeds. Since then, several variations have been manufactured using this design template [7].

The running back was on the field for 61 percent of the offensive plays, with Tyler Allgier at 35 percent and Cordarrelle Patterson at 13 percent. Plus, Smith noted, Robinson's presence in and of itself can be a factor for the offense. "Sometimes, his impact away from the ball can open things up," Smith said in his press conference.

Ballmills are categorized into four types depending on the motion generated to produce momentum in grinding balls and act upon the material with various milling forces. These are planetary, tumbling, vibratory, and attrition mills. Planetary ball mill. Planetary ball mills are simple and efficient in producing ground/pulverized material.

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.
