Low voltage LV variable frequency drives VFDs have been applied to applications up to 2500 horsepower HP. Medium voltage MV VFDs have been applied to applications as low as 150 HP. Traditional power system design practice suggests that motor crossover from low voltage to medium voltage is in the 200-600HP range.

Pebble mills are a type of ball mill and are also used to reduce the size of hard materials, down to 1 micron or less. Because of their fairly simple design, ball mills and pebble mills are less likely to need costly repairs unlike other crushing or extraction equipment making them an attractive option for businesses on a budget.
Ball Mill Operation. Ball mills ride on steel tires or supported on both ends by trunnions. Girth gears bolted to the shell drive the mill through a pinion shaft from a prime mover drive. The prime movers are usually synchronized motors. During rotation, a portion of the charge is lifted along the inside perimeter.
The interplay between these forces produces the high and very effective degree of size reduction of the planetary ball mill. Across International gear-drive 4-station planetary ball mills have built-in, reverse and timing functions. High energy ball mills grind down material to sub-micron level in minutes.
