Which is more suitable for petroleum coke grinding: the rotary-tooth ultrafine grinder or the ball mill?

The rotary-tooth ultrafine grinder is the better choice, as it enables precise particle size control with ultrafines below 2%. In contrast, ball mills are prone to over-grinding, resulting in excessive ultrafine content. Moreover, the energy consumption of the rotary-tooth grinder is only about one-third that of a ball mill.
