The milling costs per Mg of fuel in both systems are similar. However, with the same dimensions of the milling systems, the capacity of the roller system is about 15%–20% higher. Another advantage is the shorter renovation time, which is about 7–14 days for the ring-ball system, while for the roller mill, only 3–7 days.

Ball and Race Mill (Figure 4.10): In the ball-and-race mill, balls are held between two races, much like a large ball bearing. The top race or grinding ring remains stationary while the bottom race rotates. As the coal is ground between large diameter balls and the ring, the balls are free to rotate on all axes and therefore remain spherical.

The ring and roller are forged by special material with high utilization. Under the same grinding material and finish special size, the lifecycle of spare parts is about one year, which is 2-3 times longer than an impact mill or turbo mill. Furthermore, the lifetime can reach 2-5 years for grinding calcite carbonate.
