If the existing pulverizer is equipped with 6 or 7 balls, increasing of its capacity is also possible by means of replacing the ball-ring system with the bowl and roller milling device. 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
