High-Efficiency Roller Mills Industrial Efficiency

Horizontal roller mills use 65-70% of the energy used in ball mills. Roller press (high-pressure grinding rolls): In this technology materials are crushed between two counter-rotating rollers. These rollers are up to 2 m in diameter and 1.4 m long. Roller presses use 50-65% of the energy used in ball mills.
