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.

The relative 'efficiency' of horizontal grinding mills compared to other comminution equipment is often debated, and efforts to improve the energy efficiency of these mills is an on-going area of attention for process engineers. The discharge arrangement design affects the material transport characteristics within a horizontal grinding mill.

The on-line torque measurement was used for early measurement of the power drawn by the mill, so that the grinding time could be calculated, to maintain the same amount of energy for all tests (i.e. assuming a constant grinding efficiency).
