Abstract: Grain disintegration process relies on grain division into small parts. It is done in a mechanical way through the cohesion force breaking and the result is particle size reduction and the surface area rise. Energy consumption in grain disintegration process is one of the most important compo-nents influencing the final cost after the raw material’s price and the labour costs. The study was conducted at the following working gaps: 4.0 mm and 3.7 mm between upper rolls, and 1.5 between under rolls. Moisture content of corn grain was at the level of 34.57±0.22%. The rollers speed was 4000 rpm. The unit energy consumption was measured by a system including: converter ME-MI2492 (Metrel) and computer PC. It gives a possibility to receive the results in the form of electric base and measured instantaneous power. Sieve analysis on screenings: 6.4 mm, 4.0 mm, 3.0 mm, 2.0 mm, and 1.0 mm. It was stated that, the size of working gap between rolls influences power consumption of the crushing process. An increase of raw material’s feed rate results in increasing of power consumption
