    W artykule przedstawiono przebieg i wyniki laboratoryjnych bada艅 energoch艂onno艣ci procesu rozdrabniania poprzez gniecenie ziarna j臋czmienia odmiany KORU. Wyniki dotycz膮ce wydajno艣ci procesu gniecenia jak i jednostkowego zu偶ycia energii przedstawiono dla sze艣ciu r贸偶nych 艣rednic walc贸w i pr臋dko艣ci obwodowej walc贸w w zakresie od 2 m/s do 9 m/s. Jednostkowe zu偶ycie energii przy gnieceniu j臋czmienia zale偶y od warto艣ci parametr贸w konstrukcyjnych oraz eksploatacyjnych gniotownika i wynosi ok. 10 kJ/kg. Otrzymane wyniki bada艅 poszerzaj膮 wiedz臋 b臋d膮c膮 podstaw膮 rozwoju techniki w zakresie rozdrabniania ziarna zb贸偶 w tym zw艂aszcza j臋czmienia.There have been presented the performance and results of laboratory analysis of grinding process energy consumption by crushing of KORU variety barley grain. The results concerning the productivity of crushing process and unit energy consumption has been presented for different roll diameters and rolls tangential velocity in the scope from 2 m/s to 9 m/s. The unit energy consumption during barley crushing depends on the crusher structural and operational parameters and is about 10 kJ/kg. The results obtained can be considered as a progress in relation to the existing knowledge about cereals grain, in particular barley grain
