Studies upon breaking the maize grain using a crusher with variable cylinder have been carried out. Grain subjected to the breaking process was of 12, 20, and 30% moisture content. Breaking has been performed applying working gaps of 0.2, 0.5, 1.0, 1.5, and 2.0 mm width as well as cylinder’s speed of 400/400, 400/440, and 400/480 rpm (both cylinders rotational speeds, respectively). Experiments revealed that increasing the rotational speed of one of cylinders in a crusher caused the increase of dusty particles in the achieved product. That increase was observed both at moisture contents change and for different widths of a working gap within the crusher.

Przeprowadzono badania nad rozdrabnianiem ziarna kukurydzy przy wykorzystaniu gniotownika o zmiennych obrotach walców. Ziarno poddane procesowi rozdrabniania było o wilgotności 12,0; 20,0; i 30,0%. Rozdrabnianie przeprowadzono stosując szczeliny robocze w gniotowniku 0,2; 0,5; 1,0; 1,5 i 2,0 mm i prędkości walców odpowiednio prędkość obrotowa walca pierwszego względem drugiego: 400/400; 400/440 i 400/480 obr/min. Przeprowadzone badania wykazały, że zwiększenie obrotów jednego z walców w gniotowniku powoduje wzrost ilości części pylistych w otrzymanym produkcie. Wzrost ten stwierdzono zarówno przy zmianie wilgotności jak i dla różnych wielkości szczelin roboczych gniotownika.
