Chuanzhong Xuan, Liying Cao, Pei Wu, Yanhua Ma, Ding Han


Hammer mills are widely used for material size reduction in food and feed industries. In this paper, a new hammer mill with separate sieving device has been designed and fabricated, in which the so-called material-circulation layer can not be formed and material being ground passes through the sieve by rotor throwing and air blowing without direct rubbing with the sieve. Thus the new machine has the advantages in high productivity, low energy consumption, low sieve wearing, and especially,  the low product temperature increase, which is favorable to  feed quality and feed preserving.
