Abstract
An impact mill equipped with transmission machinery (10) to rotate two coaxial rotors (16, 18) of a rotor apparatus (12) by means of one single driving apparatus (14). The transmission device includes, according to one alternative, a secondary shaft (32; 36b) equipped with a gear pair (28, 30) or a conic gear (29). The first gear (28) rotates a gear (24) at the shaft (20) of the first rotor (16), and the second gear (30) rotates a gear (26) at the shaft (22) of the second rotor (18), but in the opposite direction or at a different speed. The conic gear (29) rotates the gear (24a) at the shaft (20) of the first rotor (16) in one direction, and the gear (26a) at the shaft (22) of the second rotor (18) in the opposite direction.

16. An impact mill, comprising
a driving apparatus, a rotor apparatus comprising two coaxial rotors with shafts wherein a first rotor is equipped with blades having impact surfaces and which blades form one or more, typically at least two rings coaxial with said first rotor, a second rotor is equipped with blades having impact surfaces and which blades form one or more, typically at least two rings coaxial with said second rotor, and the rings of the first and second rotor are arranged in an intermeshed fashion, wherein the impact mill further comprises transmission machinery arranged to distribute rotating motion generated by the driving apparatus to the shafts of both of the rotors to rotate the same.
