1. A device (10) for mechanically comminuting material conglomerates comprising:
- a comminution chamber (14) having a supply end and a discharge end, which comminution chamber is enclosed by a comminution chamber wall (42) and has at least two portions in succession in the axial direction, in each of which at least one rotor (26, 28, 30) is arranged coaxial with the comminution chamber, each of said at least one rotor having a rotor shaft and having striking tools (38) which extend substantially radially into the comminution chamber at least during operation, the rotors (26, 28, 30) having opposite directions of rotation in at least two successive portions,deflection ribs (48) being arranged annularly on the inside of the comminution chamber wall, characterized in thata delivery cone (12) is arranged above the comminution chamber (14) on the supply end and covers the central region of the rotors,in that an inlet funnel (11) is arranged above the delivery cone (12), an inlet area of adjustable size (d) being formed between the inlet funnel and the delivery cone, andin that an air stream device for guiding a particle/air mixture produced in the comminution chamber is arranged connected to the comminution chamber, which air stream device has at least one fan rotor (31), which is arranged coaxially with the axis of the comminution chamber and has its own shaft (33), which is driven by its own fan drive so as to rotate the fan rotor independently of the rotors.

Abstract
A device (10) for mechanically comminuting material conglomerates. The device includes a comminuting chamber (14) having a feed side and an outlet side, surrounded by a chamber wall with rotors (26, 28, 30) each including a rotor shaft and striking tools (38) extending radially into the comminuting chamber. The directions of rotation of the rotors (26, 28, 30) are opposite in at least two consecutive segments. An air stream device (31, 37, 39, 41) for leading a particle/air mixture out of the comminuting chamber (14) is arranged in connection with the comminuting chamber.
