<p>The invention relates to a crushing device, which is intended for crushing material. The crushing device includes a frame structure (10) and at least one rotor (11), as well as shredder elements (12), which are arranged to form differently-handed spiral formations (13) on the circumference of the rotor (11). The material fed to the crushing device being arranged to travel through the shredder elements (12), at the same time being crushed into smaller parts as the rotor (11) rotates. Each spiral formation (13) extends from a end of the rotor (11) for partial length (d) of the rotor (11), and the spiral formations (13) are arranged to partly overlap each other, the helix angle (y) of the spiral formations (13) being 10° - 50°, preferably 20° - 45°. The invention also relates to a rotor for a crushing device.</p> |
