为了使锤式破碎机，特别是用于粉碎废物材料，所述壳体设置的覆盖有材料入口和与分级光栅（7）的材料出口（12）（1），其中，锤转子（2）可旋转地安装，除尘最佳 能够适应实际需要，是在轴（10）中提供的Gutaustritts（12）的区域中的至少两个，一个在另一个中的转子腔室（21 10）的旋转方向后方的细分已被提出。

In order for a hammer crusher, especially for crushing scrap material, which is provided from a covered with a material inlet and a with a classifying grating (7) material outlet (12) housing (1), in which a hammer rotor (2) is rotatably mounted, dedusting optimally be able to adapt to the actual needs, a subdivision of the region of the Gutaustritts (12) provided for the shaft (10) in at least two, in rotor rotation consecutive spaces (10,21) is proposed.
