Impact crusher, upper rotor and hammer

An impact crusher with dual rotors, an upper rotor (30) and a hammer for the impact crusher are disclosed herein. The upper rotor (30) of the impact crusher comprises two discs on top of each other. The upper rotor (30) comprises a plurality of hammers (40) directed downward towards the outer periphery of the lower rotor (20) which discharges the material to be crushed at high speed. Each hammer (40) has a support shaft (41) extending vertically between a first disk (31) and a second disk (32). The distance between the first disc (31) and the second disc (32) provides a torsional structure for the connection between the hammer and the upper rotor (30). 本文公开了一种具有双转子的冲击式破碎机、一种用于所述冲击式破碎机的上转子(30)和锤。所述冲击式破碎机的所述上转子(30)包括两个在彼此顶部的圆盘。所述上转子(30)包括向下指向下转子(20)的外周的多个锤(40)，所述下转子以高速排出待破碎材料。每个锤(40)具有在第一圆盘(31)与第二圆盘(32)之间竖直延伸的支撑轴(41)。所述第一圆盘(31)与所述第二圆盘(32)之间的距离为所述锤与所述上转子(30)之间的连接提供了扭转结构。
