Driven by the transmission assembly 5, the hammer rollers 62 alternately reciprocate, hammering and pressing. Adjacent hammer rollers 62 rise and fall respectively. When the crushed tea leaves are hammered by the downward hammer rollers 62, they are dispersed to both sides of the axis of the hammer rollers 62. At the same time, when the downward hammer rollers 62 rise, the adjacent hammer rollers 62 fall to continue hammering and pressing the tea leaves dispersed to both sides. Multiple hammer rollers 62 repeat the aforementioned hammering and crushing work, achieving the effect of crushing the tea leaves as thoroughly as possible.
