滚筒筛  Trommel

   滚筒筛通常用于大型塑料破碎清洗线的预处理阶段或建筑垃圾、城腐垃圾的筛分，机身内筒采用筛板卷制，并加设匀料装置，在慢速旋转过程中有效地初步筛离砂石、瓶盖或其他固体杂质，有效地减轻后段破碎环节及清洗环节的负荷。筛网孔径可根据客户要求及实际物料定制。

1. As the drum rotates at a low speed, impurities such as stones and sand are gradually screened out.

2. Pre-screening protects the downstream system components and improve washing stage efficiency.

3. Extremely dirty material and large-scale plastic recycling line can be processed in this way.
