How it Works:

Static Trommel Screens - How it Works
  1. The input material, consisting of a mixture of small and large sized material, is loaded into the hopper.
  2. The material is fed into the opening of the trommel drum via the infeed conveyor.
  3. During operation the drum rotates, so as the material falls in, it’s carried by the rotation and gets pulled up the side wall of the drum, before dropping back down again.

4. This process repeats continually, with the turbulent action causing the small and large sized material to separate.
5. The drum is lined with apertures of a specific size. As the material passes over these, the small material falls through, whilst the large material passes over.

6. As the material travels the length of the drum, all the small material falls through the apertures to the ground, where it can be collected, thus separating it from the large material.
7. Being too big to fall through the apertures, the large material will pass along the full length of the drum and be discharged out the end.
8. Now fully separated from the small material, the large material will fall to the ground, where it can be collected for use or further processing.
