What functions does a feed bunker have?

The purpose of a feed hopper is to

  • store material store
  • feed
  • dosage
  • and equalization

of the material in the recycling process.

In recycling, the recycled material is prepared for reuse. There are process steps that build on each other. For example, this includes classification and screening using a stationary screening machine or mobile screening plant. NIR sorting and/or magnetic sorting can also be part of the recycling process. The process begins with the feeding of the material.

Feed hoppers are used for this purpose. They store the material. This is filled or fed into the feed hopper using a wheel loader, for example. In addition to storing the material, one of the main tasks of the feed hopper is to transfer the material to the downstream machines. The aim is for the feed hopper to feed the material to the treatment process in the desired quantity.

Large infeed hopper ready for transport to recycling plant

In what sizes and filling heights are feed hoppers available?

From very small to XXL

We manufacture feed hoppers for you in all sizes. We adapt the size and filling height precisely to your requirements. For example, feed hoppers for large-volume materials generally have a larger capacity than those for low-volume materials. We determine the size together with you and in coordination with the technology and machines used.

What materials is a feed hopper suitable for?

Suitable for almost all recycled materials

Feed hoppers are suitable for almost all recycling materials and bulk materials of all kinds. Common applications include scrap metal, electrical scrap, shredded PVC windows, shredded PV elements, slag, incinerator bottom ash, fluidized bed ash, refuse derived fuels, shredded waste wood, compost and biowaste, ASR (Auto Shredder Residue), batteries and much more. Thanks to their very robust and stable steel construction, feed hoppers are also ideal for harsh applications and materials.
