Compacting

Compacting bulk material and giving it a new shape

BÜCKMANN’s contract manufacturing services include the performance of various tasks for clients in the fine and speciality chemicals sector. These include sifting, grinding, mixing and compacting powders.

Compacting creates a dust-free product with high bulk density

Fine materials and powders are compacted effectively in our powerful compactor. For this, the material is measured into the compactor and compacted between two rollers under extremely high pressure. The result: firm, compact shapes with high bulk density. The compacted material is not only easier to handle than the dusty powder; its high density saves space and makes it cheaper to transport and store.

Another positive aspect of compacting: powders and bulk materials with low fluidity develop improved flow properties after compacting and are therefore easier to measure.

Compacting prevents mixtures from separating

Normally, only pure materials consisting of a single component are compacted. However, after mixing two components, it can be beneficial to compact the mixture so that it doesn’t separate. This ensures that each unit contains equal proportions of the respective components.

The advantages of compacting bulk material at a glance

  • Increased bulk density
  • Dust reduction
  • Improved pourability and flow properties
  • Simplified measurement
  • Undesired separation prevented


As you can see, BÜCKMANN contract manufacturing is an expedient alternative to in-house production.
BÜCKMANN are the people you want if a product cannot be processed in your company or if in-house processing seems impractical.
