Rotary Drum Sifter

Available on request

While a Centrifugal Screening Machine mainly processes powders, a Rotary Drum Screening Machine is used for sifting grains and chunks. What makes the Rotary Drum Screener so suitable for this is its relatively low RPM of less than 1 meter per second. This prevents product damage and ensures compliance with the applicable ATEX guidelines.

  • Minimal product damage
  • Highly suitable for food, petfood, and feed
  • In accordance with ATEX guidelines

A streamlined sifting process

We always aim for the most efficient sifting process possible, with as few resources as necessary and the best possible result. As desired, the sifter mesh of the drum is equipped with different perforation sizes to accommodate a variety of products. For example, the finest product particles can be separated in the first part of the sifting drum, to collect the desired product with the right size in the second part of the sifting drum. Larger chunks are discharged and returned to the process through a separate exit. This ensures that as little product as possible is lost in the production process.

  • Both the fine and coarse product can be reused
  • Different perforation sizes
  • Suitable for various products and mixtures
  • Available in multiple construction sizes
  • Production, quality control, and testing all in-house

Key features, options, and models

A Rotary Drum Sifter (1 or 2 decks) can be equipped with different sifting perforations. A product can be divided into two groups (fine enough to go through the perforations and too large to go through the perforations), but for example also in three groups. In this case, at the top of the sifter, finer perforations are used through which only grit can pass. The further down the chunks or grains go, the larger the perforations become. The chunks that are the right size for further processing then fall into the lower section. The oversized chunks remain and can be brought back into the process.

The drum sifters are -depending on the desired capacity- available in various construction sizes. Extra-large types are also available for cleaning raw materials. In this variant only impurities are separated. Rotary Drum Sifters can be used for different materials. In addition to dried granules or chunks, more moist and sticky mixtures can also be processed by a Dinnissen Rotary Drum Sifter.

How it works

The Rotary Drum Sifter is an inclined drum with perforations in the wall. The product enters the top part of the drum. Through rotation and gravity, the product moves further and further down the drum. Only the product that is small enough exits the drum through the perforation holes. Often the perforations at the top of the drum are so small that only the grit can pass through them. Further down, the perforations are as large as the desired chunk or grain size. The oversized pieces remain in the drum. In a Rotary Drum Sifter, the separation is non-destructive, which means that both the fine and coarse product can be (re)used.
