Centrifugal Mill

Available on request

In a centrifugal mill, the material to be ground that is in the mill is swung against a grinding track by centrifugal force. The centrifugal mill is driven by a rotor, which causes the material to move in a circular path. Centrifugal force is also called centre fleeing force, because the objects appear to flee (escape) the center. You can see the same principle in a dryer, where the water is pressed against the drum by centrifugal force and is discharged through the holes in this drum.

  • Long service life and low maintenance thanks to the proven robust construction
  • Optimized for decades for efficiency, capacity, and uptime
  • Hygienic and dust-proof design, also available as EHEDG version

Optimum product refinement with a centrifugal mill from Dinnissen

Our centrifugal mills are ideally suited for very fine product grinding. The mill is suitable for various types of product. Depending on the grinding material and the desired final fineness, various rotor and stator designs are available. These include pins, a turbo motor or, for example, an additional paddle wheel that can keep the grinding path clear during the grinding of greasy and sticky products.  

The relatively high rotor speeds create a lot of air movement. This has a cooling effect on the product to be ground. Since the grinding material does not heat up, the moisture content is maintained. Our milling systems are equipped with extensive filter systems and a fan to ensure air/gas displacement across the centrifugal mill.

  • Suitable for very fine product grinding
  • Simple cleaning due to one-sided bearing
  • Proven robust construction
  • Good accessibility: wear parts can be quickly replaced
  • You can test your products in advance for the desired result in our Dinnissen D-Innocenter.

Key features, options, and models

An important advantage of our centrifugal mills is the very small final fineness that the mills can generate. These cast steel or stainless-steel mills are available in a pressure impact resistant version up to 10 bar and are extremely suitable for the grinding of various food products. The air displacement that occurs due to the relatively high rotor speeds ensures that the product remains cool. As a result, Dinnissen centrifugal mills are ideally suited to grinding moist and greasy products. Examples include cocoa cake, filter cake, and cinnamon sticks.  

Various rotor and stator versions are available, such as pins, a turbo motor, or an additional paddle wheel. The capacity is - depending on the product - between 100 and 11,500 kg/hour and the desired final fineness can vary from 700 to 30 microns. Our centrifugal mills are single bearing, allowing the rotor to be moved completely out of the housing for inspection, maintenance, and cleaning.

How does a centrifugal mill work?

A centrifugal mill works based on centrifugal force and the rotor-stator principle. The product to be ground lands on the rotating rotor and is thrown out by the centrifugal force. Due to the force with which the product hits the stator combs, product reduction takes place. Through our years of experience, we can advise on the right settings and designs for each product and desired final fineness. An additional impeller, for example, can ensure that the grinding path is kept free when working with fatty and sticky products. The centrifugal mill is suitable for these types of products because the air displacement released by the relatively high rotor speeds cools the product. This keeps the moisture content in the product stable.

What customers say about us

Tailor-made solution for every problem

What charmed us most about Dinnissen was that they responded perfectly to our questions each time: they jumped right in and quickly came up with a tailor-made solution to each problem.

Perstorp

Jos Falvay- Project manager - Perstorp

Customized mixers

Dinnissen thought along with us from start to finish. For example, they used existing drawings for these new mixers to save us costs in the engineering phase.

ForFarmers

Pieter Gorter- Project Manager - ForFarmers

Drastically improved feed-quality

90% of our customers with laying hens have already switched to the new feed produced using the Pegasus® mixer and the Thermidor® system.

Egli Mühlen

Kurt Egli- Former manager - Egli Mühlen

Service on weekends

One day there was an important issue and one of Dinnissen's engineers immediately took action during the weekend. I have never seen other foreign partners do this.

APTe Japan

Mr. Kimio Aono- Founder - APTe Japan

World player in process technology

To realize production processes of the best quality, we work closely with Dinnissen: One of the strongest players in the world in process technology and hygienic design.

Nestle

Gerben Koopmans- Project Engineering Manager - Nestlé

No challenge is too big

At Dinnissen, they think in terms of challenges, not problems. They don't give up and keep going until there is a solution that satisfies all parties.

United Petfood

Martin Sonneveld- Production Director - United Petfood Waalwijk

Technicians, not salespeople

Dinnissen's representatives strive for the best solutions. They are engineers first and salespeople second.

Van Zutven

Frans van Zutven- Founder and Director - Van Zutven

High-quality vacuum coaters

We chose to work with Dinnissen because they supply high-quality vacuum coaters that fit exactly within our production lines.

Olam Group

Arnold Balledux- Global Technical Head Animal Feeds & Vice-president Animal Feed & Protein - Olam Agri

Six-fold increase of total production
