Roller Mills

Available on request

In a roller mill, the product is compressed between two counter-rotating rollers and reduced. A major advantage of this process is that the fines content (powders) remains limited compared to other grinding principles. A nice homogeneous grain size distribution can be achieved. It is possible to feed the product through one, two, or three roller pairs. The space between the rollers is hereby steplessly adjustable to an accuracy of 0.2 mm, as a result of which the product is continually downsized.

  • Low finesse proportion leaving a larger part of the product usable
  • Low heat generation
  • High capacity

Minimum finesse, maximum capacity

The roller mill is ideally suited for products that need to be downsized, but do not need to be ground into powder. Because we do everything in-house - from design and development to testing and improvement - we have been able to develop a roller mill that achieves a nice homogeneous grain size distribution time after time. The degree of product refinement can be determined by the distance between the two rollers, the profiles on the rollers, and the number of rollers used to downsize a product.  

Roller mills from Dinnissen are used successfully in different countries and various industries. Thanks to the low energy consumption and high capacity, large quantities of product can be processed in an environment-friendly and safe way.

  • Always homogeneous grain size distribution
  • Minimal energy consumption, maximum capacity
  • Robust construction ensures a long service life and low maintenance requirements
  • Safe and reliable: in-house production, quality control, and testing
  • You can test your products in advance for the desired result in our Dinnissen D-Innocenter.

Key features, options, and models

With a roller mill, various products can be crushed and ground. Product refinement occurs through a combination of compressive and shear forces. This principle is especially very suitable for products with a fibrous structure, such as cereals, oilseeds, and biomass. Because the heat generation is very low, it does not affect the products to be processed. The grain size of the product is determined by the profile of the roller and the space between the rollers. For ultrafine product pulverization, several pairs of rolls can be placed one above the other.

When using multiple pairs of rolls, the top two rolls are furthest apart, and the bottom two rolls are closest together. The further the product is in the production process, the finer it gets. A roller mill can reduce the product from medium-fine grains to ultra-fine grains, depending on the product and the desired result.

How does a roller mill work?

A roller mill uses two rollers that rotate against each other. The principle of the roller mill is that the rollers are close enough to each other so that no 'whole products' pass through, but far enough apart to ensure the product is not completely crushed. The distance between the two rollers can be determined per product and desired result. One of the two rollers is attached to the housing of the machine and the other is fixed by a suspension. By moving the roller on the suspension, the distance between the two rollers can be adjusted. Due to the low heat generation, it is also possible to grind moist and greasy products (e.g. raw materials for the food industry) without any problems.

What customers say about us

Fully automated sampling

We considered several machine developers, but the high quality of the Dinnissen machines and the competence and commitment of the employees were decisive for us.

Ausnutria

Arjan van Dijk- Project manager - Ausnutria

Mixing time of 60 seconds per batch

Previously, we had standard times in the mixing process of 14 - 15 minutes. With the Pegasus® mixer we achieve a mixing time of 60 seconds per batch.

Planta

Lothar Pixa- Director - Planta

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

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

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

Mixers have been running 30 years

Dinnissen machines may not be the cheapest in terms of purchase price, but in terms of value for money, there are none better. Our Dinnissen mixer has been running extremely reliably for 30 years.

VDV Group

Adwin van der Vorst- Directeur - VDV Group

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.
