Hammer mills
Dinnissen hammer mills have been successfully used for decades to reduce, grind and sieve a variety of products. Hammer mills are designed to grind ingredients quickly and efficiently, to exactly the right composition and grain size. What makes Dinnissen hammer mills unique is that they not only grind perfectly, but they do so quietly, reliably and safely. Moreover, producers can benefit from smart innovations such as the automatic sieve changing system, which allows the sieve to be safely changed while the rotor is still turning.
Hammer mills from Dinnisssen are used particularly in the food, pet food and feed industries, but they are also used in whole other industries such as recycling and chemistry. Our hammer mills are sought after for their highly efficient grinding process, high reliability and safety and very low noise level. In general, soft to moderately hard materials can be processed, with = the fineness of grind normally in the range of 0.1 - 1 mm. Dinnissen hammer mills are available in various designs: Hamex® Hammer Mills with semi-automatic or fully automatic sieve changing system and Dinnox hammer mills, specifically designed for applications in sectors where hygiene is of great importance.
Hamex® Fully Automatic Hammer Mill
Available on requestThe Hamex® Fully Automatic Hammer Mill grinds soft to medium-hard products with fineness ranging from 150 microns to about 3 mm. With the built-in frequency control, the rotor speed can be accurately adjusted to the desired result. Switching between a fine or coarse grind is therefore easy and quick. With a maximum speed of 1800 rpm, the Hamex® Fully automatic Hammer Mill is an energy-efficient and quiet solution, without sacrificing grinding speed.
- A fully automatic sifter changing system
- A minimal noise level without negatively affecting the grinding speed
- Increased production capacity
Dinnox® Hammer Mills
Available on requestThanks to its one-sided bearing and sleek stainless-steel design, the Dinnox® Hammer Mill is ideally suited for industries in which hygiene is extremely important. The one-sided bearing ensures that the rotor can be driven completely out of the housing, for cleaning, inspection, changing the beating edges, and adjusting the hammer assignment. In addition, the sifting plates are easily accessible through doors and can be quickly changed, making this mill very suitable for an efficient production process. The Dinnox® Hammer Mill enables fineness ranges between 150 microns and 3 mm.
- Easy to clean thanks to one-sided bearing and stainless-steel design
- Variable rotor speed
- Testing possibilities in Dinnissen test facility
Hamex® Semi Automatic Hammer Mill
Available on requestThe Hamex® Semi-automatic Hammer Mill grinds soft to medium-hard products with a fineness from 150 microns to about 3 mm. With a maximum speed of 1800 rpm, the Hamex® Semi-automatic Hammer Mill is an energy-efficient and quiet solution. The RPM is lower than the Hamex® Hammer Mill, but because the tip speed of the hammers is not reduced, you can achieve a similar grind at lower energy consumption.
- A semi-automatic sifter changing system
- Minimal noise levels, while maximizing the grinding speed
- Good accessibility allows worn parts to be replaced quickly
Hamex® Hammer Mills
Available on requestHamex® Hammer Mills are designed for the grinding of soft to medium-hard products with a fineness from 150 microns to about 3 mm. In the hammer mill, freely suspended hammers swing around at high speed in the grinding chamber. Depending on the properties of the product to be ground, single hammers, double hammers or T-hammers are used.
- Proven robust construction: long life and low maintenance
- Variable direction of rotation to spread wear
- Optimized over decades for efficiency, capacity, and uptime
Grinding
To create powders, pellets or granulates, a grinder is often used to reduce the coarse product -the raw material- to the desired size. But one grinder is not the other. Which solution is the best choice for your production process depends on the product to be reduced, the desired final fineness and the line in which the grinder is to be integrated. With more than 70 years of experience as a system integrator, Dinnissen is the specialist in advising on the best solutions. In addition to Centrifugal Mills, we provide Roller Mills, Crushers, Shredders and Pulpers.
Dinnissen has a range of grinders tailored to the product to be ground and the desired final fineness. For very fine grinding, a Centrifugal Mill can be chosen. Depending on the product, a final fineness between 700 and 30 microns can be achieved. When you do want to reduce your product, but do not want a powdered form, the Roller Mill can be a good choice. This mill provides a nice uniform particle size without grinding the product into powder.
For a coarser final fineness, a Crusher can be used. A Crusher reduces large, hard materials and is also suitable for elastic and tough materials. For soft, tough products, a shredder can be used. Here, the product is reduced in size by means of knives. One step further than the Shredder, is the Pulper. This industrial blender finishes products such as vegetables or fruits, using fast-rotating blades.
Centrifugal Mill
Available on requestIn 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
Roller Mills
Available on requestIn 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
Shredder
Available on requestDinnissen shredders were developed for the safe and quick shredding of various products in both the food and feed industry and in other industries such as the recycling industry. The shredders contain one or two rotating rotors with blades attached. The distance between the blades and the housing is adjustable and determines the product fineness.
- Uniform product reduction
- Adjustable cutting speed
- Easily changeable knives
Pulper
Available on requestDinnissen has developed pulpers for fast and safe blending of, among other things, fresh vegetables, and fruit. In addition, these pulpers are increasingly being used to pulverize alternative raw materials such as algae, insects, and other types of protein substitutes. Easy to fill, empty and clean, the ergonomically designed blender meets the strictest food safety standards.
- Meets the strictest hygiene requirements through simple and thorough cleaning
- High capacity
- Homogeneous pulping
Breaker
Available on requestA breaker reduces products according to the rotor/stator principle; with ridges on a central shaft in combination with stator combs mounted in the housing. The low rotational speed makes it possible to achieve high capacities at low energy consumption. From 100 kg to 80 tons per hour, with finenesses from 150 microns to 10 mm.
- 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
