New Hamex Hammer Mill performs even better than expected

Dinnissen’s new hammer mill is extremely reliable and delivers 20% higher capacity in combination with improved product quality
Dinnissen Process Technology specializes in the development and production of process technologies for the feed, food, pharma and chemical industries. Dinnissen offers a wide range of crushers, hammer mills, roller mills, and knife mills for grinding, crushing and micronizing various ingredients. A year and a half ago, Dinnissen introduced its newest Hamex hammer mill to the market, which is equipped with increased screen surface, extra large grinding panels, and an automatic screen changer. This innovative combination delivers increased grinding capacity, less downtime, and greater flexibility. Dinnissen had the performance of its newest hammer mill measured over a period of one year, during which time 25,000 client batches were analysed. The results of this study made it clear that Dinnissen’s newest hammer mill performs even better than expected. The new Hamex hammer mill turns out to be extremely reliable and delivers 20% higher capacity in combination with a very homogeneous and product as well as reduced waste flows.

New screen panels, grinding panels, and hammers increase capacity by 20%

Dinnissen’s newest hammer mill is equipped with a completely new design for housing the screen panels inside the crushing chamber, thereby increasing the screening surface and automatically increasing screening capacity. The same applies to the grinding panels in the hammer mill, the surface of which is also increased thanks to an ingenious design, so that the capacity of the hammer mill is also increased. The way in which the hammers are fitted into the hammer mill actually increases the contact surface between the hammers and the grinding rotor, an innovation which also increases production capacity. The study performed (of carried out) by Dinnissen makes it clear that the new Hamex hammer mill actually has a 20% higher production capacity whereas power consumption has remained the same, a result which far exceeds the original expectations.

Zero malfunctions helps minimize downtime

The new Dinnissen hammer mill has a very robust design and operates at a maximum of 1800 RPM. As a result, the installation is much less sensitive to vibrations and malfunctions. The study carried out at various clients confirmed this and made it clear that the new Hamex hammer mill actually does minimize vibrations and noise. This is not only favourable for the operator but also has a positive impact on wear and tear and maintenance of the grinding installation. After one year of operation, the new Hamex hammer mill had not suffered from a single malfunction, a result which was again better than expected. So the study concluded that Dinnissen’s new hammer mill is extremely reliable and also requires less maintenance.

Significant reduction in maintenance as screens and hammers last three times as long
In its newest hammer mill, Dinnissen has improved the inflow of ingredients by integrating rock traps and magnets into the design. This innovation prevents damage to the screens from iron particles or hard objects and turns out to be very effective. In the course of a year, it became clear that the screens had never once suffered any damage, and the lifetime of the screens was extended by a factor of 300%. The new design of the hammers also had a positive impact on hammer wear, as the usable lifetime of the hammers was tripled. In the new Hamex hammer mill, the screen chamber holder is also equipped with an extra-wide and automatic screen opening. This facility creates extra opportunities for carrying out maintenance and replacing screens. As a result, the periods of downtime for the installation are much less frequent and also shorter. And finally, the automatic screen changer can remove and store the entire screen set within 40 seconds, carried out by the operated from his safe location, the operator room.

Less waste and a much better and more homogeneous end result

Dinnissen also had a study carried out into the quality and homogeneity of the ground products. The study made it clear that the new Hamex hammer mill not only delivers a more homogeneous end product per batch but that the homogeneousness of the end products remains much more consistent over time. The innovative design used by Dinnissen to integrate the hammers into the grinding rotor minimizes wear and tear and delivers more homogeneously ground products. The same holds true for the usable lifetime of the screen panels. Finally, Dinnissen improved the design of the screen holder with the aim of minimizing the loss of product to other areas of the production process. This minimizes waste and prevents damage to the screen panels.
