Hammer mills

Reliable, low-maintenance and an increased production capacity

Dinnissen has two types of hammer mill in its range: Hamex® and Dinnox. The Hamex® hammer mill has been used successfully for decades by manufacturers in various sectors. It is a reliable solution for grinding soft to medium-hard products such as grains, sugars and minerals. The Dinnox hammer mill is specifically designed for applications in sectors where hygiene is of great importance.

All hammer mills are designed as follows, for efficiency and reliability:

  • Proven robust construction: guaranteed long life.
  • Good accessibility: wear parts can be replaced quickly.
  • Variable direction of rotation to spread wear.
  • Production, quality control and testing: everything is done in-house.

Hamex® hammer mills can be equipped with frequency control, with which the rotor speed can be precisely tuned to the desired end result. With this you can easily switch between fine grinding or a coarse grinding structure. Another option is a specially developed airflow system, with which the passage of particles with the correct fineness is controlled quickly and efficiently. This increases the capacity and saves on energy consumption. The Hamex® Hammer Mill is also available with a semi-automatic and fully automatic screen change system, which are often chosen when a product is regularly changed.

How does it work?

See how cleverly placed hammers grind the product

Free-hanging percussion hammers swing around at high speed in the hammer mill. The resulting centrifugal force crushes the grinding material against the special breaking plates in the inside of the grinding chamber. The ground product then leaves the hammer mill through the exchangeable screen. Depending on the properties of the product to be ground, single hammers, double hammers or T-hammers are used.
