Fast screen exchange grinding solution for medium-hard products

Maximize your milling efficiency with a solution that allows rapid screen changes without halting rotor operations, saving valuable production time while delivering consistent particle sizes from 150 microns to 3 mm.

Grinds and Sifts Solids with High Efficiency

The Hamex® Fast Screen Exchange Hammer Mill from Dinnissen BV is designed to revolutionize grinding and sifting operations in the food, pharmaceutical, pet food, feed, and chemical sectors. It stands out with its semi-automatic sifter change, allowing for swift turnover without halting the rotor, thereby minimizing downtime. The hammer mill achieves efficient processing of solids, powders, and granules, maintaining a consistent grind with a fineness between 150 microns and 3 mm, all while operating at a maximum speed of 1800 rpm. This feature, combined with lower energy consumption, makes it a sustainable choice for continuous production environments.

Incorporating large inspection hatches facilitates quick maintenance, reducing operational interruptions. The hammer mill is offered in robust construction, ensuring longevity and reliability under demanding conditions. Designed with flexibility in mind, it accommodates various hammer configurations—single, double, or T-hammers—based on material properties, enhancing its versatility across diverse applications like cereal grains flour, protein powders, nutraceutical supplements, and chemical catalysts.

The Hamex® Hammer Mills comply with rigorous in-house production and quality control standards, offering customizable options to fit specific production needs. This includes material finishes suitable for different industry requirements, ensuring compatibility with harsh chemicals and maintaining hygienic conditions for food and pharma sectors. Furthermore, Dinnissen’s engineering support ensures seamless integration into existing production lines, backed by a focus on innovation and continuous development.
