Hamex® Automatic Screen Exchange Hammer Mill

Available on request

The Hamex® Automatic Screen Exchange 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® Automatic Screen Exchange 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

Fully automatic sifter changing system and frequency control

The Hamex® Automatic Screen Exchange Hammer Mill makes it possible to change sifters without the intervention of an operator, while the rotor continues to run. This results in saving ten minutes as well as a reduction in the need for manpower. In addition, the Hamex® Automatic Screen Exchange Hammer Mill can be equipped with frequency control, which allows the rotor speed to be precisely tuned to the desired result.  

Hamex® Hammer Mills are the result of years of innovation and continuous development to make them even more efficient, productive, reliable, energy-efficient, (explosion) safe and quiet.

All Hamex® Hammer Mills are designed as follows:

  • Long service life thanks to tried and tested robust construction
  • Good accessibility: worn parts can be replaced quickly
  • Variable direction of rotation to spread wear
  • Production, quality control, and testing are all carried out in-house
  • Decades of optimization for efficiency, capacity, and uptime

Key features, options, and models

The Hamex® Automatic Screen Exchange Hammer Mill rotates at a speed of up to 1800 rpm. However, the tip speed of the hammers has remained the same, allowing you to achieve a similar grind at lower energy consumption. The Hamex® Automatic Screen Exchange Hammer Mill can be equipped with frequency control, which allows the rotor speed to be tuned to the desired result. This allows easy switching between a fine grind and a coarser grind structure. Another option is a specially developed airflow system. This regulates the throughput of particles with the correct fineness quickly and efficiently. In addition, the machine can be equipped with a stone collector and magnet that separate iron particles and hard objects from the product to be processed. This helps to prevent contamination of the product and damage to the sifting.

How does a Hamex® Automatic Screen Exchange Hammer Mill work?

In the hammer mill, freely suspended hammers swing around at high speed. This creates centrifugal force which crushes the grinding material against the crushing plates inside the grinding chamber. These shredders have been specially developed to crush the material as efficiently as possible. The crushed product then leaves the hammer mill through the replaceable sifter. Depending on the properties of the product to be ground, single hammers, double hammers, or T-hammers are used.
