Hammer Mills GHM

100 years of experience and innovation have led to the development of a wide range of high-efficiency hammer mills. The hammer mills GHM series are equipped with adjustable breaker plates which can be positioned vertically according to the direction of rotation. Placing the breaker plates at two different positions create an asymmetric formed grinding chamber. This results in a remarkable increase in impact forces thus less wear on the screens and a smooth flow of product through the grinding chamber. In combination with an Ottevanger feeder fully automatic load control is possible on these hammer mills.

The Hammer mill GHM series features a solid all-welded construction and has a number of benefits, which are mentioned below.


  • Designed for dual direction of rotation
  • Electro-pneumatic operated product guide valve
  • Adjustable breaker plates
  • Built on heavy base frame with shock absorbers
  • Precisely balanced rotor guarantees a long service life
  • 6 rows of hammers
  • Suitable for frequency control

Special execution

  • 8 rows of hammers for aquatic feed and pet food
  • Automatic feeder (optionally frequency controlled)
  • ATEX22 certified components

The new line of the Hammer Mill GHM is the special High Efficiency Line which has a very hygenic design and is focussed on high performance but also lower energy consumption.
