Superior by Detail - Hammer Feed Mills without blower type BHOS

Hammer mills without blower type BHOS, when compared with a blower mill, deliver a significantly better milling performance than a blower hammer mill at the same power rating. The reason is that a BHOS mill dedicates the whole motor power to milling, without having to divert part of the power for the conveyance of grain/bruised grain.

The BHOS hammer grain mill assists in saving up to 40 % of energy costs in your milling and mixing plant.

The BHOS is available in two sizes with Mills without blower type BHOS. For efficient operation the mill is equipped with 24 or 32 hard metal hammers. A durability of over 5.000 t is possible.

Our reinforced round hole and wire mesh screens, too, have high durability.

The feed milling performance varies between 1.9 and 8.5 t/h, depending on screen size and grain consistency. Delivering a a high-quality feed with a minimal percentage of fine meal – an important contribution to animal health – is another advantage of this mill type.


Your advantages at a glance (hammer mill):
  • superior efficiency
  • robust rotor
  • minimum maintenance requirements
  • extreme durability
  • excellent milling performance
  • optimum feed consistency
  • minimum warming of the bruised grain
  • maximum screen surface
  • cost-efficient and energy-saving
  • quiet running
  • automatic mode for usage of off-peak power


We recommend to use an Autofilter (Aspiration) when a hammer mill without blower is installed. The fully-automatic Buschhoff autofilter performs the following tasks:

  1. It extracts the bruised grain out of the mill, resulting in a very low proportion of fine meal.
  2. It causes the bruised grain to cool down after the milling process. Ingredients are thereby preserved, and the build-up of condensate – with its negative aftereffects – is avoided.
  3. It causes low pressure inside the whole plant, which prevents the escape of dust.



Performance data valid for 4 mm round hole screen and 14 % humidity. Type of grain, humidity, structure of screen, residue all have a significant influence on feed milling performance.
