Hammer Mills

The principle of the mills is to reduce the dimensions of incoming materials to a particle size sought after by the mechanical action of hammers coming into contact with the material. 

The material thus reduced is conveyed through calibrated screens until the next step of the transformation process.

PROMILL has a wide range of hammer mills to offer solutions to all industries and customers.

The design of the PROMILL hammer mills guarantees the required quality and capacity while optimizing the durability of the components.

WCR wet hammer mill

This type of grinder is mainly used for the wood industry and for the grinding of plant materials in the post-drying phase. 

The moisture content in the material to be crushed is quite high and therefore requires a better grinding torque and an increased strength of the components.

Different powers of motorization are available according to the capacities to be reached.

Main features

  • Strong build body
  • Strong built rotor
  • Special reinforced hammers
  • High production capacity
  • Low energy consumption

Fields of application

  • Grinding of wood
  • Grinding of DDGS
  • Grinding of cereals

Hammer mill refiner type BNA

The BNA mill is used to carry out the final step of reduction of the particles sizes also called "refining". The incoming material was previously dried to contain only 8-12% moisture.

The desired particle size is obtained at the outlet of the sizing screens. 

Different crusher / refiner sizes are available depending on the materials and production capacities to be produced. Different powers of motorization are available according to the capacities to be reached.

Main features

  • Heavy build body
  • High capacity low energy consumption
  • Flexibility to process many wood species
  • Several types of hammers available
  • Several screens sizes available

Fields of application

  • Grinding of wood
  • Grinding of alfalfa
  • Grinding of DDGS
  • Grinding of cereal products

ROTOMILL Straw Chopper

This equipment has been designed for the pre-grinding of straws used in various applications such as animal feed, litter, biofuels, boiler feed. 

Depending on the destination of the finished product the ROTOMILL can be accompanied by a refiner and a pelleting press.

Main features

  • Heavy duty equipment
  • Capable to process all kinds of straw
  • Safety cover
  • Inlet filtering device

Fields of application

  • Grinding of straw to produce litter
  • Grinding of straw to produce animal feed
  • Grinding of straw to produce biomass energy
  • Grinding of straw to produce biofuels

Bulk grinding Mill type BNE

Different uses are made of rendering products. 

BNE grinders have been developed to handle all types of complex materials requiring high abrasion resistance.

Main features

  • Strong build body
  • Strong built rotor
  • Special reinforced hammers
  • Special reinforced counter hammers

Fields of application

  • Grinding for rendering of animal products
