Dry Milling – Hammer Mills

Dry Milling – Hammer Mills

Hammer mills are designed to crush brittle materials and break down conglomerates.  The Hammer mill HM 2х2 is laboratory-class equipment designed to crush small batches of material with output up to 100 kg/hour.

The operational principle of a hammer mill is based on impact on material particles.



Material particles are broken down: 
  • When a hammer falls on them;
  • When they impact the liner and walls of the housing;
  • When the particles collide with each other.


  • The ability to obtain various crushed product
    grain sizes by:
  1. Installing grates with openings of various shapes and sizes from 0.8 mm;
  2. Selecting the number and shape of the hammers; changing the HM 2х2 rotor rpm;
  3. Installing a smooth or ribbed liner in the cover of the HM 2х2;
  • Free suspension of the hammers on the rotor axes reduces the probability of mill breakage when an unbreakable object falls into the working chamber;
  • The size and configuration of the loading funnel have been selected for safe maintenance and to prevent ejection of material particles during operation;
  • The hinged bolts on the cover of the HM 2х2 provide quick access to the crushing chamber for inspection
    and replacement of hammers and grates, and cleaning
    of the chamber;
  • Ability to connect to the dust collector to:
  1. Lower the temperature in the crushing chamber
  2. Lower the content of the dust fraction in the product;
  3. Separate material into three fractions: sedimented into the crusher receiving container, cyclone and bag filter.
