Hammer Mill

The hammer mill grinds grain and feed ingredients with swinging hammers against a screen, with fineness set by the screen aperture.

HKCD

The hammer mill works by impact from free-swinging hammers on a high-speed rotor. Product is broken between the hammers and the grinding chamber, and particles fine enough pass through the screen apertures and leave the machine.

Fineness is set simply by changing the screen, so one machine covers everything from coarse cracking to fine grinding. Hammers can be turned so that all four corners are used.

Capacity, hammer count and motor rating are given in the model table. The housing cover opens so screens and hammers can be changed quickly.

Key features

  • Free-swinging hammers usable on all four corners
  • Dynamically balanced rotor
  • Hinged housing for quick screen and hammer changes
  • Wear-resistant grinding chamber liner

Applications

How it works

Working principle

Grinding turns cleaned, conditioned grain into flour, semolina and bran in several passes through roller mills and plansifters.

  1. 1A feed roll meters the stock into an even curtain across the full roll length.
  2. 2Two counter-rotating fluted rolls, one faster than the other, shear and crush the grain in the nip; pneumatic engagement lifts the rolls apart when the feed stops.
  3. 3The ground stock falls to the outlet and is conveyed to the plansifter, which separates it into fractions for the next pass.
