Roller mills, plansifters and purifiers at the heart of the mill
Grinding Units
HK roller mills with precision-ground rolls, square plansifters, semolina purifiers, bran finishers, impact detachers and hammer mills convert cleaned grain into flour, semolina and bran with consistent extraction. Pneumatic fans and super sonic filters keep the process dust-free and efficient.

How it works
Working principle
Grinding turns cleaned, conditioned grain into flour, semolina and bran in several passes through roller mills and plansifters.
- 1A feed roll meters the stock into an even curtain across the full roll length.
- 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.
- 3The ground stock falls to the outlet and is conveyed to the plansifter, which separates it into fractions for the next pass.

HKKE
Square Plansifter
The square plansifter separates ground stock into flour, semolina and bran fractions with stacked square sieve decks in a gyrating motion.

HKIS
Semolina Purifier
The semolina purifier combines sieving with a rising air current to grade semolina by size and purity and to remove bran particles.

HKKF
Bran Finisher
The bran finisher strips residual flour from the bran with rotating beaters inside a perforated screen, raising extraction at the tail of the mill.

HKIK
Impact Detacher
The impact detacher breaks up flakes leaving the reduction rolls with a high-speed pinned rotor so the stock can be sifted efficiently.

HKVE
Vibro Sifter
The vibro sifter is a compact vibrating control sifter that checks flour, semolina and bran before packing and removes foreign matter and lumps.

HKVB
Vibro Feeder
The vibro feeder meters product evenly onto a sieve or into a machine with a vibrating tray, preventing surges and keeping operation stable.

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

HKUK
Blower Hammer Mill
The blower hammer mill combines hammer grinding with an integrated blower that conveys the product pneumatically, saving a separate fan and conveyor.

HKPF
Pneumatic Fan
The pneumatic fan is the high-pressure centrifugal fan that drives the mill's pneumatic conveying system, carrying stock from the roller mills to the sifters.

HKSF
Super Sonic Filter
The super sonic filter separates conveyed product from the air and cleans its bags with compressed-air pulses, keeping the line continuous and dust-free.
