Impact mill for grain feed (priority: 1/6/1968 - Bulgaria - No. 10114)

The invention relates to a beater mill for grain feed, in which the feed rotor is constructed so that it directs the grains at high speed against the impact body of the working rotor. The hammer mill has Knife and counter-thrust body with special profile and shape and works without a sieve »

Beater mills for comminuting grain feed by means of a rotor are known, which are movable or non-moving attached impact body (hammer, shovels, etc.) to ° point. The ssu processing seeds fall against the rotor free or led by a sloping gutter «and if they being hit by the shellfish «they fly against the contact surface (corrugated plate or udder) «the movable or is immobile, so that the grains on impact against the punch body ede * impact fl & 2h§ are reduced.

SAO ORIGINAL.

After the chopping, the smaller pieces fall through the sieve, the larger ones are again τοη the impact body or shovels. According to this working principle, an uneven production is achieved.

The structure of such a Kotortrommol is korn = The individual parts wear out unevenly, so balancing is difficult.

The invention relates in particular to the improved work of the rotor drum, which is equipped with special toothed masses adapted to the seed size zerkiainerndan seeds are increased, the impact on the knife becomes more violent, and the damage. better grinding »The unwanted flour fraction is reduced by up to 20 % in this case · Dia beater mill works without

An exemplary embodiment according to the invention Wirti inclined to the drawing shown, wobai:

Fig. 1 a cross section through the hammer mill,

Äbfa * 2 the fixation of the Messar 6 on the Drum and

Fig. 3 the gag impact (impact) body according to pos. 4 is _o

The hammer mill consists of a body I, Vor « sehub (feed rotor 2; Hagler 3; toothed counter-thrust body 4; Working rotor S and serrated knives 6 »

SADORrQlNAL

The feed rotor 2 is placed directly on the shaft of a separate electric motor at 3,000 rpm. On the circumference of the feed rotor there are profiled feed displays » finely attached.

The working rotor 5 is placed directly on the shaft of another electric motor, also at 3,000 rpm. Grooves that accommodate the working knife 6 are incorporated into the circumference of the working rotor. The working knives are third-tooth teeth with a high pitch, which ensure the desired size reduction and are set by the intermediate plates 7. For the correct feed of the seeds on the Work knife and the bowlers 3 is mounted _o The controller provides a ,, the entire hopper width of the impact mill receiving steel plate which its location others can be achieved by adjustment groove /

The third-tooth counter-impact bodies 4 are attached to the body of the beater mill. They are in order to recruit or replace worn teeth around their axis "" bar.

The seed comes from the feed rotor, which rotates at high speed and in time to the working rotor is arranged with the toothed knives. The seeds will Ton accelerated the blades of the feed rotor and hurled them directly against the third-toothed knives of the working rotor Upon impact, the grains are crushed, whereby a small percentage of the flour fraction is formed. Thanks to the thirds The surface before the knife and the counter-attack body becomes the desired Zex reduction effect achieved The hammer mill works without f35eb.

The Inerfcions beater mill has a simplified structure without sieve, bearings and belts. The organs of work are easily accessible and easily interchangeable

BATH ORIGINAL

The service life of the work hanuaer is essential bigger than the existing hammer. The profiled knife 6 has a larger working area than that of the best » rotating hammers, which also results in greater efficiency.
