Definitions

  • this second rotor and of the blades is that the inerts are received from the top, are guided along a circular trajectory and thrown against the face of the hammers of the mill, not vertically, but in a direction almost normal to the face of the hammer (avoiding the rise of tangential stresses which produce wear). In such a way, the inerts are accelerated and acquire a speed equal to the peripheral speed of the blades.
  • the two eccentrics for wear compensation adjustment of the accelerating blades come into play.
  • These wear compensation registers divert and direct the inerts coming from the accelerating blades against the hammers which rotate along a direction opposite that of the blades they are integral with. This deviation causes the inerts to hit the hammer under almost normal conditions.
  • the prototype of the equipment, according to this invention turns out to be capable of treating micronized materials (and, hence, particle sizes defined as quaternary) reaching a peripheral speed in excess of 110 m/sec.
  • the transmissions of the motion between main and secondary axes occur through pulleys and drive toothed belts capable of taking care of the huge loads involved and to limit the acoustic impact of the device.
  • Each one of the eccentrics (3) provided with two holes in the shape of buttonholes for adjustments, is bolted to the housing of the structure by means of two bolts (9) with a clamping system.
  • the entire structure is built with materials with high wear resistance.
  • the dimensions mentioned above refer to tertiary mills and are slightly modified in the case of secondary mills or of those defined as quaternary.
  • the industrial application that distinguishes this invention is represented by the installations for the production of cements, mortars, sands, fillers, micronized materials, etc....i.e. all those applications that require the use of material crushing equipment

Abstract

Concasseur à marteaux à impact total pour le broyage, à utiliser dans l'industrie du bâtiment et en agriculture, qui comprend un rotor primaire doté de marteaux et un rotor secondaire comprenant autant de lames qu'il y a de marteaux, ainsi qu'une trémie d'alimentation d'où le matériau à traiter est convoyé à l'intérieur de la limite extérieure maximale tracée par les lames du rotor secondaire. Ledit matériau, une fois saisi par une lame, est forcé de couvrir une trajectoire circulaire et est jeté à une vitesse accrue à l'intérieur de la chambre de broyage dotée de plaques plates (2) capables de diriger le matériau à traiter à l'intérieur de la limite maximale du rotor secondaire et sur toute la longueur des lames (4) soudées directement au tube cylindrique (7) ou fixé par une queue-d'aronde à l'intérieur de cannelures sur un tube en acier cylindrique (7) d'un seul tenant avec le rotor secondaire, qui permet également une protection contre l'usure. Une came métallique (3) compense l'usure des lames (4) et dévie et dirige ultérieurement, par le biais d'un mouvement translationnel d'approche vers la pointe de la lame, une fois que sa distance et l'inclinaison par rapport à la pointe de la lame ont été réglées, et qui est fixée au moyen de ses boulons de fixation (9), le matériau à lancer dans une direction perpendiculaire à la face du marteau (5) en évitant ainsi le rejet dudit matériau à cause des grandes vitesses de rotation impliquées.
