Definitions

  • the present invention relates to a Raymond shredder for crushing ore.
  • the existing Raymond pulverizer in the process of crushing the ore powder, mainly drives the central flower stand directly connected thereto with the motor located under the chassis of the pulverizer, and rotates the roller suspended around the center flower stand. Under the action of the centrifugal force, the centrifugal force generated by the rotation of the roller pushes the crushing force to the crushing wall under the suspension, thereby crushing the ore that is caught between the roller and the crushing wall into a powder.
  • the electric motor 1 of the current Raymond shredder is mounted below the chassis 5 and penetrates from the center of the chassis 5, and is fixedly coupled to the center of the center flower stand 2 above the chassis 5,
  • a plurality of rocker arms 6 are suspended and mounted around the center flower stand 2, and the upper end of the rocker arm 6 is mounted in an active state around the center flower stand 2.
  • the lower end of the rocker arm 6 is suspended from the movable roller 3, and the roller 3 is integrated with the center flower stand 2, and is surrounded by a circled wall ring at the upper surface of the chassis 5.
  • the center flower stand 2 When the motor 1 under the chassis 5 is started, the center flower stand 2 is rotated rapidly, and the center flower stand 2 rotates to drive the rocker arm 6 which is suspended around the center flower stand 2 and the roller which is suspended and connected at the lower end thereof. 3. Following the synchronous rotation of the periphery of the center flower stand 2, the roller 3 is pushed toward the inner surface of the mill wall 4 in the suspension of the rocker arm 6 under the centrifugal force of the rapid rotation. Thereby, the ore sandwiched between the roller 3 and the mill wall 4 is subjected to crushing and crushing.
  • the rocker arm 6 (FIG. 1) is removed, and the roller 3 is directly installed in the peripheral body of the center flower stand 2, A plurality of rollers located around the center of the flower stand 2 are movable around the center of the flower stand 2, and each of them can be re-sliding in a radial direction among the respective movable structures.
  • the roller 3 When encountering a pile of ore, the roller 3 will slide along the center of the radial center flower stand 2 in the structure without the damage of the lever force of the rocker arm 6 and twist the center flower stand 2. Therefore, when the crushed ore is crushed between the grinding wall and the roller 3, The safety of the Raymond shredder is better guaranteed.
  • Figure 1 is a schematic view showing the structure of the Raymond pulverizer before the improvement.
  • FIG. 2 is a schematic view showing the structure of the improved Raymond pulverizer.
  • the motor 1 is disposed under the chassis of the Raymond shredder, and the main shaft of the motor 1 is fixedly coupled to the center of the center flower stand 2 above the chassis 5 via the center of the chassis 5, at the center of the flower stand 2
  • the periphery is provided with a plurality of rollers 3 which are free to slide along the radial direction.
  • a circular milled wall is provided on the periphery of the assembly, above the chassis 5, a circular milled wall is provided.
  • the motor 1 drives the central flower stand 2 fixedly mounted at the upper end thereof to rotate rapidly around the central axis of the motor 1.
  • the rapidly rotating central flower stand 2 will be generated synchronously with the speed of the rotation.
  • Large centrifugal force Under the push of this centrifugal force, the roller 3 installed around the center of the flower stand 2 is pressed against the peripheral mill wall 4 by the centrifugal force, and the roller 3 is driven by the center flower stand 2 along the inner surface of the mill wall 4. Rolling, and rolling in synchronous rolling, crushing the ore between the roller 3 and the mill wall 4, the ore is finally in a powder state during repeated rolling.

Abstract

Dans une chambre interne d'une paroi roulante ronde (4), un rouleau (3) roulant sur une surface interne de la paroi roulante (4) pour broyer et pulvériser un minerai est directement monté sur une périphérie d'une étagère de fleurs centrale (2). Dans la présente invention, un bras oscillant d'un rouleau suspendu sur la périphérie de l'étage de fleurs du pulvérisateur Raymond est supprimé, éliminant ainsi l'origine de la distorsion et de la déformation de l'étagère de fleurs, et supprimant le bruit généré par la rotation du bras oscillant du bras suspendu en raison d'une étagère de fleurs non lisse dans un procédé le pulvérisateur concasse le noyau. De plus, pour le pulvérisateur présentant un châssis avec un diamètre identique, parce qu'un diamètre de l'étagère de fleurs pour le montage du rouleau est accru, une périphérie de l'étagère de fleurs est accrue simultanément, et le nombre de rouleaux montés peut être accru ; par conséquent, la quantité de minerai pulvérisé est également accrue au même moment.
