Definitions

  • I provide an installation in which a rotary impact crusher operates evenly, continuously and controllably in a manner which may be compared to that of a milling cutter. To this effect I do not let the scrap as customary just fall or glide into the crusher but feed the scrap continuously and with controllable speed into the operational range of the said impacting tools.
  • the installation according to my invention comprises a rotary impact crusher having its feed channel sidewise of its rotor, a charging device composed of an elongated open top box or trough leading into said channel and of a ram longitudinally displaceable therein by actuating means which push the same towards the feed channel continuously and at such regulated speed that the scrap is not overfed into the crusher and overloading and dangerous stresses therein are avoided.
  • FIG. 1 shows a longitudinal sectional view of an assembly embodying my invention
  • FIG. 2 a cross-sectional view taken along line II-Il of FIG. 1.
  • the assembly as shown is basically composed of a rotary impact crusher 1 and a charging device including an elongated open top feed trough or box 2.
  • the impact crusher includes a cylindrical housing 3 in which a rotor 4 turns at high speed with its shaft 5 driven by motor 22. Hammers 7 or other impacting tools are oscillatingly mounted on the circumference of said rotor by means of pivots 6.
  • the housing 3 is provided laterally of the rotor 4 with a feed channel 13 and below and opposite thereto with discharge openings 8 leading into a collecting chamher 9 which is open in its bottom and located above conveyor means 10.
  • the top portion of the housing 3 is constructed as a hood 11 which can be turned over axle 12 into the position shown in FIG. 1 in dotted lines to make the space and machine parts within the housing accessible from the outside.
  • a ram 15 is movably located.
  • a hydraulic drive 16 is adapted to forwardly displace the ram 15 continuously and with controllable speed from the shown position into close proximity of the feed channel 13. From the flat top face of ram 15 extends rearwardly a cover plate 17 which protects the space behind the ram when the same is forwardly moved.
  • the assembly operates as follows:
  • Metal scrap or other material to be crushed such as automobile bodies or the like is placed into the charging box or trough 2 while the ram 15 is in the shown rearward position.
  • the motor 22 is thereafter switched in to rotate the rotor 4 and the hydraulic drive 16 for ram 15 is operated.
  • the advancing ram 15 pushes the material continuously and with properly adjusted speed towards and through the channel 13 into the operational range of the rapidly revolving hammers or similar tools 7 which separate, similar to cutters of a milling machine, small pieces from the most advanced portion of the scrap. These pieces escape through the discharge openings 8 into the collecting chamber 9 and fall upon the conveyor 10.
  • the forward speed of ram 15 is selected with a view to the material operated upon and to the rotational speed of the rotor. If the crusher gets overloaded and overstressed at any moment, the forward speed of the ram is just reduced.
  • the rear bottom edge of the feed channel 13 may be formed 'by or provided with an exchangeable reinforcing ledge 18 to cooperate with the rotating impacting tools'7, both being made of high grade steel.
  • compressing means shown in FIG. 1 which compact any oversized scrap pushed forward by ram 15 to a size capable to pass through said feed channel 13.
  • This compressing means comprise a cheekplate 21 which in front of and above receiving end of the feed channel 13 is hinged thereto at 19 and is tiltable by hydraulic or other power means 20 from the shown position defining a funnel shaped feeding passage 14 into a position leading substantially straight into the feed channel 13. If the power of the ram 15 is insufiicient to press oversized scrap therethrough the cheekplate 21 is tilted downwardly by the operating means 20 thereby compacting oversized scrap to proper size. Thus continuity of feeding scrap into the crusher and a safe operation is assured.
  • An installation for breaking up scrap comprising in combination a rotary impact crusher including a rotor, impacting tools thereupon, and a casing; a feed channel leading into the casinglaterally of the rotor; an elongated open top charging trough leading into the feed channel; a ram displaceable in said trough; actuating means for said ram adapted to advance the same continuously at a 3 r 4 controllable speed; a swingable cheekplate mounted in References Cited 7 I front of the feed opening for tilting movement from an in- UNITED STATES PATENTS clined position defining a feeding funnel into a position leading substantially straight into the feed channel; and 2,669,924 2/1954 Welmer 241 '186 X means for actuating said cheekplate.
