  • said mill is adapted to mill material including iron and non ferrous material, and said mill includes a separator in communication with said duct to take heavier material including ferrous material from the material passing along said duct.
  • said separator also separates ferrous from non ferrous material.
  • the mill and a cryogenic duct through which the material passes to be delivered to said inlet, a pipe to which a liquid is delivered under pressure, and a plurality of nozzles that receive the liquid from said pipe and provide for throttling of the liquid to a gas delivered to said duct to lower the temperature of the material passing therealong, temperature of the material being lowered to the extent that the material is brittle when delivered to said chamber.
  • said duct has an upstream end and a downstream end, said downstream end being connected to said inlet, with said pipe being located adjacent said downstream end.
  • said inlet includes an inlet duct, and a pipe located in said inlet duct and adapted to receive a liquid under pressure, and a plurality of nozzles providing for the flow of liquid from within the pipe located in said inlet duct and throttling the liquid to deliver gas to said inlet passage to thereby maintain the temperature of the material or lower the temperature of the material passing along said inlet passage.
  • said mill includes a door operatively associated with said inlet to open and close the inlet to control the flow of material to said chamber.
  • a mill to mill material in piece form by impact and a cryogenic device that lowers the temperature of said material to render it essentially brittle for delivery to said mill, said device including a downstream end through which the material is delivered to said mill, and at least one pipe extending through said downstream end and to which a liquid under pressure is delivered, and a plurality of nozzles receiving said liquid and delivering said liquids to said duct to lower the temperature of said material.
  • a method of processing a material provided in piece form including the steps of: lowering the temperature of the material to render the material substantially brittle to the extent that it will break or shatter if subjected to an impact; milling the material after the temperature thereof has been lowered, to subject the material to impact so that the material is reduced in size as a result of breaking and/or shattering; and separating the milled material into ferrous and non ferrous portions.
  • the milled material is separated into larger non ferrous portions, iron portions and lighter portions.
  • lowering of the temperature of the material is performed by subjecting a liquid to a phased change.
  • Figure 1 is a schematic part sectioned side elevation of an assembly including a mill, separator and cryogenic device
  • Figure 2 is a schematic part sectioned end elevation of the assembly of Figure 1;
  • Figure 3 is a schematic sectioned side elevation of the separator of the assembly of Figures 1 and 2;
  • Figure 4 is a schematic parts sectioned end elevation of the separator of Figure 3.
  • the apparatus and method described is with reference to a resilient material.
  • the methods and apparatus described are also applicable to food products, plastics and silicon as examples only.
  • an assembly 31 including a cryogenic device 32, a separator 10 and a mill 33.
  • the assembly 31 is intended to process tyres that have been reduced to pieces, such as tyres that have been shredded or milled. More broadly the assembly 31 is adapted to process resilient material.
  • Material to be processed is conveyed along a tunnel 35 of a duct 34.
  • the temperature of the material is lowered by delivering a liquid to pipes 37 and 38, with the liquid that escapes from the pipes 37 and 38 by means of nozzles 39 so as to be throttled and to be delivered to the tunnel 35 in a droplet and/or a gaseous form.
  • the material passes in the direction of the arrow 36 towards an outlet end 40 of the duct 34. Adjacent the outlet end 40 the pipes 38 are positioned together with their nozzles 39.
  • the material passing from the cryogenic device 32 to the mill 33 is at a temperature at which is most suitable to be used in the mill 30 so as to be reduced in size thereby by braking (shattering) due to its brittle nature.
  • the mill 33 includes an inlet duct 41 that extends to an inlet opening 42 via which the material to be milled is delivered to the milling chamber 43.
  • the mill 33 includes a hollow housing 44 providing the chamber 33.
  • the housing 44 also provides impact plates 45, each plate 45 providing an impact surface 46 against which the material to be milled impacts.
  • the material entering the chamber 33 is caused to impact against the surfaces 46 by means of a rotor 47 having a shaft 48 driven by means of an electric motor 49.
  • the motor 49 drives the rotor 47 in the direction of the arrow 50.
  • the rotor 47 includes impact members (hammers) 51 that engage the material and propel the material towards the surfaces 46. Milling is achieved by impact of the material with the members 51, the surfaces 46 and impact between the material circulating within the chamber 43.
  • Milled material is delivered to an outlet opening 52 from which there extends an outlet duct 53. Communicating with the interior chainage 54 of the duct 53 and just down stream of the opening 52 is the separator 10.
  • the separator 10 includes a drum 11 having a longitudinal axis 12.
  • the drum 11 has a radially outer surface 13 that is circular in transverse cross-section.
  • the surface 13 and drum 11 are cylindrical in configuration, however other configurations are contemplated, such as a frusto-conical configuration.
  • the surface 13 extends longitudinally of and angularly about the axis 12 so as to surround a chamber 14.
  • each convolution 16 Fixed to the drum 11 is an auger member 15 that extends longitudinally of and angularly about the axis 12 so as to provide a plurality of convolutions 16, each convolution 16 extending from the surface 13 away from the axis 12. Also, as best seen in Figure 1, each convolution is inclined to the surface 13 by an acute angle 17.
  • the drum 11 has end walls 18 that generally close the chamber 14.
  • a stationary shaft 19 Extending longitudinally into the chamber 14 is a stationary shaft 19.

  • the magnet 20 extends about the axis 12 by an angle 23.
  • the angle 23 preferably has a magnitude of between 180° and 270°, more preferably about 225°.
  • the magnet 20 extends from the horizontal transverse axis 24 through an angle of about 225° in a direction opposite the direction 27. Accordingly the majority of the magnet 20 is located below the horizontal axis 24.
  • the drum 11 is supported on the shaft 19 by bearings 24 so that the drum 11, with the auger member 15 fixed thereto, can rotate about the axis 12.
  • FIG. 1 Attached to one of the end walls 18 is a drive shaft 26 that is driven by means of a pulley 25, in turn driven by an electric motor not illustrated. Accordingly upon the shaft 26 being driven, the drum 11 is caused to rotate through 360° repeatedly about the axis 12. More particularly the drum 11 is rotated in the angular direction 27.
  • Figure 2 is a cross-section of the drum 11 along the line 2-2, and viewed in the direction 2.

  • the gas leaving the opening 52 and entering the interior 54 takes with it the lighter material such as cloth and string. Conveying of this material along the interior 54 to an outlet 59 is aided by means of an air conveyor 60 including apertures 61 and fins 62 that cause air jets to issue. The air jets aid in conveying the material away from the outlet opening 52.

  • the duct 41 provides a passage 68 via which the material passes, with at least one pipe 69 being provided to which a liquid is delivered and which is released to the passage 68 by nozzles 70 so that the liquid is in a droplet form and/or is delivered as a gas, maintaining the material at a desired temperature, that is a temperature which the material is essentially brittle and vulnerable to shattering when circulated in the chamber 43.
  • the liquid delivered to the pipes 37, 38 and 69 is nitrogen, CO 2 or Argon, as examples.
  • the liquid is delivered via the nozzles 39 and 20 in droplet (spray) form.
  • the valve 56 is a rotary valve that limits the escape of gas to the chute 57 while regulating the flow of the milled material to the chute 57.
