FOR SALE
  Tyronics 500/80 Rotary Shredder
 
Universal Rotary Shredder with two high tensile shafts, each independently driven via heavy duty, double helically geared 4 shaft gear boxes. Diesel powered unit, easily converted to twin electric drives if desired. 18 cutters in total of 5 teeth each, very comprehensive hard facing with hardened spacers between each.
 
 
  • Initially designed for primary shredding of tyres including all passenger car sizes, 4 x 4, up to light truck sizes incl. 8.25 x 16
  • Cutter speed variable to max. of around 30 RPM depending on engine speed and transmission gears selected
  • All controls to clutch, throttle, and other operating systems are via electro pneumatic switch gear, all are set up to react to “E” stop stations. Any emergency stop will automatically “kill” all rotating components, including conveyors and main driveline.
  • Fully operational system comes complete with all 3 conveyors as shown, including the external motorized slewing unit.
    Spares and a full set of drawings will be included as a package.
  Design features & performance
 
 
  • Self contained 120 hp (47kw) diesel power, driving via a manual transmission with 3 forward gears (2 used for high & low cutting), and a reversing gear. A multi shaft gear box, each giving around 72:1 reduction, drives each shaft via cogged belts. As an option, drives may be fitted with electric motors if desired. (22 kw each)
  • Unique split chamber as depicted, enables rapid removal of the main shredder shafts for service. These are installed in fully assembled condition, pre tensioned with couplings, bearings, oil seals, cutters and spacers etc. ready to run.
  • In top gear at 1800 motor RPM, the machine will handle 2,200 car tires per hour (around 20 tons) The chamber is fed via an inclined conveyor, where the tyres are seized by a train of 3 rollers per side. These rollers are pneumatically forced in on tracks, thus driving the tyres vertically through the cutter array, no hesitation whatsoever.
  • The cutters are our own design of Bisalloy 360, all the edges are prepped and hard faced at 60-62R.C. as an average. Est. around 600,000 tires lifespan before servicing easily achieved. See the specifications for full details.
  Conveyor system as fitted
 
 
  • All conveyors depicted are part of the package. Above is shown the out feed unit. The whole unit is a traversing type, motorized ground wheels enabling the loading of various transporters from end to end, without constantly moving the vehicle. Sensors are fitted to preset the arc of sweep required. This conveyor is fed via the unit under the chamber, which is reversible to enable product to be sent to an alternate destination. The under chamber, and main out feed conveyors are interlinked at the control station, both responding to the emergency stop circuit.
  • Feeding the shredder is a fixed (adjustable) inclined conveyor with a feeding speed of 30 metres per minute. This enables tyres to be loaded quickly, and with a width of 1300mm, car tyres are loaded in a staggered pattern ensuring swift and constant shredding.
  • All conveyors are powered by Eurotherm S.E.W. motor/gearboxes, with final drive via chains & sprockets, to enable ratio adjustment.
  • All controls located on a master console, with remote “E” stops
  View of in feed roller train, guards removed for clarity.
 

Note tapered entry of roller train, gear drives, and the track mounting with pneumatic cylinders for tractive feed effect.

View R12 reo bars staggered around each roller to ensure maximum grip & drive is transmitted to tyres entering the cutting chamber. Cutter array is also visible, 18 in total of 80mm thickness, cutting overlap is 14mm. Opposed cutter clearance is .1mm (.004”) to ensure clean shearing of tyres.

  Tyronics 500/80 Rotary Shredder
Specifications:
  Cutting Chamber:
 
  • Shafts: 8” (203mm) hexagonal. Forged 4140, machined & ground to specs.
  • Cutters: 360 Bisalloy, profiled, 12mm x 45deg. weld prep all round, capped with 309 Stainless weld, 2 overlapping runs & 1 capping run of 650G hard facing. All cutters wash ground to a tolerance of .03mm. Around 62 R.C.
  • Spacers between bearings & chamber, for seal faces, between cutters, and all end caps: All are 4140, fully gas nitrided & ground to specs.
  • Bearings: SKF 23232 CE4 C3 spherical roller type. 4 in total.
  • Chamber: All boiler plate fabrication, bearing housings from 8” thick solid. All weldments are 8mm fillets, all gussets fully welded. Chamber halves are fully machined top & bottom, bearing bores are done in pairs, “A” end bored to shoulders (fixed end), opposite “B” end are floated bearings.
  • Studs: Clamping upper & lower chamber are custom made 4140 H.T.
  • In feed rollers: Are gear driven at either end, each successive roller is 50mm closer to centre than previous, giving a funnel effect. Each set has pneumatic cylinders at each end for positive drive (50mm travel for either set) The rollers are heavy wall tube of 6.75” dia. (170mm) around each is 8 equally spaced pieces of 12mm deformed reo bar for traction.
  Transmission:
 
  • Diesel; Perkins 6/354 dot 4, injector pump updated to stationary specs. Coupled to a New Process transmission, via a 14” single dry plate clutch. Clutch is controlled using a flow controlled pneumatic cylinder. From the rear of the NP gear box, drive is through a Fenner A90 tireflex coupling to the main shaft. This shaft of 60mm dia. is carried on 3, UCF 311 bearings, and drives the “B” end reverse gearbox via a H300 timing belt. From the main shaft, under the structure, the power is transmitted across to an aux. shaft for the “A” end via 4 SPBX cogged belts. This shaft then drives the “A” end gear box through a H300 timing belt. Ratios selected ensure there is a differential in shaft speeds i.e. if one shaft in chamber has completed 24 revs, the other will have done 23 revs. This ensures we maintain a constant changeable cutting action, utilizing the entire cutting edge, not just a localized shearing point.
