Definitions

  • the present invention relates to a mobile aggregate processing plant having a crusher on a mobile chassis.
  • Mobile aggregate processing plants are well known in the art, and generally comprise a mobile chassis with aggregate handling equipment such as a crusher and screen, mounted on a chassis.
  • the processing plant includes a feed hopper or the like to help direct material into the crusher, and one or more conveyors able to transfer material processed by the crusher to a nearby location or other unit.
  • An example of such a processing plant is shown in EP2883624A1 , WO2004/085071A1 and US2007/158479A1 .
  • Mobile aggregate processing plants are frequently used in quarries, building sites and the like, for crushing or comminuting larger material such as quarried stone, or waste materials such as rubble from demolished buildings.
  • Jaw crushers are particularly suitable for, rough crushing at quarries, or crushing of waste or construction materials. According to the operating principle of a typical jaw crusher, crushing takes place against or between two jaws, typically one being fixed and one being a moving jaw.
  • the material to be crushed is fed with an excavator or wheel loader to a feed hopper, from where the material falls into the throat of the jaw crusher, or a feeder transfers the rock material towards the jaw crusher.
  • the material to be crushed may also be recyclable material, such as concrete, bricks, or asphalt.
  • Mobile aggregate processing plants are typically large and heavy. For example, they can have a height of more than 2 metres, typically at least 3 metres, 4 metres or more, with a length of several metres, and a weight of several tens of tonnes.
  • a processing plant is manufactured, and then transported to each and every location where they are used.
  • the mobile chassis provides some local or on site mobility, but it is not intended to be suitable for delivery of the processing plant, and for travelling on roads between locations or sites.
  • the shapes of many mobile aggregate processing plants are typically 'bespoke', i.e. not 'conventional', and they therefore require non-standard or exceptional transport costs, in particular non-standard shipping costs.
  • non-standard or exceptional transport costs in particular non-standard shipping costs.
  • the Europe-US shipping costs are typically over $10,000, or even over $15,000.
  • Subsequent exceptional road transportation to a final location or site adds to the final cost to a purchaser of the processing plant.
  • a mobile aggregate processing plant comprising a mobile chassis and a crusher mounted on the mobile chassis via a mounting, the mounting including a plurality of height extenders able to move the crusher between a transport configuration and an operating configuration relative to the chassis, and therefore able to alter the overall height of the mobile aggregate processing plant between a transport configuration and an operating configuration.
  • the overall height of the mobile aggregate processing plant can be lowered to achieve a suitable transport configuration, and raised to an operating configuration where there is no height restriction.
  • the overall height of the mobile aggregate processing plant is considered relative to the surface, usually the ground surface, on which the chassis rests.
  • the crusher may be of any size, shape, design or arrangement, generally having one or more jaws or arms, an upper portion adapted to receive material, typically from a feed hopper or the like, and one or more discharge outlets, typically starting at a low or lower portion, optionally at the bottom of the crusher, and able to allow crushed material to pass out away from the crusher, typically on to one or more conveyor belts or the like.
  • space is provided beyond, typically below, a discharge outlet of the crusher, to allow discharged material to move away or fall away from the crusher and prevent blockages at the discharge outlet.
  • Different crushers will typically have different discharge space parameters.
  • One parameter can be a vertical gap or height from the discharge outlet. Any space provided beyond or below a discharge outlet is not required when the mobile aggregate processing plant is not in use, such as in its transport configuration, and the present invention can take advantage of using such space to reduce the overall height of the mobile aggregate processing plant in its transport configuration compared to its overall height in its operating position.
  • the mobile chassis is typically formed of a frame having an undercarriage, typically a plurality of wheels on each side, optionally with a caterpillar-type track or tracking around the wheels in a manner known in the art.
  • the crusher in the mobile aggregate processing plant is a jaw crusher, generally comprising a pair of opposing crusher jaws arranged to have an area between the jaws to crush material.
  • the jaw crusher has an upper opening or throat for loading material into the crusher at or near the upper ends of the crusher jaws, and a lower discharge opening at or near the lower end of the jaws.
  • One or both of the jaws are moveable relative to the other jaw and/or jaw supporting elements, typically in a reciprocal or 'to and fro' motion, and optionally with an eccentric drive arrangement and/or mechanism, to carry out cycles of crushing and relieving action between the jaws to reduce the size of the loaded material to a smaller aggregate size for discharge through the lower discharge opening.
  • one jaw of a pair of crusher jaws in a jaw crusher is fixed, and one jaw is moveable, and material to be processed through the jaw crusher is provided from a feed hopper or the like having a hopper discharge end at or near or above the upper loading opening of the jaw crusher.

  • the mobile aggregate processing plant comprises a feed hopper for providing feed material to the crusher.
  • one or more parts of the feed hopper are moveable between a transport configuration and an operating configuration, optionally to help reduce the overall height of the processing plant in its transport configuration.
  • the mounting of the mobile aggregate processing plant comprises at least two height extenders.
  • the mounting comprises four height extenders, optionally arranged in a square or rectangular configuration on the chassis.
  • the height extenders may comprise any suitable design, size or shape, able to alter the overall height of the mobile aggregate processing plant between the transport configuration and the operating configuration, relative to the chassis.
  • the height extenders comprising tie rods, or adjuster rods, or upstanding bolts.
  • the rods or bolts are optionally threaded, and made with complimentary female parts on one or more of the crusher and the chassis.
  • the height extenders may include one or more plates and/or nuts, adapted to work in conjunction with the upstanding rods or bolts, in order to alter the overall height of the mobile aggregate processing plant

  • Transport containers such as shipping or haulage or road containers, are also well known in the art, and typically have a number of known and regular dimensions, to provide compatibility with the means of transport, such as trucks and/or transport vessels including ships.
  • One well known form of transport container is the "ISO 40 foot" container whose general internal dimensions are approximately 12m in length, between 2.3 and 2.4m in width, and 2.4m in height.
  • ISO 40 foot container As the ISO 40 foot container is so well known and used, the cost of shipping an ISO 40 foot is now a relatively world wide standard cost compared to the cost of shipping a bespoke piece of machinery.
  • ISO 40 'high cube' containers typically having the same length and width as the standard ISO 40 foot container, but having a higher height of 2.7m with a door aperture height of up to 2.6m, typically close to 2.6m.
  • the mobile aggregate processing plant of the present invention can be located within an ISO high cube container in its transport configuration.

  • the layout and operation of the processing plant 2 as shown in figure 1 is in general similar to conventional mobile aggregate processing plants, based on having a chassis 4 on an undercarriage 12, generally being in the form of two caterpillar-type tracks located at or on each side of the chassis 4, to provide some local mobility of the processing plant 2 at a location or at a particular site.
  • Caterpillar-type undercarriages 12 are well known in the art and are not further described herein.
  • the chassis 4 includes a conveyor mounting unit 14 able to house and support the conveyor 8.
  • the conveyor 8 is typically based on a conveyor belt (not shown in figure 1 ) moveable about two end drums 16, with a lower end of the conveyor 8 being below a discharge outlet of the crusher 6 to initially transport material away from the crusher 6 in the direction of arrow 106, along to arrow 108, and an upper end, typically higher above the ground surface 3, having a discharge able to pass processed material in the direction of arrow 110.
  • feed material to be processed by the processing plant 2 is fed as per arrow 102 into a suitable area, typically formed in the nature of a hopper having raised sides 32.
  • the feed material may be deliberately urged by one or more elements, belts or similar, to pass as per arrow 104 into an inlet opening of the crusher 6.
  • a conveyor 8 can be either fully removed from a conventional mobile aggregate processing plant, or either partly removed, especially towards an upper end, and/or folded, typically around a centre or near centre junction.
  • the conveyor 8 is hinged at a central mid or near midpoint 30 along the length of the conveyor 30, to create upper and lower conveyor sections, such that an upper section can be detached or folded to provide a more compact overall mobile aggregate processing plant 2.
  • the raised sides 32 of the feed area are also removable or foldable or hingeable or otherwise separable, or a combination of the same, so as to help reduce the overall height of the processing plant 2 at the feed area of the processing plant 2.
  • the crusher 6 of the example of a mobile aggregate processing plant 2 of the present invention shown in figure 1 is a jaw crusher, comprising two jaws, one being a fixed jaw 20 at an oblique angle relative to the ground surface 3, and a moveable jaw 22 generally being in a perpendicular direction to the ground surface 3, and moveable via an engine 24 engaging the moveable jaw 22.
  • a fly wheel 26 on each side of the top end of the moveable jaw 22 provides inertia for the moveable jaw 22, to help operate the moveable jaw 22 in the manner of the known operation of a jaw crusher, wherein cycles of crushing and relieving action on material provided into the crusher 6 reduce the material to a size that allows its discharge or exit through the lower discharge opening between the jaws 20, 22 and onto the lower end of the conveyor 8 for discharge from the processing plant 2 in the direction of arrows 106, 108 and 110.
  • the processing plant 2 shown in Figure 1 has a height above the ground surface 3 to the top of the fly wheels of h1.
  • crushers in particular jaw crushers, to seek to maximise the loading opening, so as to be useable for as many different locations or sites or operations.
  • increasing the size of the jaws and the loading opening requires greater power, and in particular a relative increase in the size of the associated fly wheels for the moveable jaw.
  • fly wheels there is increasing extent of the fly wheels above the highest level of the chassis above a ground surface.
  • crushers in particular jaw crushers, to have an appropriate space or height below its discharge outlet, to allow processed material to sufficiently fall away, and so to prevent blockages at the discharge outlet.
  • the bigger the appropriate space or height below its discharge outlet the better
  • a crusher is secured to the chassis during manufacture, so that the conventional crusher has a fixed set of dimensions for the processing plant, which, if not available to match transport height restrictions, typically road height conditions, and/or any suitable transporting facilities such as a standard ISO 40 foot container, requires bespoke transport consideration.
  • Bespoke transport typically requires exceptional transport costs, in particular shipping costs. Such shipping costs can currently exceed $15,000 or more, as the jaw crusher requires exceptional or non-standard space to be transported.
  • the present invention can take advantage of the space or height required in use below the discharge outlet of the crusher, to alter the overall height of the mobile aggregate processing plant between a transport configuration and an operating configuration. Lowering the overall height of the mobile aggregate processing plant allows certain mobile aggregate processing plants to meet certain transport height regulations or restrictions. In the way, the present invention can allow larger sized mobile aggregate processing plants than hitherto possible to be conveniently transported from place to place.
