It further comprises means for storing the materials 9, 9 'which it needs for its operation and, in addition to the fuel, for example for new aggregates or coatings and possibly for bitumen / emulsion 9. In FIG. only the supply of bitumen / emulsion 9 and water 9 'has been represented, the latter serving in particular for cooling the rotor of the milling machine 2. Some of these storage means may be of the buffer type, that is to say that they are reloaded regularly during the work of the machine without it being necessary to stop the machine.
- a milling machine 2 producing mills 7 followed by a crusher 3 is found. followed by a kneader and then a worm spreader 4.
- the milling machine makes it possible to pull the materials of the roadway over a determined height and width of this roadway, this body being transverse, that is to say perpendicular to the main longitudinal (antero-posterior) extension of the machine.
- the milling machine 7 can be a milling machine or other type.
- the crusher 3 located downstream of the mill is used to loosen and crush the mills and produces crushed and possibly kneaded mills 8 if the mixing function has been provided in the crusher.
- the crusher and the kneader are one and the same organ.
- the crusher 3 disposed under the machine consists in this example of a casing 30 open downwards and thus the milled pavement.
- the crankcase is also open at both its forward / upstream and back / downstream ends to respectively receive the gross costs produced by the milling machine (inlet / upstream) and to deliver the crushed costs (back / downflow) once these crushed.
- the mills received, crushed and delivered by the milling machine rest on the ground and the machine moves on this ground so that there is a relative displacement between the ground loaders and the crusher fixed under the machine.
- the crusher does not have an isolated crushing chamber above the ground, the mills remaining essentially on the ground.
- the width (transverse measurement on the machine) of the crusher corresponding to the width of the inlet of the housing (front / upstream end) is substantially equal to the length (transverse measurement on the machine and corresponding to the milled pavement width ) of the milling machine so that all the produced costs are directly swallowed in the crusher.
- a passive chute or an active medium, eg. rotary brushes or other, disposed at ground level allows to recover all the costs on the milling width to guide them to the input before / upstream of the crusher.
- the crusher casing internally comprises two parallel rotors 32 elongate in the longitudinal direction of the machine.
- the two rotors 32 are substantially parallel to the longitudinal extent of the roadway and they radially comprise 31 metal blades.
- the rotors are rotated by a motor member 33, typically hydraulic.
- the drive of the rotors uses in this example a chain whose links engrain on toothed pulleys of the rotors and the drive member.
- the housing, the rotors and the drive member are carried by a frame (symbolized / partially represented by the amount 34 in Figures 1 to 3) to be fixed under the machine. Bearings, in particular bearings, are implemented between the moving and stationary parts of the crusher.
- Each rotor comprises fixed on its periphery blades which have in this example identical shapes and dimensions.
- the shape shown is a circular segment, that is to say a circular sector, the tip / top of which is towards the rotor.
- This segment / sector has a peak / peak angle of between 90 ° and 10 ° and is about 80 ° in the Figures. Lespales thus end in an arc at their free end opposite their point / vertex fixed to the rotor.
- the rotation of the rotor drives the blades which thus sweep a tubular sweep space when viewed along the axis of rotation of the rotors.
- the two rotors and the blades are arranged in the housing so that the two tubular scan spaces interpenetrate in an interpenetration zone where blades of the two rotors arranged in parallel planes between them may come two by two, in pairs 35, vis-à-vis a short distance from one another, a spacing / clear space determined gap then being present between the two blades 35 concerned. It will be understood that, due to the rotation of the blades, this spacing of determined spacing will be temporary and evolutive for the surfaces coming from the respective vis-à-vis of the blades and will be repeated at different times and different locations for pairs of different blades, the two blades of a pair concerned being two rotors.
- this difference is one of the main parameters allowing to modify the granulometry of the crushed costs. For example, with a determined difference between the two blades vis-à-vis the pair of about 15 mm can be obtained crushed mills having a homogeneous particle size, continuous, with a controlled dmax between 10 and 14 mm. These values are indicative and can be modified as needed.
- the free edge in a circular arc of each blade has a bevelled / tapered portion and possibly the upper / adjacent portion of / the side edges. Thanks to this, it is possible to lower the crusher as low as possible, until the blades are flush with the surface of the milled pavement, or even to slightly nibble it, without this creating too much resistance to the rotation of the crushers. rotors because it is a small surface (the end of the bevel) that hits the surface of the milled pavement. Thus, in the lowest possible position of the crusher, even without nibbling, if a hump present on the surface of the milled pavement is encountered, there will be less risk of blocking the rotation.
- an overload / lock detector can be implemented on the drive member or a friction clutch or break is installed on the transmission to the rotors.
- a metal detector can be provided in front of the machine or crusher.
- cutting elements for example on the rotors or overhanging them and which are intended to cut son, for example a detection loop on the road, which would become entangled on the rotors.
- the blades can be arranged on the rotors in various ways as long as the crushing occurs, in particular thanks to the shearing effect of the two blades of the pair of the two rotors which come opposite each other in the zone of interpenetration. .
- This is preferably achieved with blades which are flat metal plates and which are parallel to each other for those participating pairs coming in opposite short distance determined between them in the interpenetration zone.
- this result can be obtained with blades which are all in parallel planes and perpendicular to the rotors which, it is recalled, are parallel to each other.
- the rotors are horizontal and longitudinally elongated and the blades are in vertical transverse planes.
- Another solution corresponds to the case where the blades are divided from the point of view of their orientations into two groups. Within each group the blades are in planes parallel to each other. Each rotor has blades of the two groups and the pairs of blades coming in opposite and with the described gap belong to the same group, in a pair one of the blades being on one of the rotors and the other blade on the other rotor.
- the planes carrying the blades are no longer perpendicular to the axes of the rotors but inclined with respect to this axis. Preferably, the inclinations are symmetrical between the two groups.
- the blades are all in planes vertically considering the horizontal rotors. It is understood that other provisions of the flat plates forming the blades are possible to obtain the same result crushing costs with creation of a determined difference between pairs of blades coming vis-à-vis in the interpenetration zone.
- the casing of the crusher is open downwards and thus to the roadway as well as to the front / upstream and the back / the downstream for the passage of the costs at the entrance and exit of the crusher.
- the housing encloses the rotors and their blades laterally and on the top.
- the casing matches the shape of the two tubular scan spaces. This housing avoids the projections of the aggregates and costs and participates in the crushing of the costs and possibly to the mixing if this one is planned.
- a kneader is also implemented within the machine.
- This kneader makes it possible to knead the crushed loads with an asphalt binder and / or a certain proportion of aggregates or even "new" mixes in order to regenerate certain properties of the pavement.
- This kneader can be independent of the crusher but, alternatively, it can be integrated into the crusher.
- the rear / downstream part of the crusher comprises at least one orifice for introducing these additional products.
- the structuring of the blades is modified in this rear / downstream portion of the crusher, for example with a shape and / or a different orientation of the blades and / or a spacing / gap greater gap between the blades of the pairs coming in vis-à-vis the orientation and / or the gap in front / upstream or crushing must be predominant.
- pallets 38 are installed in the rear / downstream part of the crusher in order to allow efficient mixing of the crushed mills on which a binder has been spread by a set of nozzles 39.
- FIG. 7 An additional member can be seen in FIG. 7 at the front of the crusher 3 and outside its casing 30.
- This additional member is a means of active drive of the costs produced by the milling machine which is located even further in front of the crusher. 3, active drive towards the inside of the crusher casing 3.
- This active drive means consists of two worms mounted on two previous extensions of the rotors 32, at the front of the casing 30.
- This drive means active can be omitted or made removable so that it is installed only for treated pavements for which the costs might have difficulties to pass into the crusher sump despite the fact that the machine that processes the roadway is moving forward.
- this active drive means is particularly useful if a binder is already introduced upstream of the crushing, at the milling machine.
- the speed of rotation of the crusher blades must be relatively high, and in any case higher than that conventionally encountered in kneading means.
- the speed of rotation of the rotors may be between 120 and 220 rpm and is preferably about 160 rpm.
- a subassembly of distribution 4 blended costs 8 by the kneader additional products 9 can spread over the width of the milled pavement.
- This distribution subassembly is typically of the type of transverse worm.
- a set-up and precompacting table 5 may be included in the distribution subassembly.
- this distribution subassembly is connected to the machine on the job site, this distribution subassembly being disassembled for transport between sites.
- the distribution subset is an integral part of the machine.
- the width of the crusher (transverse measurement on the crankcase) can be about 1.16 m with a spacing of the two rotors of about 0.43 m and the length of the crusher (longitudinal measurement between its inlet upstream / front and its outlet downstream / rear) of about 1.5 m and the height of the crusher (maximum vertical measurement on the crankcase) can be about 0.5 m .
- the invention can be implemented with a machine which performs only a simple milling and is attached at the rear a towed equipment including the crusher and possibly the kneader and, preferably, the subset of distribution and possibly the table setting up and precompacting.
- the equipment towed by the simple milling machine is only the crusher and, on the other hand, the mixer and other downstream equipment is another stand-alone machine with a table for setting up and pre- compaction that flows autonomously from the single milling machine that is upstream.
- the equipment towed by the simple milling machine is only the crusher with its integrated mixer and, on the other hand, the other downstream equipment is another stand-alone machine with a set-up table and pre-compacting which flows autonomously from the single milling machine which is upstream. It is understood that many other equivalent arrangements are possible to implement the crusher of the invention and its eventual integrated mixer.
- the method of the invention follows from the description made so far with the implementation of a machine with which one practices a milling of the pavement then a crushing of the costs then a mixing of the crushed costs with additional products then one distributed materials obtained on the roadway, crushing and mixing taking place in the same body of the machine.
- additional products are typically an asphalt binder and / or aggregates or even asphalt.
