- the teeth of each knife extend, in a tangential direction (to a circle connecting the knives), between two edges
- the edge 45 is said leading edge: it corresponds to the first of the two edges (delimiting the teeth of the knife) which passes on any reference radius, for example opposite a counterblade , during a rotation of the rotor in the primary direction of operation.
- the edge 46 is said trailing edge: it corresponds to the last of said edges which passes over the reference radius (or opposite the counterblade) during a rotation of the rotor in the primary direction of operation.

- the shims 15 are introduced by the mounting light 59; they are fixed to the beam 22 and positioned in the transverse direction in the same way as the counterblades 7 to 10, that is to say by means of fastening screws 18 and concentric screw adjusting systems 19.
- shims 15 have a flat face 16 which, when the shims are in the operating position, extends in the extension of the sidewall 34, constantly spaced from the knives so as not to cooperate with the latter.
- the waste is therefore ground only at the level of the counter-blades 11 to 14.
- the grinding device When the rotor rotates in the primary direction of operation, the grinding device therefore operates in a so-called granulation mode, in which the waste does not undergo only one type of grinding, by clean cut.
- FIG. 3 illustrates the device of FIG. 1, in which the counter-blade train 11 to 14 has been removed and replaced by a set of shims 15, as previously explained.
- the wedges 15 are introduced by the mounting slot 60, fixed to the beam 23 and positioned in the transverse direction in the same way as the counter-blades 11 to 14.
- Their flat face 16 extending constantly away from the knives, the waste is ground only at the counter-blades 7 to 10.
- the grinding device therefore operates in a mode called grating mode, in which the waste undergoes only one only type of grinding, by rolling and / or slicing and cutting.
- the invention thus provides a multifunction device, which adapts to all types of waste.
- the device can operate in the mode of grating in the configuration illustrated in FIG. 2: it suffices for this to be done turn the rotor in the opposite direction to the primary direction of operation, said secondary direction of operation.

- the same configuration therefore makes it possible to use the grinding device in the granulation mode or in the rasping mode.
- the counterblades 7 to 10 and 11 to 14 are present (configuration illustrated in FIG. 1), the grinding device can operate indifferently in both directions, for the same result. This makes it possible to halve the downtime of the device for maintenance reasons.
- counter-blades 7 to 10 and 11 and 14 are all identical.
- the invention thus makes it possible to obtain several types of grinding from the same parts.
- the same set of shims can be used to replace the counter-blade train 7 to 10 or the counter-blade train 11 to 14.
- each counterblade 7 to 10 and 11 to 14 are also reversible: each counterblade can be mounted, at the same location, in one direction or the other so as to reverse its leading edges and leak.
- each counterblade can be mounted, at the same location, in one direction or the other so as to reverse its leading edges and leak.
- the cradle 29 forming the discharge hopper 27 and supporting the screen 26 is equipped with at least three (four in the example shown) lower wheels 33. If they are fixedly mounted, these wheels 33 are oriented in the transverse direction (alternatively, they are mounted free to rotate about a vertical axis).
- the cradle 29 is slidably mounted in the vertical direction between a position said operating position and a position called release position. To this end, it is coupled to guide rails 62. In the operating position, the cradle can be rigidly fixed to the grinding chamber; in this case, it is fixed on each side of the grinding box, to a lower beam 30 of the base 53, 54 by screws 31; moreover, the screen extends at a short distance from the knives in rotation.
- the wheels of the cradle rest on the ground and the cradle, as well as the sieve and the discharge hopper, extend entirely below the crushing box so that they can be removed from the device; in this release position, the cradle carrying the sieve can roll on the ground in the transverse direction and be separated from the crushing chamber, to allow access to the rotor from below, to replace the sieve (for example by a sieve with different mesh sizes) or to clean it.
- the movement of the cradle between these two positions is effected by means of a jack 32. This arrangement makes it possible to have a low-height grinding device, compared to prior known devices.
- This arrangement also facilitates the handling operations of the cradle and the sieve, and in particular the operations of mounting and removal of said sieve and cradle relative to the grinding device.
- the grinding device according to the invention furthermore comprises a stationary feed hopper 24, whereas known prior devices have pivoting hoppers in order to allow access from above to the inside of the grinding box and to the rotor.
- a pivoting hopper such as the anterior hoppers has the disadvantage of requiring to move the conveyor belt waste leading to the hopper to allow the pivoting of the latter. These operations are complex and time consuming.
- the feed hopper 24 and the conveyor belt (not shown) associated are fixed mounted; the access to the rotor from above is effected by one of the hatches 36, 37, which considerably facilitates maintenance operations.
- Each hatch 36, 37 comprises a vertical portion forming part of one side walls of the grinding chamber, and an upper horizontal portion forming part of an upper wall of the grinding chamber.
- the vertical portion of the hatch 36 is pivotally mounted relative to the grinding box about two longitudinal axes 38, 39 facing in the transverse direction, the axis 39 being fixed relative to the grinding box, the axis 38 being pivotally mounted about the axis 39.
- the upper horizontal portion of the hatch 36 is fixed to the feed hopper 24 by screws 61 accessible laterally from the outside of the box.
- the hatch 37 is similarly arranged on the other side of the grinding box. To access the rotor from above, simply remove the screws 61 and tilt the hatch 36 (or 37) around the pivot axis 38 and the pivot axis 39.
- granulation and grating counterblades may not be identical. These counter-blades may not be arranged parallel to the horizontal median plane of the rotor. Note also that each counter-blade train (grating or granulation) can be replaced by a single counter-blade of great length.
- Each knife can be associated with two counter-blades arranged facing one another on the same diameter of the rotor. It should be noted in this case that the shearing face of said counterblades can not extend tangentially to the cutting circle (except possibly if these two counterblades have different thicknesses, thus offering distinct driving distances of one against -lame to another, a rolling effect and / or delay is then obtained at each counter-blade, but in a different degree from one against the blade to the other, resulting in distinct results in terms of grinding ).
- Each knife can be associated with three counter-blades or more.
- the trace, in a straight section, of the shearing face of the knives and / or against the blades can be curved.
- the shearing face of the knives and / or counterblades can form, with an adjacent face (at the leading edge or the trailing edge of the knife or against the blade), a higher angle or less than 90 °.
