For example, the grinding members 21,22,23,24,25,31,32,33,34,35 are distributed and joined along two parallel and juxtaposed rotating shafts 2,3, each passing through the N grinding chambers CB1, CB2, CB3, CB4, CB5, the two rotational shafts 2, 3 being driven in counter-rotating directions of rotation and so as to grind the products in each of the chambers by the joint action of the grinding members 21 , 22,23,24,25, 31,32,33,34,35, counter-rotating, carried by the two rotation shafts. In general, and for i between 1 and N, the grinding members marked 2i and 3i respectively carried by the rotation shafts 2 and 3 ensure the grinding of the materials in the CBi chamber. Thus, and in the example of the figures, the grinding members marked 21, 31 respectively carried by the rotation shafts 2 and 3 ensure the grinding in the first grinding chamber CBI. The grinding members marked 22,32 respectively carried by the rotation shafts 2 and 3 ensure the grinding in the first grinding chamber CB2. Grinding bodies marked 23,33 carried respectively by the rotation shafts 2 and 3 ensure the grinding in the first grinding chamber CB3, etc.

In each grinding chamber CBi, the grinding members 2i and 3i can be arranged in staggered rows on the two rotation shafts 2 and 3, and in such a way as to ensure the entanglement of the grinding members 2i and 3i, as illustrated in FIG. As a non-limiting example in Figure 5. The grinding members may take the form of each ring gear, namely a ring having teeth on its periphery.

The choice of the specificities of the grinding members depends on the material of the flow of products to be milled in the grinding chamber CBi.

For example, and for the grinding of metallic material (metal can or aluminum can), glass, or for the grinding of plastic material, it is preferable to use metal grinding members, and where appropriate with dimensions and dimensions. conformations (ie toothing) of the crushed material. For easier to reduce materials such as paper or even cardboard, one can make the choice of hard plastic grinding member, at least in part, for the purpose of cost reduction.

According to one embodiment, the storage chambers CS1, CS2, CS3, CS4, CS5 are independently removable elements of said housing of said device. These tray elements can be removed independently of each other from the device.

For example, and as illustrated in the figures according to a nonlimiting example, each removable storage chamber CS1, CS2, CS3, CS4, CS5 takes the form of a drawer T1, T2, T3, T4, T5 which can be inserted or removed from the housing 10, simply by sliding in the housing.

Advantageously, each storage chamber CS1, CS2, CS3, CS4, CS5 may have a window F, transparent or translucent, to know the internal filling level of the storage chamber. These windows F, present on a visible face of the device allow to know the filling level of the different storage chambers CS1, CS2, CS3, CS4, CS5, from the outside, and without having to remove the removable element.

All or part of the storage chambers CS1, CS2, CS3, CS4, CS5 may have, as illustrated for information in Figure 6, a double bottom for trapping liquids. A cavity is thus formed between the sealed bottom of the tank, and a perforated upper wall kept away from the sealed bottom and whose openings are intended to be traversed by the liquids. These openings, however, are small enough to hold the broyais. An opening of the sealed bottom, closed by a removable cap can allow to empty trapped liquids.

For reasons of safety, the device 1 may have removable flaps VI, V2, V3, V4, V5 capable of closing the inputs of the different reception chambers CRI, CR2, CR3, CR4, CR5, each flap, with a function of shutter, able to pass from a first open position, allowing the loading of the corresponding receiving chamber, to a closed position of the input. Each flap may be a sliding element or pivoting on the housing structure to move from the first open position to the closed position or vice versa.

Moreover, the device may comprise a security system having: - N position switches CTI, CT2, CT3, CT4, CT5, independent, associated with N moving flaps VI, V2, V3, V4, V), each position switch being actuated by the corresponding movable flap, in said closing position of said movable flap, - a control unit UC comprising means for authorizing the start of said motorization means only when the N position switches CTI, CT2, CT3, CT4 , CT5, independents signal the good closing of the N movable shutters.

Alternatively or addition, the security system may include an electronic lock that allows the activation of the motorization means only after the entry of a secret code on a keypad, the device, especially on the front of the device.

Each position switch CTi, usually also called limit switch is an element that opens or closes an electrical circuit when the associated flap is in its fully closed position. The UC control unit uses these electrical switches to enable the start of the grinding means, if and only if the switches indicate that all the shutters are closed.

The device may also comprise pusher systems PI, P2, P3, P4, P5, respectively for the different reception chambers CRI, CR2, CR3, CR4, CR5. Each pusher system comprises a handle outside the casing 10, integral with a movable pusher, internal to the receiving chamber, via a rod passing through the wall of the housing 10, the rod of the pusher possibly being guided by a support sleeve secured to the housing 10.

This pusher system allows, by a manual action, external, to push the internal products to the CRi receiving chamber towards the mechanical grinding means, and thus without risk to the user. This ensures that the products introduced into the receiving chamber are reduced in the grinding chamber, despite the phenomena of jamming of materials that may appear in the chamber. The pusher stroke is limited by one or more physical stop (s) prohibiting the meeting of the pusher with the organs of the mechanical grinding means.

The device can be in the form of furniture and can have dimensions less than or equal to 85 cm x 75 cm χ 60 cm (height, width, depth) to integrate directly with individuals. The size of the device can be greater, especially for non-domestic applications or for professionals (commerce, restaurant ...).
