Description of a Preferred Embodiment

[0055] The invention, subject matter of the present patent application, is a shredder that comprises two independent elements working together: a movable assembly (1) and a drive unit (2), the drive unit (2) being in charge of supplying energy to the movable assembly (1).

[0056] The movable assembly (1) (whose sectional view can be observed in FIG. 1) comprises a frame (3) and a system of caterpillar tracks (4) which provides the movable assembly (1) with the feature of the mobility.

[0057] The remaining components of said movable assembly (1) are placed on the frame (3) of the movable assembly (1). Among the remaining components are the following: [0058] a feeding system (5), [0059] a dosing roller (6), [0060] a shredding element (7), [0061] a metal extraction conveyor belt (8), and [0062] an outgoing conveyor belt (9) of shredded material.

[0063] The movable assembly (1) of the movable shredder, subject matter of the invention, in regard to this specification, is divided into three areas: [0064] waste feeding area (A), [0065] waste treatment area (B), [0066] waste extraction area (C).

[0067] The feeding system (5) that comprises several metal plates (10) attached to a metal feeding conveyor belt (11) supported on a lattice (12) is located in the waste feeding area (A) and, following the path along which the material to be treated travels, next there is a material entrance ramp (21).

[0068] The feeding conveyor belt (11) has such a shape that the extremity of the feeding conveyor belt (11) located in the farthest portion of the treatment area (B) is positioned at a height such that the material load is carried out easily. The feeding conveyor belt (11) is provided with a first upward section ending in a horizontal section.

[0069] In a preferred embodiment of the invention, the shredding element (7) is a hammer mill.

[0070] The waste feeding system (5) is covered with metal sheets (13), which make up a metal cover for said feeding system (5) and a reception hopper (14) for material located in the farthest portion of the treatment area (B), said metal sheets (13) together with the feeding conveyor belt (11) guide the incoming waste materials introduced by said reception hopper (14).

[0071] Following the path along which the waste materials travel within the movable assembly (1), at the treatment area (B) entrance a dosing roller (6) is located. Before said waste materials come into the shredding element (7), by means of the dosing roller (6) the size and quantity of material entering the shredding element (7) are monitored, thus avoiding the entry of large elements that could block the shredding element (7).

[0072] The dosing roller (6) is attached to the frame (3) by means of a fastening and guiding system, which comprises at least, four guides (17) and two hydraulic cylinders (18) that control the vertical motion of the dosing roller (6).

[0073] The shredding element (7) comprises: [0074] a shredding chamber (19) smaller in size than the shredding chambers of conventional hammer mills, [0075] a shredding mill (23), [0076] a lower closed base (20) unlike the conventional hammer mills that incorporate an lower exit grid for material, [0077] an vertical exit grid for shredded material (16a), [0078] an horizontal exit grid for shredded material (16b), [0079] an exit gate for non-shreddable material (15),

[0080] The material, which cannot be shredded into fragments or that is not coming out through the exit grids for shredded material (16a, 16b) comes out through the exit gate for non-shreddable material (15).

[0081] By means of the shredding element (7), high-density fragments of material are obtained.

[0082] Finally, in the waste extraction area (C), a metal extraction conveyor belt (8) collecting the fragments of material is located. Said metal extraction conveyor belt (8), besides absorbing the impacts of the shredded material, raises said shredded material up to the outgoing conveyor belt (9), which is made of conventional rubber.

[0083] The outgoing conveyor belt (9) raises the fragments of material in order to accumulate them into a stockpile of material already treated.

[0084] Finally, in the waste extraction area (C), the movable assembly (1) comprises a ferrous separation system and a dust removal system, which are already known in the state of the art.

[0085] The ferrous separation system comprises a band conveyor belt (22) located on the outgoing material conveyor belt (9), said band conveyor belt (22) comprises a continuous magnet to which the ferrous material sticks, in such a way that the ferrous fragments are conveyed with the movement of the band conveyor belt (22).

[0086] The invention should not be limited to the particular embodiment that has been described in this document. Any person skilled in the art may develop other embodiments in view of the description hereby disclosed. Consequently, the scope of the invention is defined by the following claims.
