Definitions
- the invention is in the field of machine tools of the type of industrial mills and particularly, without restriction, shredders scrap.
- the invention is in fact an improvement of existing mills which allows an increase in the hourly production of crushed material, a decrease in the intensity load of the electric motor driving the mill, a significant decrease in the wear of the inner walls of the mill. as well as hammers of the grinding rotor and the anvil.
- the current grinders (see FIG. 1), in particular the scrap crushers, consist of an internal main casing inside which rotates a rotor driven by an electric motor. Said rotor is provided on its periphery with hammers adapted to cooperate with the edge of an anvil integral with the housing.
- the housing has an inner wall covered with heavy-duty armor plates.
- the material to be ground is injected into the casing through an opening generally located near the rotor.
- the material to be ground is conveyed to the mill by a conveyor belt which feeds the mill continuously.
- the material to be ground is driven by the rotation of the rotor, crushed by crushing between the hammers of the rotor and an anvil.
- the fragments of crushed material are then dragged tangentially on the wall of the casing to the portion opposite the feed opening to be projected in the upper part of the casing which comprises a grid disposed above the rotor and whose dimension of meshes is defined to determine the granulometry of the output product: only the crushed material fragments having reached the desired particle size, defined by the mesh size of the grid, can be ejected.
- fragments of comminuted material having reached the desired particle size is meant in the present text fragments whose particle size is that defined by the dimensions of the grid located in the upper part of the housing or a smaller particle size.
- the fragments that can not be ejected fall back into the crankcase and are picked up again by the rotation of the rotor and crushed again.
- the side wall of the housing is provided, under the level of the grid, an airtight ejection door, closed during the grinding time and moved by jacks.
- This door has the function of allowing the immediate ejection of pieces imbroyant material so that they do not remain in the grinding circuit and do not lead to degradation of the rotor and / or hammers and / or the anvil and / or walls of the housing.
- This also has the effect of increasing the wear of the housing walls and the hammers of the rotor because of the friction generated by these fragments that could be avoided if said fragments had been ejected.
- the invention makes it possible to overcome the disadvantages of the existing systems and to considerably improve the performance of the mill while increasing the service life of the mill parts (crankcase walls, hammers, rotor, anvil) with the result that the load is reduced. of the electric motor driving the grinding rotor.
- the invention proposes an ejection door for a crusher casing, particularly a scrap crusher, characterized in that it comprises at least one light of defined dimensions and at least one deflector positioned facing and above said light, on the inner face of the ejection door forming a predefined acute angle of attack with said ejection door, said deflector being positioned parallel to the axis of rotation of the ejection door.
- said ejection door is a door for a crusher housing side wall.
- the applicant has been able to show that the piercing in the ejection door, particularly when the door is located in the side wall of the housing, lights defined dimensions and laying on the inner face of this door, to the inside the housing, a deflector oriented substantially towards the axis of the rotor, at said lights substantially on the upper edge of the light, covering said slots and forming an acute angle of given dimension with said ejection door, thus providing an additional permanent opening in the housing, allows the fragments having the desired particle size to be ejected at any time, even when they do not have the climbing speed to cross the grid.
- the baffle may be fixed by any appropriate means either directly to the ejection door or to a plate that will be attached to the ejection door.
- the deflector can be fixed on the ejection door between the axis of articulation of the door on the housing, when it is placed at the upper part of said door and the upper edge light.
- the purpose of the deflector is to create an obstacle in the circuit of fragments of crushed material that revolves around the rotor. Said fragments then hit the obstacle and are returned to the opening thus made in the ejection door of the mill.
- the fragments of higher particle size are stopped by the edges of the lights and then fall back into the circuit and feed the rotor.
- baffle coming to rest on each of the side walls, these walls also make it possible to solidify the assembly by creating a support for the deflector on the ejection door.
- the side walls have the dimensions defined by the length of the baffle, the height of the ejection door and the angle of attack formed by the baffle and the part on which the deflector is fixed.
- the side walls can be fixed by any appropriate means either directly on the ejection door, or on a plate on which can also be fixed the deflector and which will be attached to the ejection door.
- a preferred attachment means of the side walls is the weld.
- the invention proposes to provide at least one exhaust hood on the ejection door of a mill.
- the ejection door itself has dimensions identical to that of a conventional ejection door and may be in the same material as originally supplied by the mill manufacturer in which it is installed.
- the invention object of the present application can be applied to any ejection door of any grinder.

In this latter variant the manufactured door will replace that originally provided by the manufacturer of the mill in which it is installed. In this case the ejection door equipped with the present invention will have the dimensions of the original door and will be manufactured in any material compatible with the use for which it is provided. Mention may be made, for example, of steel, particularly without limitation, molded manganese steel or even chromium-vanadium steel.
- the ejection door comprises a plurality of lights, they are formed next to each other along the longitudinal axis of the ejection door.
- the lights can take any known shape. They can be circular, square, rectangular, triangular, or elliptical. Preferably the lights have a square shape.
- the dimensions of the lumens are defined by the particle size of the crushed material fragments that are to be obtained.
- the skilled person knows how to adapt said dimensions to the particle size that he wishes to obtain.
- the baffle is advantageously mounted removably on the door, which facilitates replacement after wear.
- the deflector can be attached directly to the ejection door and fixed thereto reversibly by any appropriate means, such as for example screwing, bolting, welding, interlocking or slide mounting. .
- the deflector may be attached to a plate of the same material or material different from that of the deflector, itself comprising at least one light having at least the dimensions of the light made in the door of ejection and said plate having outer dimensions greater than those of light, this plate being mounted on the door reversibly by any suitable means.
- the invention therefore also relates to an ejection door plate (9, 19, 29, 39, 49) for a material crusher casing (1) as previously described, itself comprising at least one light having at least one less the dimensions of the light made in the ejection door and said plate having external dimensions greater than those of the light, this plate being mounted on the door reversibly by any appropriate means.
