Description

Improved palate applicable in mills aggregates or minerals.

Object of the invention

The invention relates, as expressed by the statement of the present specification, to a palate perfected applicable in aggregate or mineral mills, providing to the function to which a number of advantages are intended and features, which will be described in detail below, and that They represent an innovative improvement over existing ones currently.

More specifically, the improvement that is introduces into the palate that advocates the invention modifies the configuration of the same, so that the camera is enlarged mill crushing, leading to an accumulation of material in said area, which allows a notable increase in production Total at a lower cost.

Scope

The field of application of the present invention it is specifically that of aggregate or mineral mills, especially of the type that incorporates a rotor provided with bars blenders that rotate within a stator in which they participate palates

Background of the invention

As is known, the mills of the type here concerns, incorporates a rotor, conveniently motorized, of which a plurality of bars intended to act on the products to be crushed.

A series of jaws or impact plates belonging to palates arranged around of said rotor, act as sufrideras, so that they impact on aggregates or minerals likely to be crushed at go through the space between them and the blender bars that rotate with the rotor.

Being said relatively narrow space, and given the high abrasive power of aggregates and other products, it produces rapid wear of both the blender bars and the jaws, the material being crushed by strangulation or by friction with said parts of the mill and by impact.

All this translates into the need for a constant regulation and replacement of worn parts, with the consequent increase in costs and lower performance in the production.

Explanation of the invention.

Thus, the perfected palate applicable in aggregate or mineral mills advocated by the present invention, It constitutes an obvious novelty within its scope, since, as its innovative configuration has been mentioned enlarges the crushing chamber, favoring the accumulation of material in its lower part, with which it is possible to alleviate notably the problem described.

Specifically, the perfected palate modify its configuration by incorporating a zone bounded by impact plates, optionally variable in position by translation or rotation, which preferably adopts a stepped shape creating a material accumulation space or deposit that moves with the palate, thus increasing the crushing chamber capacity.

Consequently, this step accumulates greater amount of material, since at that step the material from the vertical free fall of the chamber itself, plus the material that moves the beater bars of the rotor, causing an area of less elasticity to the rebound of the material, also adding the overflowing material from the tank created in the palate step, which, after the impacts of material on the upper area of the chamber, has accumulated, occupying the vertical of the new storage area, less rebound elastic of impact.

This greater accumulation of material in this zone of maximum narrowing makes it collide stone against stone, that breaks the aggregates or minerals by strangulation and friction between them with an impact component, which is translates into less wear on both impact plates and the blender bars of the rotor, and in a greater production of crushed material.

It should therefore be noted that the palate perfected allows to expand the camera capacity of crushing, which increases production, while producing a saving of the intervening wear parts, that is both on the impact plates and on the blender bars of the rotor and the breaking of more material against material, creating at the same time a floating camera that slides or moves With the palate.

The new perfected palate applicable in aggregate or mineral mills therefore represents a innovative structure of structural features and constitutives unknown so far for that purpose, reasons that together with its practical utility, provide it with sufficient foundation to obtain the privilege of exclusivity that is requested.

Description of the drawings

To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, is attached herein descriptive, as an integral part of it, of a game of planes, in which with an illustrative and non-limiting nature, represented the following:

Figure number 1.- Shows a view side elevation schematic of an aggregate mill in which appreciate the disposition of the main elements that configure, incorporating a possible example of palate perfected according to the invention.

Figures number 2 to 4.- Show respective alternative examples of realization of the perfected palate of the invention.

Preferred Embodiment of the Invention

In view of the aforementioned figures and of according to the numbering adopted, it can be seen in them as the perfected palate applicable in aggregate or mineral mills which advocates the present invention comprises the parts that are Indicate and describe below.

Thus, as seen in Figure 1, the Mill (1) has a crushing chamber (2) inside which has a rotor (3) that revolves around an axis (4), of the that a plurality of blender bars (5) intended to act on products to Crush.

A series of impact plates (6) belonging to two upper (7) and lower (8) palates arranged in an envelope around said rotor (2), they act so that they impact on aggregates or minerals as they pass between these and the mentioned mixer bars (5) that rotate with the rotor  (3).

Characteristically, the palate (8) incorporates an area delimited by the structure (9) of the palate (8) and the impact plates (6), which can optionally be variables in position by translation or rotation by incorporation of suitable means for such variation such as shafts, hinges, or similar.

Said area preferably takes a form staggered creating a storage space (10) for accumulation of material that moves with the palate (8), thus increasing the crushing chamber capacity (2).

In the area of maximum narrowing (11), enter the blender bars (5) and the impact plates (6), is where preferably produces crushing, as it accumulates more amount of material, from the vertical free fall of the own chamber (2), of the material that moves the mixer bars (5) of the rotor (3), and of the overflow material of the tank {10) of accumulation created on the palate (8).

This greater accumulation of material in this zone of maximum narrowing (11) causes it to collide with each other, that is, stone against stone, breaking by strangulation or friction between the material itself and impact, which translates in less wear of both the impact plates (6) and the blender bars (5) of the rotor (3), and in a greater production of crushed material.

It should be noted that the described deposit (10) of accumulation created on the palate (8), will have more or less capacity depending on the arrangement of both the impact plates (6) of the palate (8) as the configuration of its structure (9), being able to this will vary according to the needs of each case, as see in figures 2 to 4.

Finally, it is noteworthy, that even when in the example represented the mill only has two palates, the The invention provides for the possibility that the mill may have three or more

Describe sufficiently the nature of the The present invention, as well as how to implement it, is it states that, within its essentiality, it may be taken to the practice in other embodiments that differ in detail from the one indicated by way of example, and which will reach also the protection that is collected as long as it is not altered, change or modify its fundamental principle.
