[0003] However, in actual application, the above-mentioned ore screening machine still has the following shortcomings: the screens in the above-mentioned devices are mostly made of one-piece steel. During the long screening process, the screens are easily worn and thinned due to impact, wear, or a combination of impact and wear. After being worn and thinned, the screen holes are likely to become larger, which seriously affects the screening effect of the screen and also affects the service life of the screening device. Utility Model Content

[0004] The purpose of the present utility model is to address the above-mentioned deficiencies and provide a screen plate for ore screening equipment, which can effectively prevent the screen from being worn and thinned due to impact, wear, or a combination of impact and wear, thereby avoiding the situation where the screen holes become larger due to wear and thinning, ensuring the screening effect of the screen and extending the service life of the screening device.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A screen plate for ore screening equipment includes a screen plate body with multiple sieve holes. The screen plate body includes a steel plate layer, a rubber layer arranged on the steel plate layer, and a cast screen plate layer arranged above the rubber layer. The upper surface of the rubber layer is bonded to the cast screen plate layer, and the lower surface of the rubber layer is bonded to the steel plate layer.

[0007] Furthermore, the cast screen plate layer is cast from a wear-resistant alloy or metal ceramics.

[0011] The beneficial effects of the utility model are:

[0012] In actual applications, when the cast screen plate layer is subjected to impact, wear, or a combination of impact and wear, the cast screen plate layer is used to improve the overall wear resistance of the screen plate body, and the rubber layer produces a certain elastic deformation to weaken the impact force on the screen plate body, thereby ensuring the screening effect of the screen and extending the service life of the screening device. The utility model can effectively prevent the screen from being worn and thinned due to impact, wear, or a combination of impact and wear, avoids the situation where the screen holes become larger due to wear and thinning, thereby ensuring the screening effect of the screen and extending the service life of the screening device.

[0017] like Figure 1 、 Figure 2 and Figure 3As shown, a screen plate for ore screening equipment includes a screen plate body 1, on which a plurality of screen holes 11 are arranged. The screen plate body 1 includes a steel plate layer 12, a rubber layer 13 arranged on the steel plate layer 12, and a cast screen plate layer 14 arranged on the rubber layer 13. The upper surface of the rubber layer 13 is bonded to the cast screen plate layer 14, and the lower surface of the rubber layer 13 is bonded to the steel plate layer 12.

[0018] When the cast screen plate layer 14 is subjected to impact, wear, or a combination of impact and wear, the cast screen plate layer 14 improves the overall wear resistance of the mesh plate body 1, and the rubber layer 13 produces a certain elastic deformation to reduce the impact force on the mesh plate body 1, thereby ensuring the screening effect of the screen and extending the service life of the screening device. The utility model can effectively prevent the screen from being worn and thinned due to impact, wear, or a combination of impact and wear, avoids the situation where the screen hole 11 becomes larger due to wear and thinning, thereby ensuring the screening effect of the screen and extending the service life of the screening device.

[0019] like Figure 1 、 Figure 2 and Figure 3 As shown, the cast screen plate layer 14 is cast from a wear-resistant alloy or metal ceramics; in this embodiment, the cast screen plate layer 14 made of a wear-resistant alloy can increase the thickness of the steel plate layer 12, and can also enhance the wear resistance of the steel plate layer 12, avoiding the occurrence of wear and thinning or even enlargement of the sieve hole 11; the cast screen plate layer 14 cast from metal ceramics is first placed in a metal casting mold, and then high-temperature liquid metal is injected on the ceramic sheet, and cooled to form a metal-ceramic composite, which has good wear resistance and can avoid wear and thinning or even enlargement of the sieve hole 11.

[0020] like Figure 1 、 Figure 2 and Figure 3 As shown, the mesh plate body 1 is arc-shaped, and the cast screen plate layer 14 is an inner arc surface. In this embodiment, the inner arc surface made by the cast screen plate layer 14 prevents the ore from directly impacting and wearing the steel plate layer 12, thereby improving the wear resistance of the mesh plate body 1.

[0021] like Figure 1 、 Figure 2 and Figure 3 As shown, the thickness of the cast screen plate layer 14 is greater than the thickness of the steel plate layer 12 and the thickness of the rubber layer 13; in this embodiment, when the thickness of the cast screen plate layer 14 is greater than the thickness of the steel plate layer 12 and the thickness of the rubber layer 13, the wear resistance and service life of the mesh plate body 1 can be further improved.

[0022] like Figure 1 、 Figure 2 and Figure 3As shown, the screen body 1 is provided with a plurality of mounting holes 15 ; in this embodiment, the screen body 1 can be installed through the plurality of mounting holes.

[0023] The specific embodiments described herein are merely examples of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described, or replace them with similar methods without departing from the scope of the present invention.
