CPC B07B 1/469 (2013.01) [B07B 1/36 (2013.01); B07B 1/42 (2013.01)] | 14 Claims |
1. A mining screen comprising at least one propulsion element, the at least one propulsion element receiving at least one screening structure, wherein the mining screen is able to perform at least one vibration regime due a means of excitation, wherein the vibration regime promotes the screening of a material moving through the mining screen, wherein:
the screening structure comprises at least one panel screen provided with a plurality of apertures capable of screening the material moving through the mining screen;
the means of excitation are arranged in the at least one propulsion element;
the at least one propulsion element and the panel screen are manufactured from a first material, the first material comprising a composite material;
wherein the apertures of the panel screen are of varying dimension, wherein each aperture defines an area for the passage of the material, so that the areas of the apertures of the panel screen are altered due an excitation signal, the excitation signal configured as at least one of an electrical signal, a piezoelectric signal and a temperature signal;
wherein the panel screen is formed by at least the first material and a polymeric material, so that the first material acts as an insert to a coating of the polymeric material, wherein at least 80% of the panel screen is manufactured from the polymeric material;
the panel screen further comprising a shape memory alloy associated with the first material that alters the area of the apertures of the panel screen in response to a change in shape of the shape memory alloy when the excitation signal is connected to the shape memory alloy.
