· Long - distance Conveying: In large - scale open - pit mines, polyester mesh belts are often used for long - distance ore conveying. Their high strength and wear - resistance enable them to bear the weight of large amounts of ore and the wear caused by continuous conveying. For example, in iron ore mining, the polyester mesh belt can stably transport iron ore on the long - distance conveyor from the mining face to the concentrator, ensuring the continuity of production. Moreover, the flexibility of the polyester mesh belt allows it to adapt to the undulations of the terrain and operate normally on curved conveyor routes.
· Fine Material Conveying: For some fine ore materials after crushing and grinding, the polyester mesh belt can effectively avoid material residue due to its smooth surface and non - stick property, ensuring accurate conveying. For instance, in gold ore beneficiation, the ground gold - bearing ore powder is conveyed to the subsequent extraction process through the polyester mesh belt without loss caused by material adhesion, improving the gold recovery rate.
· Cooperating with Screening Equipment: During the ore screening process, the polyester mesh belt can be used as the conveying part of the screening equipment. It evenly transports the ore to be screened onto the sieve, ensuring that the ore can be fully screened on the sieve. For example, installing a polyester mesh belt in front of a vibrating screen can ensure that the ore smoothly enters the sieve surface, improving the screening efficiency and quality.
· Conveying after Classification: After the ore is classified by the screening equipment, the polyester mesh belt is responsible for transporting the ores of different particle sizes to the corresponding storage or processing areas. Its precise conveying and positioning function enables ores of different grades to be accurately transported to the designated locations, facilitating further processing.
· Tailings Conveying: In the tailings treatment process, the polyester mesh belt is used to transport tailings from the concentrator to the tailings pond. Since tailings may contain some corrosive substances, the polyester mesh belt has good chemical corrosion resistance and can operate stably for a long time in the harsh tailings conveying environment, reducing equipment maintenance and replacement costs.
· Tailings Dewatering: The polyester mesh belt can also be applied to the tailings dewatering process. In the dewatering equipment, the polyester mesh belt serves as the medium for carrying tailings. Its good air - permeability helps the rapid discharge of water, accelerating the tailings dewatering speed and reducing the water content of tailings, which is convenient for subsequent tailings storage and treatment.
· Coarse Screening Operations: At the mining site, the coarse sieve made of stainless - steel wire mesh is used for the preliminary screening of freshly mined ore, removing large - sized rocks and impurities. Its high - strength structure can withstand the impact of large ore blocks, ensuring the smooth progress of screening. For example, in coal mining, the coarse sieve can initially separate coal blocks from impurities such as gangue, improving the quality of coal.
· Fine Screening and Filtration: In the further processing in the concentrator, stainless - steel wire meshes of different mesh numbers are used for fine screening and filtration of the ore. The fine sieve can accurately separate ore particles of different sizes to meet the requirements of different processing techniques for ore particle size. In some wet beneficiation processes, the stainless - steel wire mesh filter is used to filter solid particles in the ore pulp, obtaining pure ore pulp and providing high - quality raw materials for subsequent extraction and refining processes.
· Magnetic Separation Process: In the magnetic separation process, the stainless - steel wire mesh can be used to make some components of the magnetic separation equipment, such as the protective mesh on the surface of the drum. It can protect the drum from the wear of ore without affecting the magnetic field, ensuring that magnetic ores can be effectively separated.
· Gravity Separation Process: In the gravity separation operation, components such as chute linings or vibrating plates made of stainless - steel wire mesh help improve the efficiency of gravity separation. Its smooth surface and appropriate structural design enable ore particles of different densities to be better separated under the action of water flow, increasing the enrichment degree of minerals.
· Equipment Protection: In mining and mineral processing equipment, many components are prone to wear by ore. The stainless - steel wire mesh can be made into protective sleeves, linings, etc., and installed at the easily worn parts of the equipment, such as the feed inlet of the crusher and the idler of the conveyor belt. The high wear - resistance of the stainless - steel wire mesh can significantly extend the service life of the equipment and reduce equipment maintenance and replacement costs.
· Pipeline Protection: For pipelines transporting ores, ore pulp, and other materials, the stainless - steel wire mesh can be used as a lining material to enhance the wear - resistance of the pipeline. Especially in some high - speed flowing ore pulp pipelines containing solid particles, the stainless - steel wire mesh lining can effectively resist the erosion of particles, reduce pipeline wear, and improve the safety and service life of the pipeline.
