The following is a more detailed introduction to the applications of wear-resistant plates in the mining industry, covering multiple aspects:

 I. Applications related to excavation equipment

1. Large mining excavator buckets:

    - In mining scenarios such as open-pit coal mines and metal mines, large excavators undertake a large amount of ore or rock and soil excavation work. The bottom plate, side plates, and cutting edge of the bucket are the most severely worn areas.

    - Bottom plate: Using wear-resistant plates (such as NM500 and above high-strength wear-resistant steel plates) laid on the bottom plate can effectively resist the intense friction and impact of ores and rock and soil during excavation, lifting, and unloading, prevent the bottom plate from wearing through too quickly, and ensure the bearing capacity and service life of the bucket.

    - Side plates: The side plates will be subject to scraping and collision from the excavated materials. Side plates made of wear-resistant plates can maintain their structural integrity and prevent deformation and damage, allowing the bucket to maintain a good working condition for a long time.

    - Cutting edge: The cutting edge directly cuts into the materials and needs to have high wear resistance and toughness. Using specially made wear-resistant alloy steel cutting edge plates or surfacing wear-resistant materials on the common cutting edge to form a wear-resistant layer can reduce the chipping and curling of the cutting edge, ensure the excavation efficiency and accuracy.

2. Small excavators and backhoe loader buckets (used for underground or small mine operations):

    - Although these types of equipment are relatively small, the buckets still face frequent material contact and wear. In underground ore excavation, roadway cleaning, and other work, the bucket walls, lip plates, and other parts of the bucket are reinforced with wear-resistant plates.

    - For example, using NM400 or so wear-resistant plates to make the bucket walls can reduce the wear caused by ore scraping; using composite wear-resistant materials with good wear resistance at the lip plate makes it more wear-resistant when inserted into the ore pile, helping to improve the operation efficiency and service life of the equipment in a limited space.

 II. Applications in transportation equipment

1. Mining dump truck carriages:

    - Mining dump trucks are responsible for transporting the mined ore from the mining area to the beneficiation plant, material yard, and other places. The carriages need to carry a large amount of heavy, hard-textured, and irregularly shaped ores.

    - Installing wear-resistant plate liners on the bottom and side walls of the carriage. Commonly used wear-resistant plate materials such as high-chromium cast iron wear-resistant plates and high-strength wear-resistant composite plates can significantly reduce the wear of the carriage by the ores during transportation, prevent perforation and deformation of the carriage, extend the maintenance cycle and overall service life of the carriage, and reduce transportation losses and safety hazards caused by ore spillage.

2. Underground mine cars:

    - Underground mine cars are used for short-distance transportation of ores and gangue and other materials in narrow roadways. The vehicle body and bucket of the mine car are also prone to wear.

    - By laying wear-resistant plates on the inner wall of the bucket, such as using wear-resistant ceramic composite plates, it can not only reduce the weight of the bucket but also effectively resist the friction and impact of the ores, ensure that the mine car can stably and reliably carry out multiple round-trip transports underground, improve transportation efficiency, and reduce maintenance frequency.

 III. Applications in crushing and screening equipment

1. Crushers:

    - Jaw crushers: The lining plates of the crushing cavity are the key vulnerable parts. When crushing ores by extrusion, the lining plates bear huge pressure and friction from the ores. Using high-manganese steel wear-resistant plates or new alloy wear-resistant plates to make the lining plates, with their good toughness and wear resistance, they can maintain long-term performance under high-stress environments, reduce the frequency of lining plate replacement, and ensure the stable crushing capacity of the crusher.

    - Cone crushers: The bowl liner and crushing wall and other parts of the cone crusher use lining plates made of wear-resistant plates. These lining plates need to have high hardness, high wear resistance, and good impact resistance. Like high-chromium cast iron wear-resistant lining plates are widely used in cone crushers and can adapt to the high-speed impact and grinding of ores to precisely crush the ores and improve the qualification rate of the product particle size.

    - Impact crushers: The impact plates and plate hammers are the parts that are prone to wear. Using wear-resistant plates to make the impact plates and using wear-resistant alloy materials to make the plate hammers can enable them to maintain good crushing performance under the repeated impact of the ores, extend the service life of the parts, and reduce the operating cost of the equipment.

2. Screening equipment:

    - Vibrating screen plates: Vibrating screens are used to screen the mined ores by particle size. The screen plates will be subject to continuous friction and impact during the jumping and rolling of the ores. Using polyurethane wear-resistant plates, stainless steel wear-resistant screen plates, etc., can improve the wear resistance and impact resistance of the screen plates, ensure the dimensional accuracy of the screen holes, make the screening effect more accurate and stable, and contribute to the precise development of the subsequent beneficiation process.

    - Screen frame of circular vibrating screens: The screen frame supports the screen mesh and will also be subject to the collision and wear of the ores. Using wear-resistant plates to reinforce it or manufacture the frame itself can enhance the stability and durability of the frame, prevent the screen mesh from loosening and deforming due to wear, and ensure the normal operation of the screening equipment.

 IV. Applications in conveying equipment

1. Belt conveyors:

    - Idlers: Idlers are the components that support the conveyor belt and reduce its running resistance. During the process of conveying ores, the surface of the idlers will have friction with the conveyor belt and the occasionally spilled ores. Using wear-resistant steel tubes or wear-resistant plates covered with wear-resistant rubber on the surface to make idlers can extend the service life of the idlers, reduce the wear of the conveyor belt, and improve the running stability of the belt conveyor.

    - Rollers: When the drive rollers and redirecting rollers drive the conveyor belt to operate, there is a large friction between them and the conveyor belt. Inlaying or covering the surface of the rollers with wear-resistant plates, such as ceramic rubber composite wear-resistant plates, can not only enhance the grip of the rollers, ensure the normal transmission of the conveyor belt, but also prevent the wear of the rollers themselves, ensuring the efficient and reliable conveying of ores by the belt conveyor.

    - Conveyor belts: For some special ore conveying requirements, such as when conveying high-hardness and sharp ores, a layer of wear-resistant plates or conveyor belts with wear-resistant coatings will be covered on the surface of the conveyor belt to enhance the wear resistance of the conveyor belt and reduce the occurrence of cuts, wear, and other damages.

2. Scraper conveyors:

    - Scrapers: Scraper conveyors are often used for short-distance conveying of coal and ores underground. The scrapers push the materials under the drive of the chain, and the friction with the materials and the middle trough is very intense. Using wear-resistant plates (such as high-strength wear-resistant alloy steel) to manufacture the scrapers can enable them to maintain good pushing ability under harsh working conditions, not easily deform or wear, and ensure the smooth conveying of materials.

    - Middle trough: The middle trough is the main bearing component of the scraper conveyor. The inner wall is installed with wear-resistant plate liners, which can reduce the friction loss between the scraper and the middle trough, prevent the middle trough from being worn through, maintain the conveying capacity of the scraper conveyor, and extend the overall service life of the equipment.

    - Chains: The chain links, chain plates, and other parts of the chains will also be worn due to the tension and friction with the materials. Using alloy wear-resistant plates with good wear resistance made of wear-resistant alloy steel to make the chain links or performing wear-resistant treatment on the chain plates can improve the strength and wear resistance of the chains, avoid chain breakage, and ensure the normal operation of the scraper conveyor.

3. Screw conveyors:

    - Screw blades: When screw conveyors are conveying powdery or granular ore materials, the screw blades are in continuous contact with the materials and push them forward, and are prone to wear. Using wear-resistant alloy steel or wear-resistant ceramic composite plates to make the screw blades can make the blades maintain good wear resistance during rotation, prevent the blades from thinning and breaking, and ensure that the materials can be conveyed in the set direction and speed.

    - Inner wall of the machine housing: The inner wall of the machine housing is also subject to the friction of the materials. Lining the inner wall of the machine housing with wear-resistant plates, such as wear-resistant plastic plates or wear-resistant rubber plates (selected according to the material characteristics), can reduce the wear of the machine housing, maintain a good conveying environment inside the screw conveyor, and improve the reliability of the equipment.

 V. Applications in grinding and separation equipment

1. Ball mills:

    - Cylinder liners: During the grinding process of the ball mill, the impact and friction of the steel balls and ores on the cylinder are very large. Using different types of wear-resistant plates such as rubber wear-resistant liners and magnetic wear-resistant liners as cylinder liners can not only protect the cylinder but also improve the grinding efficiency by using the characteristics of the liners through reasonable design. For example, rubber liners can play a buffering role, reduce the impact of the steel balls on the cylinder, and at the same time have certain wear resistance, extending the replacement cycle of the cylinder liners.

    - End cover liners: The end cover also requires wear resistance protection. Using end cover liners made of wear-resistant plates can withstand the impact and friction of the steel balls and ores, ensure the sealing and stable operation of the ball mill, and provide a strong guarantee for the grinding operation.

2. Flotation machines:

    - Inner wall of the agitation tank: During the agitation of the pulp in the agitation tank of the flotation machine, the ore particles and reagents in the pulp will cause scouring and corrosion to the inner wall. Using wear-resistant plates (such as stainless steel composite wear-resistant plates) that are resistant to wear and corrosion as the inner wall liners of the agitation tank can reduce the wear and corrosion of the inner wall, ensure the normal function of the agitation tank, facilitate the full contact of the flotation reagents with the ore particles, and improve the flotation effect.

    - Scrapers of the flotation tank: The scrapers of the flotation tank are used to scrape the flotation foam layer. During the working process, they will have friction with the tank wall and the pulp. Using scrapers made of wear-resistant plates can make them more durable, ensure that the scrapers scrape the foam in a timely and accurate manner, and improve the quality and recovery rate of the flotation products.

 VI. Applications in auxiliary equipment and facilities

1. Chutes and bunkers:

    - Chutes: Ores flow in the chutes by gravity, which will cause continuous friction and impact on the inner wall of the chutes, especially in cases of large height differences and large ore flow rates, the wear is more serious. Installing wear-resistant plate liners on the inner wall of the chutes, such as ultra-high molecular weight polyethylene wear-resistant plates, which have an extremely low friction coefficient and good wear resistance, can allow the ores to slide smoothly, reduce blockage and chute wear, and ensure the continuity of material transportation.

    - Bunkers: Whether it is the raw ore bunker or the intermediate product bunker, the loading, unloading, and accumulation of ores will cause wear to the bunker walls. Laying wear-resistant plates on the inner walls of the bunkers, such as wear-resistant ceramic patches or wear-resistant steel plates, can prevent the bunker walls from being worn through, maintain the structural stability of the bunkers, and ensure the safe storage and smooth discharge of the ores.

2. Pipeline systems:

    - Ore slurry transportation pipelines: During the ore beneficiation process, the ore slurry needs to be transported to different processing links through pipelines, and the inner wall of the pipeline will be scoured and friction by the solid particles in the ore slurry. Using pipelines with wear-resistant plate liners such as wear-resistant ceramic composite steel pipes and ultra-high molecular weight polyethylene lined steel pipes can effectively enhance the wear resistance of the pipelines, reduce pipeline blockage, leakage, and other problems, and ensure the smooth transportation of the ore slurry.

    - Tailings discharge pipelines: Tailings slurry is discharged to the tailings pond through pipelines. Due to the fine and large amount of tailings particles, the wear on the pipelines cannot be ignored. Using pipelines with excellent wear resistance (such as steel pipes lined with wear-resistant rubber) can extend the service life of the pipelines, reduce maintenance costs, and ensure that the tailings discharge meets environmental protection and safety production requirements.

3. Ventilation and drainage equipment:

    - Ventilation pipelines: In underground mining, ventilation pipelines need to transport air containing dust for a long time, and the dust will cause wear to the inner wall of the pipeline. Using galvanized wear-resistant steel plates, etc. to make ventilation pipelines or performing wear-resistant coating treatment on the inner wall of the pipeline can improve the anti-wear ability of the pipeline, ensure the normal operation of the ventilation system, and provide a good air quality environment for underground operations.

    - Drainage pumps and pipelines: During underground drainage, the water may contain impurities such as sediment. The impellers, pump casings of the drainage pumps, and drainage pipelines will all be subject to wear. Using wear-resistant alloy materials on the impellers and pump casings or installing wear-resistant plate protective layers, and using wear-resistant plastic plates for lining on the inner wall of the pipelines can enhance the wear resistance of the equipment and pipelines, ensure the stable and efficient operation of the drainage system, and avoid safety problems such as underground water accumulation caused by equipment failure.

In conclusion, wear-resistant plates have indispensable applications in every link of the mining industry. By improving the wear resistance of equipment and facilities, not only are their service lives prolonged and maintenance costs reduced, but also the efficient, safe, and sustainable operation of mining operations is guaranteed.
