Mining Conveyor Systems

In the production chain of the global mining industry (open-pit mines, underground mines, concentrators), the conveyance of bulk materials (ore, gangue, beneficiation tailings, etc.) faces challenges such as "high load, severe wear, heavy dust, and complex terrain". Relying on core equipment including long-distance belt conveyors, pipe belt conveyors, and radial telescopic stackers, as well as independently developed components like high-wear-resistant idlers, anti-corrosion rollers, and polyurethane cleaning scrapers, Zoomry Heavy Industry creates customized conveying solutions for the mining industry featuring "high load resistance + dust sealing + terrain adaptation".

Solution Advantages

Compared with other equipment in the industry, Zoomry's solutions focus on the core needs of the mining industry — "continuous production, harsh environments, and cost control" — and are well-suited for high-intensity mining operation scenarios in three dimensions: "load adaptability, environmental resistance, and full-lifecycle reliability":

1. High-Load Conveyance: To meet the high-flow material demands of mines, Zoomry's long-distance belt conveyors can achieve a conveying capacity of 500-2000 tons per hour (tph). The machine body adopts a high-carbon steel lattice frame, enabling stable operation even in complex terrains (e.g., open-pit mine slopes with a gradient ≤ 18°). Radial telescopic stackers are equipped with radial rotation, boom telescoping, and luffing adjustment functions; through optimized stockpiling design, they can increase stockpile capacity by over 28% compared with traditional fixed-length conveyors, meeting the large-scale ore stockpiling needs of mines;
2. Harsh Environment Resistance: All equipment and components comply with the ISO 9001 Quality Management System, ISO 14001 Environmental Management System, as well as CE (Europe) and EAC (Russia) certifications, enabling resistance to harsh mining environments such as dust, humidity, and heat. For example, independently produced idlers have a noise level of ≤ 40-45 dB (surpassing China's GB standard of 55 dB), an water ingress of ≤ 100g in the 72-hour immersion test (better than the GB standard of 150g), a radial runout of ≤ 0.4mm, and an IP65 protection rating — effectively preventing mining dust from entering and causing internal wear, with a service life exceeding 50,000 hours. Rollers are made of 40Cr forged material (diameter ≥ 159mm, suitable for wide belts) and undergo ultrasonic flaw detection and stress tempering treatment; their load-bearing capacity is 25% higher than that of ordinary rollers, enabling them to withstand the high-impact load of ore;
3. Full-Lifecycle Cost Optimization: Zoomry has built its own quality inspection center (including chemical laboratories, idler laboratories, etc., equipped with over 60 testing devices). Core components (idlers, rollers, cleaning scrapers) are independently produced with sufficient inventory, enabling fast supply within 48 hours and reducing equipment downtime. Meanwhile, efficiency is improved through "collaborative equipment design" — for instance, the combination of "long-distance belt conveyor + radial telescopic stacker" can shorten the ore "conveyance-stockpiling" cycle from 30 minutes (with traditional equipment) to 12 minutes, lowering the mining industry's production waiting costs.

Application Solutions for Segmented Scenarios in the Mining Industry

Focusing on three core scenarios of the mining industry — "open-pit mining, underground mine conveying, and concentrator material transfer" — and integrating material characteristics (e.g., large ore chunks in open-pit mines, fine tailings in underground mines, high-moisture materials in concentrators) and operating environments of each scenario, Zoomry develops targeted conveying systems to ensure seamless integration between bulk material conveyance and mining production processes:

Long-Distance Ore Conveyance and Stockpiling Solution

Open-pit mines need to transfer mined ore (particle size ≤ 500mm, density 2.8-3.5 t/m³) from the stope to the crushing plant or stockyard, with conveyance distances up to several kilometers. Most sites have complex terrains with undulating gradients, requiring equipment to have strong long-distance conveyance capabilities and terrain adaptability. Zoomry's solution centers on "long-distance belt conveyor + radial telescopic stacker" with wear-resistant design:

• Main Equipment Configuration: Select long-distance belt conveyors (belt width 1400-2000mm, conveying speed 2.5-3.0 m/s) with anti-corrosion coating treatment to adapt to the humid-hot or dry-dusty environment of open-pit mines. Match with ZR-SF Series Radial Telescopic Stackers, which feature radial rotation (360° adjustable), boom telescoping (maximum boom telescoping length 20m), and luffing adjustment (-15° to +25°). These functions allow flexible adjustment of stockpiling positions to avoid ore agglomeration, and increase stockpile capacity by over 28% compared with traditional fixed stackers;
• Component Assurance: Conveyor belts are made of tear-resistant polyester canvas material with a longitudinal tensile strength of ≥ 2000 N/mm, capable of withstanding the impact of large ore chunks. Idler sets adopt sealed double-row self-aligning spherical roller bearings with an IP65 dust and water protection rating, reducing wear caused by dust intrusion. The inner wall of chutes is equipped with 12-15mm thick wear-resistant alloy liners to prevent chute deformation due to ore impact, extending the service life to over 8 years;
• Application Advantages: This solution enables 24/7 continuous conveyance in open-pit mines, with monthly equipment downtime controlled within 2 hours. Compared with the traditional dump truck transfer mode, it reduces transportation costs by 60%. Additionally, through the flexible stockpiling design of the telescopic stacker, the ore stockpiling loss rate is reduced from 5% (with traditional equipment) to 1.2%, effectively improving the mine's resource utilization rate.

Sealed Conveyance Solution for Fine Tailings and Ore

Underground mines (e.g., metal mines, coal mines) need to convey fine tailings (particle size ≤ 0.1mm) or crushed ore. The working space is narrow (tunnel width ≤ 5m) with high dust concentration; material leakage must be avoided to prevent underground environmental pollution and protect the health of workers. Zoomry's solution centers on "pipe belt conveyors" to build a sealed conveying system:

• Main Equipment Selection: Pipe belt conveyors are preferred. The conveyor belt is folded into a tubular structure (supported by 6 sets of idlers forming a hexagon), achieving 100% sealed conveyance of materials and preventing the diffusion of fine tailings. With a maximum turning angle of 110° (far exceeding the 70° of ordinary belt conveyors), they can flexibly bypass underground tunnel corners without the need for additional transfer platforms, reducing the occupation of underground installation space;
• Safety and Environmental Design: The equipment is equipped with belt deviation switches and pull cord switches. When the conveyor belt deviates or malfunctions, it can stop immediately to ensure underground operation safety. A non-powered dust-collecting chute is installed at the discharge end to further reduce dust overflow through airflow buffering, controlling the underground dust concentration below 8mg/m³ and complying with mainstream global mining safety and environmental standards;
• Application Advantages: In underground mine applications, this solution enables leak-free conveyance of fine tailings, reducing dust pollution by 90% compared with traditional open belt conveyors. The compact machine body is suitable for narrow underground spaces, and the conveying efficiency is 30% higher than that of traditional equipment, effectively reducing the dust exposure risk for underground workers.

Crushed Ore and Tailings Handling Solution

Concentrators need to convey crushed ore (particle size 5-50mm) to the flotation workshop while handling high-moisture tailings (moisture content 20%-30%). Materials tend to adhere to equipment and cause clogging, requiring equipment to have anti-clogging and high-efficiency cleaning capabilities. Zoomry's solution centers on "truck unloader + hopper feeder" with anti-clogging and cleaning devices:

• Main Equipment Collaboration: Adopt ZRLS-TU Series Truck Unloaders (wheeled or tracked options, belt width 1400-1800mm, conveying capacity 600-1800 tph) equipped with 2-4 lane unloading ramps, supporting simultaneous unloading of multiple ore transport trucks to avoid vehicle queuing and congestion. After unloading, hopper feeders (with customized 3.5-5.7m wide receiving hoppers) provide stable feeding; the bottom of the hopper is equipped with a vibration device to prevent clogging caused by adhesion of high-moisture tailings, with a feeding error of ≤ ±2%;
• Cleaning and Anti-Clogging Assurance: One set of polyurethane (PU) cleaning scrapers is installed at both the head and tail of the belt conveyor, combined with an optional set of brush cleaning devices, achieving a cleaning efficiency of over 98% and reducing conveyor belt deviation caused by material adhesion. The inner wall of the hopper is lined with polytetrafluoroethylene (PTFE) to reduce tailings adhesion. Meanwhile, impact beds (replacing traditional buffer idlers) are equipped to reduce the impact damage of falling crushed ore on the conveyor belt;
• Application Advantages: This solution enables the integration of "truck unloading - stable feeding - clean conveying" in concentrators. The material clogging rate is reduced from 8% (with traditional equipment) to 0.5%, and the cycle of conveying crushed ore to the flotation workshop is shortened from 15 minutes (with traditional equipment) to 6 minutes, effectively accelerating the concentrator's production rhythm. Additionally, the annual maintenance cost of the equipment is 35% lower than that of traditional equipment.
