In the field of bulk material conveying, "complex terrain" has always been an industry pain point. Whether it is the steep slope drop in mountain mining, cross-water connection in ports and terminals, or disconnected scenarios involving tunnels and residential areas in infrastructure projects, traditional single or a small number of feeding equipment often faces problems such as low conveying efficiency, high material loss, and difficult equipment coordination. When enterprises need to handle large-scale bulk materials (e.g., 10,000-ton daily capacity mines, port loading operations), the scientific configuration and linkage of hopper feeders can solve the difficulty of conveying in complex terrain.
The biggest challenge of complex terrain is "spatial barriers": In mountain mining areas, stope and stockyard are often separated by steep slopes and canyons, making a single hopper feeder unable to cover long-distance conveying of more than 3 kilometers; In ports and terminals, there is a height difference between the unloading area and loading area, and traditional fixed hopper feeders cannot flexibly adjust the height; In scenarios involving tunnels or residential areas, equipment needs to balance "miniaturization" and "large flow", and a single type of equipment cannot achieve this balance. Although ZOOMRY's pipe belt conveyors can achieve 110° turns (far exceeding the 70° of ordinary belt conveyors), they need to be matched with multiple hopper feeders to realize "segmented connection" and avoid link interruption.
During the conveying of bulk materials (such as coal, ore, aggregates) in complex terrain, three types of problems are likely to occur due to "uneven flow rate": First, material stratification, which leads to fluctuations in downstream processing quality; Second, dust emission and leakage, which do not comply with EU EN 15237 or China's GB environmental standards; Third, equipment wear, for example, excessive material impact in steep slope sections shortens the service life of idlers and rollers. ZOOMRY has statistically found that the material loss rate of traditional single hopper feeder solutions can reach 5%-8%, and the noise often exceeds 60dB, which is likely to cause complaints around residential areas. This is inconsistent with the adaptation requirements of ZOOMRY's silent idlers (noise ≤45dB, better than the 55dB required by GB standards), and also highlights the necessity of "buffer adjustment with multiple hopper feeders".
ZOOMRY's target customers cover the global market, and overseas projects need to comply with multiple standards such as CE (Europe), EAC (Russia), and CEMA (North America). For example, European projects require equipment to have an "emergency self-locking function", Russian projects need to withstand -30℃ low temperature, and North American projects need to comply with CEMA's idler precision standards (axial displacement < 0.5mm). In traditional solutions, if a single hopper feeder wants to meet multi-regional compliance, parameters need to be adjusted repeatedly, which not only costs a lot but also easily leads to the problem of "adapting to one place but not another". However, ZOOMRY's hopper feeders can be customized based on certification requirements (e.g., CE-certified models are equipped with overload protection, EAC-certified models have enhanced low-temperature performance), laying a foundation for the coordination of multiple units.
Not all complex terrains require multiple hopper feeders. ZOOMRY's solution design needs to go through three pre-steps: "terrain survey - material analysis - compliance alignment" to ensure that the number and configuration of equipment accurately match the needs and avoid "blind accumulation".
ZOOMRY's technical team adopts a combination of "drone scanning + on-site surveying and mapping" to obtain three core types of data:
ZOOMRY usually divides 10 hopper feeders into "Front-end Feeding Group (3 units), Transfer Buffer Group (4 units), and Back-end Discharging Group (3 units)". The function of each group directly corresponds to the terrain pain points:
Group | Quantity | Core Function | Adapted Terrain Pain Points | Key Configuration (Based on ZOOMRY Equipment) |
---|---|---|---|---|
Front-end Feeding Group | 3 units | Connect with truck unloaders/crushers and evenly distribute materials to the main conveyor | "Instant large feeding volume" in stopes to avoid material blocking | Hopper capacity 10-15m³, conveying capacity 200-500 TPH, matching ZOOMRY's ZRLS-TU1400 truck unloader (belt width 1400mm) |
Transfer Buffer Group | 4 units | Transfer across steep slopes/tunnels and adjust material flow rate | "Large impact" on steep slopes, "narrow space" in tunnels | Crawler chassis (anti-subsidence), foldable hopper body (adapted to tunnels), connected to pipe belt conveyors (110° turn) |
Back-end Discharging Group | 3 units | Connect with mobile stackers/ship loaders and precisely control the discharge volume | "Large height difference" in ports, "flexible adjustment required" for stacking | Adjustable discharge speed (0.5-2.5m/s), adapted to ZOOMRY's ZR-SF radial telescopic stacker (stacking height ≤20m) |
The advantage of this layout is that the 3 front-end units solve the problem of "uneven feeding", the 4 transfer units solve "terrain barriers", and the 3 back-end units solve "discharging adaptation", forming a closed-loop full link.
The biggest risk of multiple equipment units is "asynchrony". If the front-end feeding is too fast and the back-end processing is not timely, it is easy to cause material blocking in the transfer section; If the front-end feeding is too slow, it will cause material interruption at the back-end. ZOOMRY solves this problem through the "PLC+HMI" control system, whose core functions include:
The efficient operation of 10 hopper feeders requires in-depth adaptation to ZOOMRY's conveying equipment and core components to maximize the solution of complex terrain pain points:
ZOOMRY provides "5-year warranty + quarterly inspections" for this project. Core components (idlers, rollers) can be replenished within 72 hours through the overseas spare parts warehouse (Southeast Asia Warehouse), and the equipment has been in operation for 18 months without major faults.
In summary, the core of "how to use 10 hopper feeders for bulk material conveying in complex terrain" is not simply explaining equipment operation, but presenting a complete logic from "pain point analysis to solution derivation, and then to implementation verification". First, through three preparations (terrain, material, compliance), the necessity of configuring 10 units of equipment is determined; Then, through group layout, linkage control, and supporting adaptation, complex terrain pain points are solved in a targeted manner; Finally, the feasibility and value of the solution are verified through practical cases.
