ZR80SF Stacker conveyor

The ZR80SF Stacker Conveyor is the core model of ZOOMRY focusing on small and medium-sized bulk material stockpiling. Equipped with an 800mm-wide belt, it achieves a maximum handling capacity of 500m³/h at a belt speed of 2.50m/s. Combined with a 10-22m telescopic boom, as well as radial rotation and luffing lifting functions, it can accurately control the entire stockpiling process of bulk materials such as coal and ore, fundamentally avoiding issues of material segregation, degradation, contamination, and compaction. It supports transportation via 40-foot high cube containers (HQ), and on-site installation can be completed within 10-20 days after pre-assembly. With international certifications including CE, EAC, and KCS, it is a reliable choice for scenarios such as small and medium-sized berths in ports and medium-sized stockyards in the mining industry.

Core Functions of ZR80SF Stacker Conveyor

The core competitiveness of the ZR80SF Stacker Conveyor stems from its in-depth insight into the needs of bulk material stockpiling scenarios. Through the synergistic effect of three major functions—"radial rotation, telescopic adjustment, and luffing lifting"—it fundamentally solves the problems of limited operation and high material loss of traditional stockpiling equipment.

Radial Rotation

The equipment is equipped with a hydraulically driven radial rotation system, enabling 360° dead-angle-free stockpiling operations (the maximum steering angle can reach 110° depending on on-site working conditions, far exceeding the 70° limit of ordinary belt conveyors). In port bulk cargo terminals or mining stockyards, there is no need to frequently move the main body of the equipment; instead, materials can be evenly stockpiled in different areas through radial rotation. This significantly reduces the time for equipment displacement, improves site utilization, and is particularly suitable for scenarios requiring alternate stockpiling in multiple areas.

Telescopic Adjustment

The telescopic boom of the equipment adopts a high-strength lattice frame structure, and its length can be flexibly adjusted according to stockpiling needs (standard telescopic range: 15-25 meters, with support for customized extension). When handling small batches of materials, shortening the telescopic boom can reduce no-load energy consumption; when handling large batches of materials, extending the telescopic boom can avoid compaction caused by excessively high material accumulation. At the same time, the telescopic system is equipped with a dedicated "curtain-type" cable sliding device, ensuring no jamming or wear of cables during the telescopic process, and its service life is 50% longer than that of ordinary sliding systems in the industry.

Luffing Lifting

The luffing mechanism is driven by a hydraulic cable system, enabling precise adjustment of the stockpiling height within the range of 6.5-8.0 meters (it automatically adapts according to the angle of repose of materials; for example, under the working condition of kaolin with a 45° angle of repose, the stockpiling height can reach 8 meters, and the optional configuration allows a maximum stockpiling height of 20 meters). In ore stockpiling scenarios, controlling the material falling height through luffing lifting can effectively reduce material degradation caused by impact (e.g., the degradation rate of limestone is reduced from 5% of traditional stockpiling to less than 1%), while preventing dust from flying, which meets environmental protection requirements.

In addition, through the coordinated control of various functions, the ZR80SF Stacker Conveyor can completely eliminate the four core problems in bulk material stockpiling: material segregation (uniform distribution of materials with different particle sizes), degradation (reduction of impact crushing), contamination (prevention of external impurities from mixing in through sealed stockpiling), and compaction (reduction of bottom pressure through layered stockpiling). This ensures stable material quality, making it particularly suitable for industries such as cement and ore that have high requirements for purity.

Core Components

Drive and Hydraulic System

The drive system can optionally adopt well-known brand gear motors such as SEW (Germany), FLENDER (Germany), and JlE (China), with an output power of 22kW (main conveyor) + 11kW (chassis), which is suitable for handling requirements of 300TPH. The motor efficiency is over 95%, saving 10% more energy than ordinary motors. The hydraulic power pack adopts a high-quality hydraulic system, with an oil tank capacity of 500-650 liters and a dual filtration device. The hydraulic oil cleanliness reaches NAS Class 8, which reduces wear of hydraulic components, and the annual system failure rate is less than 0.5%.

Control System

The equipment supports three operating modes and is equipped with an HMI touch screen. The operation interface is simple and intuitive, supporting multi-language switching to facilitate operation and maintenance by customers in different regions, meeting the needs of different scenarios:

1. PLC Fully Automatic Mode: The stockpiling process is automated through a programmable logic controller. Stockpiling paths (such as "circular stockpiling" and "layered stockpiling") can be preset, and radial, telescopic, and luffing parameters can be automatically adjusted, reducing manual intervention and lowering labor costs;
2. Remote Control Mode: Equipped with a wireless remote control, the operation distance can reach 50 meters, allowing operators to observe the material stockpiling situation on-site and make real-time adjustments;
3. Manual Mode: It can be switched to manual operation in emergency situations to ensure the controllability of the equipment.

Safety System

The ZR80SF Stacker Conveyor fully covers risk scenarios such as "power failure, rope breakage, and belt deviation" in its safety design: In case of power failure, the hydraulic cable system automatically self-locks within 0.01 seconds to prevent the telescopic boom from suddenly falling; it is equipped with dual mechanical limit devices, so even if the steel wire rope breaks, the telescopic boom will be locked by the limit mechanism to avoid the expansion of accidents; Tilt switches are installed on both sides of the belt, and when the belt deviation exceeds the set value, the equipment automatically shuts down to prevent belt wear or material spillage.

Cleaning and Maintenance Components

The head and tail of the equipment are each equipped with a set of polyurethane (PU) cleaning scrapers, totaling 4 sets (for 3-phase power supply configuration), with a cleaning rate of 98%. They can effectively remove residual materials on the belt surface and reduce belt wear. The service life of the scrapers reaches 10,000 hours, and they can be replaced individually, resulting in low maintenance costs. For ultra-heavy stockpiling scenarios, bilateral maintenance walkways can be added, with a load-bearing capacity of 200kg/㎡, facilitating engineers' inspection and maintenance and complying with safety standards.

Convenient Transportation and Efficient Installation

Controlling Logistics Costs

The main structure of the equipment has undergone lightweight optimization. All core components can be disassembled and loaded into 40-foot high cube containers (HQ), without the need for special transportation tools (such as ultra-wide or ultra-high trucks), reducing cross-border logistics costs. It also avoids the application process for special transportation permits, shortens the logistics cycle, and facilitates the rapid progress of projects.

On-Site Installation in 10-20 Days

Before leaving the factory, the equipment has completed 80% of the pre-assembly work. On-site, only simple processes such as telescopic boom docking, hydraulic system commissioning, and electrical wiring need to be completed. ZOOMRY provides a detailed installation guide manual and can send engineers to supervise the installation on-site. According to historical project data, a skilled team can complete installation and commissioning in as fast as 10 days, and no more than 20 days at the slowest, which is 1/3 shorter than the industry average installation cycle of 30 days, helping customers achieve production quickly.

Adapting to Multi-Market Standards

As a core product for the global market, the ZR80SF Stacker Conveyor has obtained compliance certifications from multiple mainstream markets, ensuring legal use in different countries and regions and reflecting ZOOMRY's international compliance capabilities. It meets the EU CE certification (Machinery Directive 2006/42/EC and Electromagnetic Compatibility Directive 2014/30/EU), Russian Customs Union EAC certification, and South Korean KCS certification. At the same time, it fully complies with the requirements of the ISO 9001 Quality Management System and ISO 14001 Environmental Management System.

Core components (such as idlers and rollers) have passed the testing of CEMA (Conveyor Equipment Manufacturers Association, USA) standards. ZOOMRY's self-built quality testing center (including a chemical laboratory, hardness laboratory, idler performance laboratory, etc.) is equipped with more than 60 testing devices. Each ZR80SF Stacker Conveyor must undergo 12 rigorous tests (such as load testing, noise testing, and hydraulic system tightness testing) before leaving the factory to ensure stable and reliable quality.

Application Scenarios

With its flexible operation performance and stable handling capacity, the ZR80SF Stacker Conveyor is widely used in two core scenarios—ports and mining—solving bulk material stockpiling needs under different working conditions.

In the scenario of port bulk cargo terminals, the equipment is mainly used for stockpiling bulk materials (such as coal, iron ore, and grains) after unloading, and is particularly suitable for terminals with limited space. Through radial rotation and telescopic adjustment, it can maximize the use of terminal space. Combined with the sealed stockpiling design, it reduces dust emission and meets the environmental protection requirements of ports.

In the scenario of mining stockyards, the equipment can handle heavy bulk materials such as iron ore, limestone, and coal (with a maximum handling capacity of 300TPH) and is suitable for complex terrains. An optional tracked tail section allows flexible movement even on muddy and rough mining ground, preventing the equipment from getting stuck. By controlling the material falling height through luffing lifting, it reduces the degradation of high-hardness ores and ensures subsequent processing efficiency.
