In the global bulk material handling industry, the rough terrain of mines, the demand for multiple ship types in ports, and the differences in material characteristics of sand and gravel yards have plunged enterprises into a dilemma of "difficult equipment selection, high costs, and low efficiency". If specialized transfer equipment is configured for mines, it is necessary to replace it with a shiploader when moving to ports. This not only incurs high initial investment but also results in a daily operating hour reduction of 2-3 hours due to downtime during equipment switching and connection. To address this industry pain point, ZOOMRY has developed the ZRSL Series—fully adaptable mobile shiploaders for mines and ports. With the core advantages of "one machine covering multiple scenarios and function switching on demand", it breaks the scenario limitations of traditional equipment.

Core Issues in Bulk Material Conveying

Cost Pressure

Under the traditional bulk material handling model, enterprises need to configure fixed conveyors for mine transfer, specialized shiploaders for port loading, and stackers for sand and gravel yard stockpiling. The total investment in these three types of equipment is more than 65% higher than that of a single fully adaptable shiploader, and the equipment idle rate can reach 30% (e.g., port shiploaders have no use scenarios during mine off-seasons). Through its "modular component design", ZOOMRY's ZRSL Series mobile shiploader can switch scenarios by replacing only local accessories (such as wear-resistant liners and Conveyor Belts). A single piece of equipment replaces three types of traditional equipment, directly reducing initial procurement costs by 40%-50% while reducing equipment storage space occupation (saving approximately 60% of warehouse space).

Efficiency Bottlenecks

Most of the "efficiency loss" in bulk material handling stems from equipment connection. Taking the transfer of mine ore to ports for loading as an example, the traditional process first transports ore to transfer silos via fixed conveyors (taking about 1 hour), then transfers it to shiploaders via loaders (taking about 40 minutes). The cumulative downtime loss during intermediate connection reaches 1.5-2 hours per batch. Relying on its "crawler-type mobile chassis + telescopic boom", ZOOMRY's ZRSL Series mobile shiploader can travel directly from the mine stope to the port terminal (maximum travel speed of 5 km/h), enabling continuous conveying throughout the process without interruptions. The material processing efficiency per batch is increased by 30%. Moreover, core components (rollers, idlers) adopt a wear-resistant design, with a fault-free operation time of over 8,000 hours, reducing downtime caused by equipment maintenance.

Difficulty in Scenario Adaptation

• Mine Scenarios (Coal Mines, Metal Mines): Need to cope with the impact of large-particle materials (e.g., lump coal in coal mines can have a particle size of up to 150 mm) and wet, muddy terrain. The equipment uses 12 mm-thick wear-resistant liners (hardness up to HRC58-62) and anti-slip crawlers (ground pressure ≤80 kPa) to prevent material wear and vehicle getting stuck.
• Port Scenarios (Bulk Terminals, Container Ports): Need to adapt to the demand for multiple ship types, from 100-ton barges to 120,000-ton cargo ships. The equipment's boom is telescopic (maximum extension length of 15 meters) with an adjustable discharge height (3-22 meters). Its sealed conveying structure ensures dust emission ≤35 mg/m³, complying with EU CE, US EPA, and other environmental standards.
• Sand and Gravel Aggregate Scenarios: Need to solve the material blocking issue caused by high moisture content (15%-25%). The equipment's hopper is equipped with built-in "anti-blocking guide plates", and combined with a frequency-adjustable conveyor belt (speed 0.8-2.5 m/s), it can adjust the conveying speed in real time according to the moisture content of sand and gravel, reducing the material blocking failure rate to below 2%.

ZOOMRY Fully Adaptable Mobile Shiploader

One-Click Adaptation for Shiploading, Transfer, and Stockpiling

The equipment has three built-in core working modes, which can be switched with one click via the HMI intelligent operation screen:

• Shiploading Mode: The boom extends above the ship's cargo hold, equipped with a "precision discharge control system" (error ≤500 mm). It can automatically adjust the material distribution trajectory according to the cargo hold size, avoiding cargo hold unbalance caused by material accumulation.
• Transfer Mode: The crawler moves between the raw material pile and the target point. The conveyor belt has a maximum inclination angle of 18 degrees, enabling "point-to-point" direct transfer (e.g., from mine stope to mineral processing plant, port transfer silo to terminal) and replacing traditional fixed conveyors.
• Stockpiling Mode: The boom can rotate 360 degrees (steering angle ≤110 degrees). Combined with a layered stockpiling algorithm, it forms regular material piles (maximum pile height up to 22 meters), reducing material segregation. The stockpiling capacity is 25% higher than that of traditional stackers (for a 50-meter equipment, the kaolin stockpiling capacity reaches 101,275 tons).

Customized Components

Targeting the physical properties of different bulk materials, the equipment can be customized with core components to ensure adaptability:

• Wear Resistance Requirement (Ore, Coal): The hopper and chute are equipped with wear-resistant ceramic liners (thickness 8-12 mm), whose service life is 3 times longer than that of ordinary steel plates, reducing liner replacement costs by approximately 50,000 yuan per year.
• Anti-Adhesion Requirement (Cement, Fly Ash): The surface of the conveyor belt is coated with a Teflon anti-adhesion layer, combined with a "double scraper cleaning system" (scraping rate ≥98%), avoiding belt deviation caused by material residue.
• Explosion-Proof Requirement (Coal Mines): The motor and control system adopt an Ex d IIB T4 Gb explosion-proof design, equipped with a gas concentration detection sensor (detection range 0-100% LEL), eliminating safety hazards in underground coal mine operations.

Intelligent and Efficient

The equipment is equipped with an industrial-grade PLC control system and a 10.1-inch touchscreen, realizing full-process automation:

• Automatic Parameter Adaptation: After inputting the material type (e.g., iron ore, sand and gravel) and scenario mode (shiploading/transfer/stockpiling), the system automatically adjusts the belt speed, boom angle, and discharge height without repeated manual debugging.
• Remote Monitoring and Maintenance: Supports remote monitoring via mobile APP (compatible with Android/iOS) and computer terminal, enabling real-time viewing of equipment operation data (belt speed, motor temperature, fault early warning). One maintenance personnel can manage 2-3 devices, reducing labor costs by 60%.
• Multiple Safety Protections: Equipped with 7 safety devices including power-off self-locking (response time ≤0.01 seconds), overload protection, steel rope breakage limit, and emergency stop button, avoiding operational risks during scenario switching.

Global Compliance

To meet regulatory requirements in different regions worldwide, the equipment has obtained multiple international authoritative certifications:

• Quality System Certifications: ISO 9001 Quality Management System (ensuring production consistency), ISO 13485 Medical Device-Grade Quality Standard (high-precision component control).
• Environmental Certifications: ISO 14001 Environmental Management System, EU CE Certification (dust emission and noise control comply with European EN 12001 standard), Korean KCS Certification (adapting to Korean port environmental requirements).
• Safety Certifications: US OSHA Safety Standard (complying with North American industrial safety regulations), Australian AS 4024 Machinery Safety Standard (adapting to the Oceania market), ensuring barrier-free implementation of overseas projects.

Low Consumption and Durability

The equipment balances "energy efficiency" and "durability" in design, reducing long-term operation and maintenance costs:

• Dual-Power Energy Saving: Supports dual-power switching between diesel (Yuchai YC6A series engine, fuel consumption ≤25 L/h) and electricity (380 V/50 Hz three-phase electricity). In scenarios with municipal power such as ports, electric drive is used, reducing energy consumption by 40%.
• High-Specification Components: The roller shaft is made of 40Cr forging (diameter ≥200 mm), undergoing ultrasonic flaw detection and quenching-tempering treatment (hardness HB220-250); the idler adopts an HDPE shell + silent bearing (noise ≤45 dB), with a service life of over 50,000 hours.
• Extended Warranty: Provides a 5-year warranty for the main equipment and a 2-year warranty for vulnerable parts (the industry average warranty period is 3 years). Free spare part replacement and technical support are provided within the warranty period, reducing maintenance costs.

Project Application Cases

Cross-Scenario Handling in an Iron Ore Mine

An iron ore mine located in a rainy mountainous area (annual rainfall 1200 mm) needed to transfer stope ore (particle size 50-100 mm) to a mineral processing plant 2 kilometers away, and then ship the concentrate for export. The traditional mode used "fixed conveyors + shiploaders" with an equipment investment of millions of yuan, and fixed conveyors were prone to deviation due to foundation settlement in the rainy season, resulting in 2-3 days of downtime per month. After selecting the ZRSL-50 model (equipped with anti-slip crawlers with ground pressure 75 kPa and waterproof motors), the equipment could move directly from the stope to the mineral processing plant with a transfer efficiency of 1200 tph; during shiploading, the boom extended to an 80,000-ton cargo ship with a discharge error ≤300 mm. After project commissioning, the equipment investment was reduced to 1.6 million yuan, no downtime was recorded in the rainy season, the concentrate shiploading efficiency was increased by 28%, and the annual operation and maintenance cost was saved by 200,000 yuan.

Coal Mine Transfer + Shiploading

A coal mine located on the Loess Plateau (terrain slope 15 degrees) needed to transfer raw coal from the stope to the downhill terminal for shiploading. The traditional process required the cooperation of "loaders + fixed conveyors + shiploaders" with a per-batch processing time of 4 hours and excessive coal dust emission (≥80 mg/m³). After selecting the ZRSL-45 model (equipped with explosion-proof motor + sealed belt), the equipment could drive directly from the stope to the terminal, the belt was inclined at 12 degrees during transfer (throughput 800 tph), and the dust emission was ≤30 mg/m³ during shiploading. After project commissioning, the per-batch processing time was shortened to 2.5 hours, labor costs were reduced by 60%, and environmental fines of approximately 150,000 yuan were avoided annually.

Sand and Gravel Aggregate Stockpiling + Loading

A sand and gravel yard had a daily processing capacity of 12,000 tons of sand and gravel. Traditional stackers could only stockpile, requiring additional loaders (investment of 600,000 yuan), and frequent material blocking occurred when the sand and gravel had high moisture content (20%) (3-4 times per day). After selecting the ZRSL-40 model (equipped with anti-blocking guide plates + frequency-adjustable belt), the boom rotated 360 degrees to form a 12-meter-high material pile during stockpiling, and moved directly above the truck during loading (discharge height 3-5 meters), with the belt speed adjusted according to moisture content (1.2-2.0 m/s). After equipment commissioning, the loader investment was eliminated, the material blocking failure rate was reduced from 15% to 1.5%, the daily operating hours were increased by 2 hours, and the annual production capacity was increased by 15%.
