Core Advantages of the Spiral Scraper Conveyor
The core competitiveness of the ZOOMRY Spiral Scraper Conveyor lies in three key dimensions: “full capacity coverage, multi-scenario adaptability, and low-loss operations.” Addressing the critical pain points in bulk material handling—such as “diverse material types, variable operating environments, and significant scale differences”—it resolves the issues of traditional scraper equipment, including “fixed capacity, poor material adaptability, and complex operation,” through structural optimization and functional integration, while meeting clients’ dual expectations for equipment versatility and reliability.
The spiral scraper system adopts a composite design of “alloy teeth + wear-resistant blades.” The 6-8 mm thick blades are inlaid with high-strength alloy teeth on the outer side, offering 1.2 times higher wear resistance than ordinary carbon steel blades, capable of withstanding long-term impact and wear from hard bulk materials like gravel and ore. The spiral outer diameter ranges from 500-800 mm, paired with a scraping width of 2-3.2 m and a material pickup width of 2.4-3.6 m, allowing flexible adjustment of scraping efficiency based on material pile density: for lightweight bulk materials like grain, the large-diameter spiral enables high-capacity output; for medium-heavy materials like coal, the medium-to-small diameter spiral with alloy teeth allows precise speed control to avoid overloading; for blocky bulk materials, the alloy teeth can break up slight caking, ensuring continuous scraping without clogging. Additionally, the spiral system features an “adaptive pressure adjustment” function, automatically adjusting speed and scraping depth when encountering oversized materials to prevent component damage from hard impacts, while feeding material resistance data to the HMI screen via sensors to assist operators in optimizing operational parameters and reducing failure risks.
The dual-configuration tracked chassis ensures adaptability to different terrains: the rubber tracks, model 4009068 with an effective length of 2.9 m, are made of high-elasticity wear-resistant material with a ground pressure of only 0.07 MPa, suitable for soft ground operations such as mine tailings or grain storage yards, preventing equipment entrapment while minimizing damage to ground infrastructure. The steel tracks, model 40013554 with an effective length of 3.6 m, have carburized and quenched track plates with a hardness of HRC58-62, improving wear resistance by 80%, ideal for rough, hard surfaces like gravel yards in construction material plants or mining areas, resisting scratches from sharp materials and extending chassis lifespan. Both chassis types are driven by hydraulic motors paired with planetary reducers, delivering an output torque of up to 3500 N·m, enabling smooth steering and movement even under full load. The standard chassis outer width is 2.3 m, with customizable widening options to further enhance stability on complex terrains.
The dual-mode control system is fully adapted to dusty and rainy outdoor environments: the stainless steel rainproof control cabinet, made of 304 stainless steel with an IP65 protection rating, effectively resists water and dust intrusion, with internal components sourced from internationally renowned brands to ensure long-term stable operation. The wireless remote control handle, with an effective range of 100 meters, supports full equipment functionality, including one-touch start/stop, spiral speed adjustment, chassis movement, and Conveyor Belt start/stop, allowing operators to monitor operations from a safe distance without direct contact with bulk materials, significantly enhancing operational safety and convenience. Additionally, the control system features an “operation memory” function, capable of storing three sets of commonly used operational parameters, such as spiral speed and conveyor belt speed, enabling one-touch retrieval when switching material types, eliminating the need for repeated adjustments and improving operational efficiency. The system also includes multiple safety protections: in emergencies, both the remote handle and control cabinet have emergency stop buttons that immediately cut off all power; the spiral and conveyor belt have overload protection, automatically stopping and alarming when the load exceeds the rated value; the control cabinet includes built-in temperature and humidity sensors, triggering audible and visual alarms when environmental parameters exceed normal ranges (temperature -20℃ to 60℃, humidity <90%), alerting operators to take timely protective measures.
Core Components of the Spiral Scraper Conveyor
The long-term reliability of the ZOOMRY Spiral Scraper Conveyor stems from the targeted optimization of core components for “wear resistance, adaptability, and ease of maintenance.” Each component undergoes multi-condition simulation testing at ZOOMRY’s quality testing center, ensuring compliance with the long-term operational needs of various bulk material types and environments.
The drive unit of the spiral scraper system employs high-power motors, with power configured based on capacity gradients: 22-37 kW for low-capacity operations (100-500 tph), 45-55 kW for medium-capacity operations (500-1200 tph), and 75 kW for high-capacity operations (1200-2000 tph). With a motor efficiency exceeding 95.5%, it offers superior energy savings compared to standard motors, and its IP55 protection rating ensures resistance to dust and moisture in outdoor environments. The accompanying reducer offers three models: ZQ350 dual output, ZQ400 dual output, and ZLY250 hard-tooth surface dual output, all with transmission efficiencies above 97%. The hard-tooth surface reducer provides 50% higher load-bearing capacity than standard models, capable of withstanding instantaneous impact loads during spiral scraping, extending the overall lifespan of the drive system. The spiral blades and teeth adopt a modular design, allowing individual replacement of worn parts without dismantling the entire spiral shaft, reducing maintenance time to within 2 hours. The teeth are bolt-fixed, requiring simple tools for replacement, enabling clients to perform maintenance without professional engineers.
The conveyor belt system covers a bandwidth range of 800-1600 mm, flexibly matched to capacity and material block size: 800-1000 mm bandwidth for small-to-medium capacity operations (100-800 tph), and 1200-1600 mm for high-capacity operations (800-2000 tph). The conveyor belt is made of nylon-core anti-slip rubber with a longitudinal tensile strength of 1600 N/mm, featuring an 8 mm deep diamond-patterned surface treatment that enhances anti-slip performance by 40%, effectively preventing material slippage during transport, especially for wet coal or sticky gravel. The conveyor belt is driven by a 15-30 kW electric drum, eliminating the need for additional motor and reducer installations, offering a compact structure and easy maintenance. The electric drum has an IP54 protection rating with built-in overheat protection, automatically stopping at temperatures above 120℃ to prevent burnout risks. The conveyor belt’s fixed discharge height of 4 meters matches the feed height of common trucks and conveyors, ensuring rapid material transfer with minimal spillage loss.
The hydraulic and chassis system’s core is an 11-18.5 kW hydraulic pump station, flexibly matched to chassis type and spiral specifications: 11 kW for rubber tracked chassis, and 15-18.5 kW for steel tracked chassis and large spiral specifications. The pump station has a 200 L oil tank equipped with dual filtration devices with a filtration accuracy of 10 μm, achieving a hydraulic oil cleanliness level of NAS 8, reducing wear on hydraulic components and maintaining an annual system failure rate below 0.5%. The hydraulic pipelines use high-pressure hoses with a working pressure of 30 MPa and stainless steel connectors, offering excellent corrosion resistance suitable for dusty and salt-spray environments. The chassis travel system, linked with the hydraulic motor, supports stepless speed regulation with a travel speed of 0-3 km/h, adjustable to operational needs. The chassis also features hydraulic shock absorbers, mitigating jolts on uneven terrain, reducing material spillage, and protecting core components from vibration damage.
Convenient Transport and Efficient Installation: Reducing Global Project Deployment Challenges
Addressing the pain points of global clients, such as “complex cross-border equipment transport and long on-site installation cycles,” the ZOOMRY Spiral Scraper Conveyor adopts a “modular disassembly + high pre-assembly ratio” design, ensuring equipment performance while significantly reducing transport and installation challenges, enabling rapid project commissioning.
The modular transport design disassembles the equipment into four standard units: spiral scraper module, conveyor belt module, chassis module, and control module, each sized to fit a 40-foot high-cube container (12.03 m long × 2.35 m wide × 2.69 m high). The spiral module folds hydraulically to a height below 2.5 m and weighs under 18 tons; the conveyor belt module splits into 2-3 segments, each no longer than 6 m and weighing no more than 10 tons; the chassis and control modules are integrated into waterproof enclosures, requiring no special transport permits. Compared to traditional integrated scraper conveyors, this design significantly reduces cross-border logistics costs, and core components are factory-packaged with anti-rust and waterproof materials to prevent damage from jolts or moisture during transport, accommodating global logistics conditions.
The high pre-assembly ratio ensures rapid on-site commissioning: the equipment is 85% pre-assembled at the factory, including precise spiral-to-motor connections, conveyor belt installation and tuning, initial hydraulic pipeline connections, and control system parameter calibration. It undergoes 80 hours of full-load testing, simulating various capacity scenarios to ensure fault-free on-site installation. On-site installation requires only three core steps: first, modular unit assembly, connecting the spiral module to the chassis and the conveyor belt module to the frame with high-strength bolts, completed by two people in 2 hours; second, final connection of hydraulic pipelines and electrical plugs using quick leak-free connectors, taking no more than 1 hour; third, no-load testing and parameter fine-tuning, checking spiral rotation, chassis travel, and remote control functions, completed by a skilled team in one day for full commissioning. ZOOMRY provides a technical manual with step-by-step operation guides, highlighting special considerations for heavy equipment installation, such as bolt tightening torque and hydraulic system venting procedures, along with 24-hour online technical support via video guidance to assist clients in resolving installation issues, enabling deployment without a professional installation team.
