Core Functions of the Spiral Scraper Conveyor
As a versatile equipment addressing multiple needs such as spiral scraper conveyors, sand scrapers, grain scrapers, and sand and gravel scrapers, the core competitiveness of the ZOOMRY Spiral Scraper Conveyor lies in its "wide throughput adaptability + multi-material compatibility + flexible operation." Targeting the challenges of diverse material types, varying scales, and changing operating environments, it resolves issues of traditional scraping equipment such as "fixed throughput, poor material adaptability, and cumbersome operation" through structural optimization and functional integration, while meeting customers' dual demands for "equipment versatility and reliability."
Spiral Scraping Structure
The core spiral scraping system adopts a "wear-resistant blade + alloy tooth" design, with blade thickness reaching 6-8 mm and high-strength alloy teeth embedded on the outer side, offering 120% higher wear resistance than standard carbon steel blades. This design withstands long-term impact and abrasion from hard materials like sand, gravel, and ores. The spiral outer diameter ranges from 500-800 mm, paired with a scraping width of 2-3.2 m and a material retrieval width of 2.4-3.6 m, allowing flexible adjustment of scraping efficiency based on material pile density and operation scale: for lightweight materials like grains, the 800 mm large spiral diameter achieves a high throughput of 2000 tph; for medium-to-heavy materials like coal, the 500 mm spiral with alloy teeth precisely controls scraping speed to avoid overloading; for blocky materials like sand and gravel, the alloy teeth effectively break material clumps, ensuring continuous scraping without blockages.
The spiral system is equipped with an "adaptive pressure adjustment" function. When encountering oversized materials (e.g., sand and gravel with a diameter >300 mm), the spiral automatically adjusts its rotation speed and scraping depth to prevent blade damage from hard impacts. Additionally, sensors provide real-time feedback on material resistance, displayed on the HMI screen, assisting operators in optimizing operational parameters and reducing equipment failure risks.
Dual-Type Crawler Chassis
The chassis offers two optional configurations—rubber or steel crawlers—to precisely match different site conditions:
- Rubber crawler model 4009068, with an effective length of 2.9 m, uses high-elasticity, wear-resistant rubber material with a ground pressure of only 0.07 MPa, suitable for soft ground (e.g., mine tailings or grain piles), preventing equipment sinking while minimizing ground damage and protecting site infrastructure.
- Steel crawler model 40013554, with an effective length of 3.6 m, features carburized and quenched crawler plates (hardness HRC58-62), with 80% improved wear resistance, ideal for hard, rough surfaces (e.g., sand and 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 with planetary reducers, delivering an output torque of 3500 N·m, enabling smooth steering and movement even under full load. The standard chassis outer width is 2.3 m, with optional widening customization to enhance stability on complex terrains.
Dual-Mode Electrical Control System
The equipment’s electrical control system features a "stainless steel rainproof control cabinet + wireless remote control handle" dual-control mode, fully adaptable to dusty and rainy outdoor environments. The control cabinet shell is made of 304 stainless steel with an IP65 protection rating, resisting water and dust ingress, and internal components are sourced from internationally renowned brands to ensure long-term stable operation. The wireless remote control handle has an effective range of 100 meters, supporting one-touch start/stop, spiral speed adjustment, chassis movement, and conveyor belt start/stop, allowing operators to monitor and adjust operations from a safe distance, significantly enhancing operational safety and convenience.
Additionally, the control system includes an "operation memory" function, capable of storing three sets of commonly used operational parameters (e.g., spiral speed, conveyor belt speed), enabling one-touch recall when switching material types, reducing setup time and improving operational efficiency.
Core Components
The long-term stable operation of the ZOOMRY Spiral Scraper Conveyor relies on targeted designs for "wear resistance, adaptability, and ease of maintenance." From the spiral system to the conveyor system, each component undergoes multi-condition simulation testing at ZOOMRY’s quality testing center, ensuring compatibility with various bulk materials and environments for long-term operational needs.
Spiral Scraping System
The spiral system’s drive unit uses a 22-75 kW high-power motor, flexibly matched to throughput needs: 100-500 tph low-throughput operations use 22-37 kW motors, 500-1200 tph medium-throughput use 45-55 kW motors, and 1200-2000 tph high-throughput use 75 kW motors, with motor efficiency above 95.5%, saving 10% energy compared to standard motors and featuring an IP55 protection rating to withstand outdoor dust and moisture. The accompanying gearboxes offer three models—ZQ350 dual output, ZQ400 dual output, and ZLY250 hardened gear dual output—with transmission efficiency above 97%. The hardened gear gearboxes provide 50% higher load-bearing capacity than standard models, handling instantaneous impact loads during spiral scraping and extending drive system lifespan.
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 under 2 hours. The teeth are bolt-fixed, requiring simple tools for replacement, enabling customers to perform maintenance without professional engineers.
Conveyor Belt System
The conveyor belt system covers a width range of 800-1600 mm, allowing flexible selection based on throughput and material size: 800-1000 mm width suits 100-800 tph low-to-medium throughput operations, while 1200-1600 mm width suits 800-2000 tph high-throughput operations. The conveyor belt material is a nylon core anti-slip rubber belt with a longitudinal tensile strength of 1600 N/mm and an 8 mm deep diamond-patterned anti-slip surface, improving slip resistance by 40% to prevent material sliding during transport, especially suitable for wet coal or sticky sand and gravel.
The conveyor belt is driven by a 15-30 kW electric drum, eliminating the need for additional motors and gearboxes, offering a compact structure and easy maintenance. The electric drum has an IP54 protection rating with a built-in overheat protection device, automatically stopping at temperatures above 120℃ to prevent burnout. The conveyor belt discharge height is fixed at 4 meters, matching the feed height of common trucks and conveyors, ensuring rapid material transfer with minimal spillage loss.
Hydraulic and Chassis System
The hydraulic system’s core is an 11-18.5 kW hydraulic pump station, flexibly matched to chassis type and spiral specifications: rubber crawler chassis pairs with an 11 kW pump station, while steel crawler chassis and large spiral specifications pair with 15-18.5 kW pump stations. The pump station has a 200 L oil tank capacity with dual filtration (10 μm precision), achieving NAS 8 hydraulic oil cleanliness, reducing hydraulic component wear and maintaining an annual failure rate below 0.5%. Hydraulic pipelines use high-pressure hoses (30 MPa working pressure) with stainless steel fittings, offering excellent corrosion resistance suitable for dusty and salt-fog environments.
The chassis movement system integrates with hydraulic motors, supporting stepless speed adjustment from 0-3 km/h, allowing flexible movement pacing based on operational needs. The chassis includes hydraulic shock absorbers to mitigate impacts from uneven terrain on the spiral and conveyor belt, reducing material spillage and protecting core components from vibration damage.
Electrical Control System
In addition to the dual-control mode, the electrical control system features multiple safety protections: in emergencies, both the remote control handle and the control cabinet have emergency stop buttons, cutting off all power instantly to ensure operational safety. The spiral and conveyor belt are equipped with overload protection, automatically stopping and alarming when the load exceeds 110% of the rated value to prevent motor burnout. The control cabinet includes temperature and humidity sensors, triggering audible and visual alarms when environmental conditions exceed normal ranges (temperature -20℃ to 60℃, humidity <90%), prompting operators to take protective measures.
The control system supports multi-language switching (English, Russian, Spanish, etc.) with a clear, intuitive interface displaying key parameters (e.g., spiral speed, conveyor belt speed, operating duration) in real-time for easy monitoring. The system can store 100 historical fault records, exportable via USB, facilitating fault tracing and maintenance optimization.
