Spiral Scraper Conveyor for Loading

The ZOOMRY Spiral Scraper Conveyor for Loading is a high-efficiency equipment designed specifically for the integrated needs of "scraping-loading" of bulk materials, combining the wear-resistant efficiency of a spiral scraper conveyor with the convenient flexibility of loading functions. With a conveyor belt width of 800-1600 mm and a fixed discharge height of 4 meters as its core configuration, it achieves a wide throughput range of 100-2000 tph. Equipped with a tracked chassis (optional rubber or steel) and a 100-meter wireless remote control system, it adapts to various bulk material operations in stockyards, ports, and other scenarios, completing the seamless process from "stockpile to truck" without additional transfer equipment. Certified by CE, EAC, and other international standards, and supported by rigorous quality control, it stands as the preferred choice for sand and gravel scraping and bulk material transfer, offering "streamlined processes, enhanced efficiency, and high adaptability." It also serves as a complementary equipment for self-propelled mucking machines in similar scenarios.

Core Functions of the Spiral Scraper Conveyor for Loading

As a specialized equipment focused on the seamless "scraping-loading" process, the core competitiveness of ZOOMRY’s Spiral Scraper Conveyor for Loading lies in "process simplification + scenario adaptability + operational convenience." Addressing the inefficiencies of traditional bulk material handling, such as the need for secondary transfer after scraping and equipment mobility limitations due to site constraints, it resolves issues like "complex multi-equipment coordination, long operation cycles, and excessive manual intervention" through functional integration and structural optimization, while meeting global customers’ dual demands for "international compliance and equipment durability."

Seamless Connection from Stockpile to Truck

The equipment adopts a collaborative design of a "spiral scraping unit + conveyor belt loading unit," eliminating the need for additional conveyors or loaders to complete the full process. The spiral system, with a 500-800 mm outer diameter and 2-3.2 m scraping width, efficiently scrapes bulk materials (such as sand, gravel, and coal). The 6-8 mm thick blades, lined with high-strength alloy teeth, can break lightly caked materials and reduce wear. The scraped materials are directly transported to the loading end via an inclined conveyor belt (12-15 m long), with a 4-meter discharge height precisely matching the feed height of mainstream global freight trucks (truck bed height of 3.5-4.2 m), minimizing material spillage or secondary lifting.

The integrated design of the spiral scraper conveyor for loading increases operational efficiency by 40% compared to traditional setups of "scraper + loader + conveyor." For example, at a throughput of 1000 tph, the loading time for a single batch of sand and gravel can be reduced from 1.5 hours to 50 minutes, while cutting equipment investment and manual operations by 30%, fundamentally reducing losses in the bulk material handling process.

Tracked Chassis

The equipment is equipped with a standard tracked chassis (self-propelled design, aligned with the terrain adaptability of self-propelled mucking machines), offering two configurations to meet different scenarios:

• Rubber tracks: Model 4009068, with an effective length of 2.9 m and a ground pressure of only 0.07 MPa, suitable for soft terrains (such as wet stockyard grounds or port storage areas), preventing equipment from getting stuck while minimizing ground damage to protect site infrastructure. The minimum turning radius is 5 m, allowing flexible adjustment of loading positions even in narrow stockyards.
• Steel tracks: Model 40013554, with an effective length of 3.6 m, featuring carburized and quenched track plates (hardness HRC58-62) with 80% improved wear resistance, suitable for hard, rough terrains (such as sand and gravel stockyards in mines or port terminals), 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, ensuring smooth start-stop and steering even under full load. The standard chassis outer width is 2.3 m, with optional widening customization to further enhance stability on complex terrains, meeting operational needs across diverse global climates and site conditions.

Dual-Mode Electrical Control System

The electrical control system of the spiral scraper conveyor for loading adopts a dual-mode design of "stainless steel rainproof control cabinet + wireless remote control handle," balancing outdoor durability and operational convenience. The control cabinet, made of 304 stainless steel with an IP65 protection rating, resists water and dust ingress (suitable for outdoor environments in ports and stockyards), with internal components sourced from internationally renowned brands to ensure long-term stable operation. The wireless remote control handle has an effective range of 100 meters, supporting full-function operations such as spiral speed adjustment, chassis movement, conveyor belt start-stop, and emergency shutdown, allowing operators to monitor loading progress from the truck driver’s seat or a safe area, avoiding close contact with material dust and equipment operation, thus enhancing operational safety.

Additionally, the control system supports multi-language switching (English, Russian, Spanish, Chinese), with an operator interface focused on "scraping-loading coordination," allowing one-touch recall of three commonly used parameter sets (e.g., spiral speed and conveyor belt speed for sand and gravel loading). This eliminates repetitive setup when switching material types, significantly reducing the learning curve for operators in different global regions.

Core Components

The long-term reliable operation of ZOOMRY’s Spiral Scraper Conveyor for Loading relies on targeted designs centered around "wear resistance, coordination, and ease of maintenance." From spiral scraping to conveyor belt loading, each component undergoes multi-condition simulation testing and international standard verification to ensure compatibility with various bulk material types and operational intensities worldwide.

Spiral Scraping System

The spiral system is the starting point of "integrated operations," with its design directly determining scraping efficiency and durability. The blades, 6-8 mm thick and lined with high-strength alloy teeth (hardness HRC60), offer 120% higher wear resistance than standard carbon steel blades, capable of handling prolonged impacts from hard materials like sand, gravel, and ores. The spiral outer diameter ranges from 500-800 mm, paired with a 2.4-3.6 m material retrieval width, allowing flexible adjustment of scraping volume based on material pile density (e.g., 800 mm large spiral for lightweight materials like grains, 500 mm spiral for medium-heavy materials like coal).

The drive unit uses a 22-75 kW high-power motor, precisely matched to throughput needs (22-37 kW for 100-500 tph, 45-55 kW for 500-1200 tph, 75 kW for 1200-2000 tph), with motor efficiency above 95.5% and an IP55 protection rating to resist 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 models provide 50% higher load-bearing capacity than standard models, handling instantaneous impact loads during spiral scraping and preventing operational interruptions due to drive failures.

Conveyor Belt Loading System

The conveyor belt system is the core link in the "scraping-loading" process, designed for "leak-proof, anti-slip, and loading adaptability." The belt width ranges from 800-1600 mm (800-1000 mm for 100-800 tph, 1200-1600 mm for 800-2000 tph), made of nylon-core anti-slip rubber with a longitudinal tensile strength of 1600 N/mm. The surface features an 8 mm deep diamond-patterned anti-slip design, improving slip resistance by 40%, preventing wet coal or sticky sand and gravel from slipping during transport. The belt is equipped with 350 mm high wear-resistant rubber side skirts with embedded steel wire frames, reducing material leakage and meeting the needs of "continuous loading without loss."

The drive uses a 15-30 kW electric drum (no additional motors or gearboxes required), offering a compact structure and easy maintenance. The electric drum has an IP54 protection rating with built-in overheat protection (automatic shutdown above 120℃). The conveyor belt length of 12-15 m, paired with a fixed 4-meter discharge height, perfectly matches mainstream global freight trucks (bed height 3.5-4.2 m), enabling direct loading without secondary transfer, significantly shortening operational cycles—a key advantage distinguishing it from standard spiral scraper conveyors.

Hydraulic and Chassis System

The hydraulic system powers chassis movement and spiral adjustments, with a core 11-18.5 kW hydraulic pump station (11 kW for rubber tracks, 15-18.5 kW for steel tracks and large spirals). The pump station has a 200 L oil tank capacity with dual filtration (10 μm precision), achieving NAS 8 hydraulic oil cleanliness, reducing 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 for complex environments like high-salt port areas or dusty mines.

The chassis movement system integrates with hydraulic motors, supporting stepless speed adjustment (0-3 km/h), allowing flexible movement pacing based on loading rhythms. Hydraulic shock absorbers mitigate impacts from uneven terrain, preventing material spillage and protecting core components from vibration damage, ensuring "stable scraping and loading during movement" for flexible operations in multi-stockpile stockyards or multi-berth ports.

Modular Transportation and Efficient Installation
