Small-Volume Radial Stacker with 500tph Capacity

Time:2025-10-03 20:16:44 Number of Clicks:

In bulk material handling scenarios such as mines, ports, and aggregate plants, "space constraints" and "high-capacity requirements" are often concurrent challenges. While traditional large-volume stackers can meet capacity demands, they struggle to fit into narrow spaces; on the other hand, small-scale equipment often slows down production due to insufficient capacity. ZOOMRY's small-volume radial stacker with a 500tph capacity not only achieves efficient conveying of 500 tons per hour but also overcomes space limitations through its modular and lightweight design.

Application Scenarios of the Small-Volume Radial Stacker

ZOOMRY's 500tph small-volume radial stacker core advantage lies in "accommodating high productivity in a small space". Its design fully considers the site characteristics of different industries worldwide, making it particularly suitable for the following three typical scenarios:

Medium and Small-Scale Mines & Mineral Processing Workshops

Underground mines or surface mineral processing workshops are often restricted by tunnel width and workshop layout, making it difficult for traditional stackers to be deployed flexibly. Thanks to its small-volume design, ZOOMRY's radial stacker can operate normally in workshops with a width of less than 10 meters. Its 500tph capacity perfectly matches the ore transfer needs of medium and small-scale mines—whether for metal ores such as iron ore and copper ore, or non-metallic ores such as limestone and kaolin, it can achieve continuous, uninterrupted stacking operations, avoiding production line congestion caused by excessive equipment footprint.

Port and Terminal Bulk Cargo Areas

Most old ports or inland river terminals worldwide face the problem of "tight shorelines and narrow storage yards". Adopting fixed stacking systems not only incurs high construction costs but also occupies valuable loading and unloading space. ZOOMRY's radial stacker supports radial rotation (maximum rotation angle of 110°, far exceeding the 70° limit of traditional belt conveyors), telescopic adjustment (customizable telescopic length), and luffing functions. It can flexibly adjust the stacking position within limited storage yard space. With a 500tph capacity, it can efficiently match the loading and unloading rhythm of small bulk carriers (e.g., Handysize-class ships with a deadweight of 10,000-35,000 tons) without requiring large-scale modifications to existing sites.

Building Materials and Chemical Plant Areas

In industries such as cement, aggregates, and chemical fertilizers, temporary stacking links are often needed between production lines and storage areas. Sites are usually fragmented by equipment and warehouses. The small-volume design of ZOOMRY's radial stacker allows it to move and operate in narrow areas such as gaps between production lines and beside warehouses. Its 500tph capacity can connect with the discharge speed of production lines (e.g., the 500tph crushing capacity of medium and small-scale aggregate plants). Meanwhile, its sealed design reduces dust emissions, complying with international environmental standards such as EU CE and South Korean KCS, and meeting strict environmental requirements for plant areas worldwide.


Core Performance Parameters of ZOOMRY's Radial Stacker

The "practicality" of a stacker is ultimately determined by its parameters. The parameter design of ZOOMRY's 500tph small-volume radial stacker always centers on the three goals of "efficiency, compactness, and reliability", and all parameters have passed ISO 9001 quality management system certification and third-party testing:

  • Capacity and Material Adaptation: Rated capacity of 500tph, adaptable to bulk materials with a density of 1.2-2.8t/m³ (e.g., coal, ore, aggregates, chemical fertilizers). By adjusting the conveyor belt speed (2.0-2.5m/s) and hopper size, it can meet the stacking needs of different materials, avoiding material segregation, crushing, or contamination.
  • Volume and Transportation Convenience: The entire machine adopts a modular design and can be disassembled into standard components that fit into 40”HQ containers. No special over-limit transportation permits are required during transportation, reducing transportation costs for overseas projects by 20%-30% compared to traditional stackers. On-site assembly only takes 10-20 days, and no complex civil engineering foundations are needed—only simple hardened ground is required for deployment.
  • Stacking Capacity and Flexibility: Maximum stacking height of up to 20 meters. Through radial rotation and telescopic functions, a single unit can cover a stacking range with a diameter of 30-50 meters. Its stacking capacity is 28% higher than that of fixed stackers of the same volume (for example, with kaolin and a 45° angle of repose, the stacking capacity with a 50-meter radius can reach over 100,000 tons). It supports three modes: manual, remote control, and PLC fully automatic. Operators can precisely adjust the stacking trajectory via the HMI touchscreen, reducing manual intervention.
  • Energy Consumption and Environmental Indicators: Equipped with internationally renowned brand gear motors such as SEW/FLENDER/JIE, combined with ZOOMRY's self-developed high-efficiency hydraulic power pack (500-650L oil tank), the energy consumption per unit capacity is only 0.08kW・h/t, 15% lower than the industry average. The conveyor belt adopts a dust-proof sealed design, with a dust concentration of less than 10mg/m³ and noise below 45dB (far better than China's GB standard of 55dB), complying with the ISO 14001 environmental management system and EU environmental requirements.


Features of the Radial Stacker

Modular and Lightweight Structure

The main frame of the equipment is made of high-grade Q355B carbon steel. The structural design is optimized through finite element analysis—while ensuring load-bearing strength (maximum load capacity of up to 120 tons), the overall weight of the machine is reduced by 15% compared to traditional stackers of the same capacity. The frame adopts a lattice structure, which not only reduces the footprint but also facilitates daily maintenance. Engineers can directly inspect internal components through the lattice gaps without disassembling the outer guard plates, improving maintenance efficiency by 40%.

Dual Safety Protection

In response to common risks during stacker operation such as "power failure and steel rope breakage", the equipment is equipped with dual safety guarantees:

  1. Power failure protection: The hydraulic winch automatically locks within 0.01 seconds after power failure, preventing the inner telescopic conveyor belt from suddenly falling.
  2. Steel rope breakage protection: Two mechanical limit devices are installed—even if the steel rope breaks, the inner conveyor belt can be caught by the limit devices, preventing equipment damage and material leakage. In addition, the equipment is also equipped with standard belt deviation switches and emergency pull-cord switches, complying with the safety standards of the Conveyor Equipment Manufacturers Association (CEMA).

Customized Adaptation

Considering the differences in site, materials, and standards among global customers, ZOOMRY provides end-to-end customization services:

  • For customers in cold regions of Russia, a -40℃ low-temperature start-up device and cold-resistant hydraulic oil can be added.
  • For customers in humid regions of Southeast Asia, motors and electrical components with IP67 protection rating are used.
  • For customers who need frequent movement, a crawler chassis (replacing the traditional wheeled chassis) can be selected to adapt to complex terrains such as muddy and rough ground. In addition, the equipment supports customization according to multiple standards such as CEMA, AS (Australian Standards), and GB (Chinese Standards), ensuring compliance in different countries and regions.


Full-Chain Quality Assurance

As a "reliable partner" in the global bulk material conveying equipment field, ZOOMRY has always adhered to the concept of "building high-quality conveying equipment and forging a century-old foundation". It provides full-chain quality assurance for radial stackers from R&D to production:

Multiple International Certifications

The equipment has obtained multiple international certifications: CE certification (for EU market access), EAC certification (for Russia and the Eurasian Economic Union market), KCS certification (for the South Korean market). It also complies with the requirements of the ISO 9001 quality management system and ISO 14001 environmental management system. It can directly enter the markets of major global economies without additional compliance testing, helping customers shorten the project implementation cycle.

Self-Developed Core Components

The core components of the stacker (idlers, pulleys, hydraulic system) are all independently produced by ZOOMRY, and their performance far exceeds industry standards:

  • Idlers: Made of HDPE or high-carbon steel, with radial runout ≤0.4mm (GB standard: 0.5mm) and axial displacement <0.4mm (GB standard: 0.7mm). Service life exceeds 50,000 hours, and noise is below 45dB.
  • Pulleys: For shaft diameters ≤190mm, 40Cr rolled material is used; for diameters ≥200mm, 40Cr forged material is used. The shell is processed by a CNC four-roll bending machine, with ovality <1.5mm. After welding, it undergoes ultrasonic flaw detection and stress relief treatment, ensuring its service life is synchronized with the main body of the equipment.
  • Hydraulic system: Adopts a top-tier domestic hydraulic power pack, equipped with a precision filter (filtration accuracy of 10μm), which can effectively prevent hydraulic oil contamination and reduce the failure rate. The mean time between failures (MTBF) exceeds 8,000 hours.

Strict Quality Inspection Process

ZOOMRY has an independent quality inspection center, including a chemical laboratory, hardness laboratory, idler laboratory, and mechanical performance testing laboratory, equipped with more than 60 professional testing equipments. Before leaving the factory, each stacker undergoes 12 static tests (e.g., component size and strength testing) and 8 dynamic tests (e.g., no-load operation and full-load stacking testing) to ensure that all performances meet standards. For overseas projects, adaptability tests are also conducted by simulating the environmental conditions of the target market (e.g., high temperature, low temperature, high humidity) to eliminate "incompatibility" issues.

In addition, the equipment also enjoys a 5-year main body warranty and a 2-year vulnerable parts warranty, far exceeding the industry average 3-year warranty standard.


Application Cases

Bulk Material Conveying in a Kaolin Mine

The width of the mine's mineral processing workshop was only 9 meters. Previously, a small fixed stacker with a capacity of only 300tph was used, which could not match the 500tph capacity of the new production line. After introducing ZOOMRY's small-volume radial stacker, it was quickly deployed through modular assembly. The stacker can achieve 100° radial rotation in the workshop, with a stacking height of 18 meters and a stacking capacity increased to 80,000 tons. It not only meets the capacity needs of the production line but also saves 20% of the site space, reducing annual production suspension losses caused by site congestion.

Bulk Material Conveying in an Inland River Port

An old terminal with a storage yard area of only 1,500㎡ needed to adapt to the loading and unloading needs of Handysize-class bulk carriers. ZOOMRY's small-volume radial stacker adopted a crawler chassis and a low-temperature start-up device (to adapt to the -15℃ winter environment in Europe). The equipment was disassembled and transported in 2 40”HQ containers, with on-site assembly taking only 15 days. After commissioning, the stacker can complete 500 tons of coal stacking per hour, covering the entire storage yard with its stacking range. The port's loading and unloading efficiency increased by 35%, and it complies with EU CE and environmental standards, with no compliance complaints.


Against the backdrop of the global bulk material handling industry transitioning towards "higher efficiency, greater compactness, and greener operations", ZOOMRY's 500tph small-volume radial stacker, with its core advantage of "accommodating high productivity in a small space", has become a key equipment for mines, ports, building materials, and other industries to resolve the "contradiction between space and capacity". From self-developed core components to global certifications, from customized solutions to full-cycle services, ZOOMRY has always focused on "customer value", helping global customers reduce production costs, improve production efficiency, and minimize environmental impact.
