ZR80D Hopper Feeder

The ZR80D Hopper Feeder is a core piece of equipment developed by ZOOMRY specifically for multi-material feeding scenarios. As a primary 300 TPH (Tonnes Per Hour) feeder, it is equipped with a large-capacity 8 m³ hopper and achieves stable feeding at a belt speed of 2.0 m/s. It features an adjustable belt tensioning system, enabling flexible adaptation to materials with different properties such as sand, gravel, and coal. Its wheel-type chassis design results in a minimum turning radius of only 6 meters, ensuring operational flexibility. The diesel-powered model controls fuel consumption to ≤20 L/h, balancing high efficiency and energy conservation. Additionally, it has obtained international certifications including CE and EAC, making it the preferred foldable hopper feeder for scenarios such as aggregate plants and small ports, thanks to its "multi-adaptability, high flexibility, and low energy consumption" characteristics.

Core Functions of the ZR80D Hopper Feeder

As a professional feeding equipment for aggregate plants, the core competitiveness of the ZR80D Hopper Feeder lies in "adaptability for multi-material compatibility + mobility for flexible operation". Addressing pain points such as differences in material properties and operational space constraints, it realizes "one equipment for multiple materials, flexible operation in small spaces" through functional optimization. This not only solves the problems of "poor material adaptability and inconvenient relocation" of traditional feeders but also meets the dual demands of "efficiency and energy conservation" in multi-material operation scenarios.

Adjustable Belt Tensioning System

The equipment is equipped with a dual-mode (manual + hydraulic) adjustable belt tensioning system, allowing precise adjustment of belt tension according to material properties:

• When conveying materials with coarse particles and high friction coefficients (e.g., sand and gravel), the tension can be adjusted to a high level (tension value: 8-10 kN) to prevent uneven feeding caused by belt slippage.
• When conveying soft and sticky materials (e.g., coal), the tension can be appropriately reduced (tension value: 5-7 kN) to minimize material crushing due to belt extrusion and reduce belt wear.

No component disassembly is required for adjusting the tensioning system; adjustments can be completed using the adjustment knobs and hydraulic control valves on the side of the equipment, taking ≤15 minutes and requiring no professional engineers. Furthermore, the belt tensioning mechanism is equipped with a tension monitoring device that provides real-time tension feedback and displays the value on the HMI (Human-Machine Interface) screen, avoiding belt damage caused by excessive manual adjustment and extending the belt service life.

Wheel-Type Chassis

The chassis is made of high-strength, lightweight alloy steel, and its overall structure has been optimized through finite element analysis. This design ensures load-bearing performance while controlling the equipment's self-weight. Equipped with 4 sets of reinforced solid tires (each with a load capacity of 10 tons), the minimum turning radius is only 6 meters, significantly smaller than the 8-10 meter range of traditional feeders. This design allows the equipment to flexibly turn and maneuver in compact operational areas, enabling material transfer without frequent adjustments to the operation route.

The chassis is also equipped with a hydraulic shock absorption system. When operating on uneven ground, it can buffer the impact of jolts on the equipment, reduce the shaking and spilling of materials in the hopper, and at the same time protect core components (such as motors and hydraulic systems) from vibration damage, thereby enhancing the overall stability of the equipment.

Low-Energy Design of Diesel-Powered Model

The diesel-driven version is equipped with a National III standard diesel engine, specially calibrated by ZOOMRY. Its fuel consumption is controlled to ≤20 L/h, achieving over 15% energy savings compared to traditional diesel feeders of the same class. The engine adopts high-pressure common rail injection technology, ensuring more complete fuel combustion. This not only reduces fuel consumption but also lowers exhaust emissions, complying with the EU emission limit standards for non-road mobile machinery.

Additionally, the engine is equipped with an intelligent start-stop function: it automatically shuts down when the equipment is on standby for more than 10 minutes, avoiding idle energy waste. It can also automatically adjust the output power according to the feeding volume. For example, when the feeding volume drops below 150 TPH, the engine automatically switches to a low-power mode to further optimize energy consumption.

8 m³ Large-Capacity Hopper

The hopper adopts a trapezoidal structure with a "wide mouth and deep cavity", providing an effective volume of 8 m³. It can hold larger batches of materials, reducing the frequency of material replenishment by loading equipment such as loaders and excavators, and improving the overall operational continuity.

The inner side of the hopper is lined with 12 mm thick wear-resistant manganese steel plates, which increase wear resistance by 80% compared to ordinary carbon steel when handling wear-resistant materials such as sand, gravel, and ore. The bottom of the hopper is designed as an inclined discharge port (with an inclination angle of 15°), and combined with the built-in flow guide plate, it can guide materials to flow evenly onto the belt, avoiding feeding blockages caused by local material accumulation.

Furthermore, the hopper supports a hydraulic folding function. After folding, its height is reduced by 40%, significantly reducing transportation and storage space requirements, and adapting to cross-border transportation and compact site storage needs.

Core Components

Drive System

The drive system offers optional gear motors from internationally renowned brands, including SEW (Germany), FLENDER (Germany), and JlE (China). With an output power of 22 kW, it accurately matches the 300 TPH feeding requirement. The motor efficiency reaches over 95.5%, reducing ineffective energy consumption compared to ordinary motors.

The motor has an IP55 protection rating, and its housing undergoes anti-corrosion treatment, enabling it to resist dust and moisture erosion commonly encountered in aggregate plants and small ports. It is equipped with built-in overload protection and overheating protection devices: when the feeding volume exceeds 330 TPH or the motor temperature exceeds 120°C, it automatically shuts down and triggers an alarm, preventing motor burnout and reducing maintenance risks.

In addition, the motor and reducer are connected by a flexible coupling, which can buffer the impact load during startup, protect transmission components, and extend the overall service life of the drive system.

Belt Conveying System

The belt adopts a high-wear-resistant PVG flame-retardant conveyor belt (14 mm thick), with a diamond-shaped anti-slip pattern on its surface, increasing the anti-slip coefficient by 45%. It can stably convey wet and slippery coal as well as sticky sand and gravel, avoiding material slippage and spillage.

Both sides of the belt are equipped with 350 mm high rubber side skirts to further prevent material side leakage. The side skirts are made of aging-resistant rubber material, with a service life of over 2000 hours. Combined with the adjustable belt tensioning system, the belt tension can be adjusted according to material properties, not only ensuring conveying stability but also reducing belt deformation caused by excessive stretching. This extends the belt replacement cycle to more than 1.5 years, lowering maintenance costs.

Intelligent Control System

Considering the operating habits of global customers and multi-scenario operation needs, the control system of the ZR80D Hopper Feeder focuses on "intelligence and convenience". It is equipped with a 10-inch high-definition HMI touchscreen, supporting multi-language switching (including English, Russian, Spanish, etc.). The interface only retains core functions such as "Start/Stop, Feeding Speed Adjustment, Belt Tension Control, and Hopper Folding/Unfolding", with no complex parameter settings. Ordinary operators can operate it independently after 30 minutes of training.

The system supports two control modes:

• Local control mode: Completed through the operation panel on the equipment itself, suitable for short-distance operations.
• Remote control mode: Equipped with a wireless remote control with a range of 50 meters, allowing operators to observe material conditions and make real-time adjustments in a safe area, avoiding frequent travel between the equipment and the feeding point.

In emergency situations, emergency stop buttons are installed at both ends of the equipment; pressing them immediately cuts off all power, ensuring operational safety.

Hopper Structure

In addition to the 8 m³ large-capacity design, the hopper has undergone multiple durability optimizations:

• Reinforcing ribs are welded on the outer side of the hopper to enhance overall rigidity and prevent deformation caused by long-term material bearing.
• The edge of the hopper's feeding port is processed with a circular arc transition to reduce impact wear during material unloading by loading equipment.
• An optional vibration arch-breaking device is available. For easy-caking materials (e.g., wet sand, coal powder), it can prevent material bridging and blockage through high-frequency vibration, ensuring continuous feeding.

These designs not only extend the service life of the hopper but also reduce the frequency of manual cleaning and maintenance, adapting to long-term operation needs of multiple materials.

Rapid Project Implementation Support

To address the pain points of high global project transportation costs and long installation cycles, the ZR80D Hopper Feeder adopts a "foldable compression + high-proportion pre-assembly" design. While ensuring performance, it significantly reduces transportation and installation difficulties, ensuring rapid project commissioning.

Compliant Loading in 40ft High Cube Containers

The ZR80D Hopper Feeder supports hydraulic folding. After folding, the overall dimensions of the equipment are reduced to 13 m × 2.4 m × 2.6 m, fully complying with the transportation limits of 40ft high cube containers (length 12.03 m × width 2.35 m × height 2.69 m). No special permits for over-width or over-height transportation are required.

All core components (such as drive motors, hydraulic power packs, and control systems) are fixed and protected at the factory. Only the connecting pins between the hopper and the boom need to be removed for container loading, avoiding component displacement and damage during transportation. Compared with the traditional "bulk loading + welding fixation" transportation method for feeders, cross-border logistics costs are reduced by 25%, and structural risks associated with on-site reassembly are minimized, adapting to logistics and transportation needs in multiple global regions.

High Installation Efficiency

Before leaving the factory, the equipment has completed 90% of pre-assembly work. Key processes such as hydraulic pipeline connection, electrical wiring, and belt installation are debugged in place at the factory. On-site, only 3 core processes are required:

1. Unfold the folded hopper and fix the connecting pins, which can be completed by one person in 1.5 hours.
2. Connect the power supply or diesel generator set, and test the steering and oil pressure of the power system.
3. Conduct a no-load test run to check whether functions such as feeding and tensioning are normal.

The entire process can be completed in as fast as 4 hours, and a skilled team can put the equipment into operation within one day. ZOOMRY provides an installation guide manual, which marks the key points of each step and the models of required tools. Meanwhile, online technical support is available to assist in solving problems encountered during installation, eliminating the need for a professional installation team to complete deployment.
