What is a Hopper Feeder Conveyor?

A hopper feeder conveyor, also known as a Grasshopper Conveyor, Portable Stacker, or Jump Conveyor, is a bulk material handling equipment integrating "material receiving, quantitative conveying, and flexible movement". Its core function is to uniformly convey bulk materials (such as ores, coal, cement, aggregates, etc.) received by the hopper to subsequent conveying equipment (such as belt conveyors, mobile ship loaders, etc.) at a preset speed or flow rate. At the same time, it can flexibly adjust its position according to operational needs to avoid material accumulation and blockage, ensuring the continuous operation of the production line.

Structure of the Hopper Feeder Conveyor

In terms of structural design, ZOOMRY's hopper feeder conveyor mainly consists of five core components, which work together to meet the needs of different industries worldwide:

• Receiving Hopper: Adopts an ultra-low design and is made of high-strength carbon steel or wear-resistant alloy. The inner wall's wear-resistant layer can be customized according to material properties (such as hardness, corrosiveness). Meanwhile, it offers customized designs with widths ranging from 3.5m to 5.7m to ensure smooth material unloading and avoid spillage and loss during the unloading process. It is suitable for the unloading needs of different types of trucks, wheel loaders, or excavators.
• Conveying Mechanism: Takes belt conveying as the core, equipped with a high-wear-resistant conveyor belt and a precise tensioning system. The conveying length can be customized from 15m to 30m according to needs, and it supports cascading of multiple devices to meet the material transfer requirements of short distances and multiple locations.
• Drive System: Provides two options: wheel-type and tracked. The wheel-type chassis adopts a reinforced solid structure, suitable for most flat sites; the tracked chassis can easily handle rough terrain, enabling all-terrain mobile operations without the need for complex foundation construction.
• Control System: Standardly equipped with PLC full-automatic control and an HMI touch screen, supporting remote control and manual switching. It can real-time monitor parameters such as conveying speed and material level height. At the same time, it has overload protection and emergency stop functions to ensure the safe operation of the equipment.
• Safety and Auxiliary Components: Include rubber skirts (to prevent material side leakage), grid screens (to filter large impurities), dust covers (to reduce dust pollution), and hydraulic jacks (for equipment positioning and leveling), fully complying with international safety standards.

Core Functions of the Hopper Feeder Conveyor

In bulk material handling scenarios, traditional fixed conveying equipment often faces problems such as "poor site adaptability", "low material transfer efficiency", and "high labor costs". The hopper feeder conveyor (grasshopper conveyor) accurately solves these pain points through targeted design, and its core functions can be summarized into the following five points:

• Multi-Terrain Adaptability: The wheel-type chassis is suitable for flat sites such as ports and factories, allowing quick transfer of operation points; the tracked chassis can stably travel on rough terrain such as mines and quarries without the need for pre-laid tracks or site leveling, significantly reducing initial investment.
• Efficient Collaboration: The ultra-low hopper can directly meet the unloading needs of loaders and excavators, avoiding material spillage during transfer; the conveying speed and flow rate can be precisely adjusted through the control system to ensure stable material supply for subsequent equipment (such as radial stackers and mobile ship loaders), preventing overload or insufficient supply.
• Small Space Occupation: The foldable boom design reduces the space occupied by the equipment by more than 40% when idle, especially suitable for operation environments with limited space; the customized conveying length of 15-30m can directly connect different production links, reducing the number of round-trip truck transfers and increasing overall operational efficiency by more than 30%.
• Multi-Scenario Adaptability: Whether it is ore transfer in sand and gravel quarries, raw material deployment in aggregate plants, or material handling in fly ash remediation projects, the equipment can adapt to the needs of different scenarios through power selection (diesel/electricity) and boom length adjustment, and can be put into use without additional modifications.
• High Quality and Long Service Life: Core components (such as idlers and rollers) adopt high-wear-resistant products independently developed by ZOOMRY. The idler noise is lower than 40-45dB (better than the Chinese GB standard of 55dB), and the rotational resistance is ≤2N (better than the GB standard of 3N), with a service life of more than 50,000 hours. At the same time, the optimized transmission system design reduces energy consumption by 15%-20% compared with traditional mobile conveying equipment, conforming to the global low-carbon production trend.

Collaboration between Hopper Feeder Conveyors and Other Bulk Material Conveying Equipment

The efficiency of bulk material handling depends on the "collaborative adaptability between equipment". As a professional manufacturer and EPC general contractor of bulk material conveying equipment, ZOOMRY has been deeply engaged in the industry for more than 20 years. It not only focuses on the R&D of bulk material conveying equipment such as hopper feeder conveyors but also pays attention to their functional complementarity with belt conveyors, mobile ship loaders, and truck unloaders, as well as the cascading application of multiple hopper feeder conveyors. Combining the standardization and customization capabilities of its full-series products, it creates "seamless connection, high efficiency and low consumption" scenario-based solutions for global customers.

Stable Feeding Collaboration with Belt Conveyors

ZOOMRY's belt conveyors cover various types such as long-distance ground conveyors, pipe belt conveyors, and large-inclination belt conveyors, which are widely used in large-scale bulk material transfer in industries such as mining, chemical engineering, and power plants. The collaboration between hopper feeder conveyors and belt conveyors mainly solves the pain point of "easy overload due to uneven feeding" of belt conveyors. After receiving materials unloaded by loaders and trucks through its own ultra-low receiving hopper, the hopper feeder conveyor controls the conveying volume error within ±5% by virtue of the PLC control system, and feeds materials to the belt conveyor at a constant flow rate. This prevents belt deviation and motor overload of the belt conveyor caused by a sudden increase in materials, or idling waste caused by material interruption.

For example, in mine long-distance bulk material conveying projects, ZOOMRY's hopper feeder conveyor can be directly deployed between crushing equipment and belt conveyors to uniformly convey crushed ores to belt conveyors. Cooperating with the large conveying capacity of belt conveyors (up to 2100m³/h), it forms a continuous process of "crushing - feeding - long-distance transfer". The entire system complies with ISO 9001 quality system and ISO 14001 environmental system certifications to ensure stable operation under harsh working conditions.

Efficient Ship Loading Collaboration with Mobile Ship Loaders

ZOOMRY's mobile ship loaders have the core advantages of "ultra-flexible movement and adaptability to multiple ship types". They can be designed for different tonnage ships such as barges, handy-sized ships, and Panamax ships, especially suitable for terminal operations with limited space. They realize precise ship loading through functions such as radial rotation and luffing. The collaboration between hopper feeder conveyors and mobile ship loaders focuses on solving the problem of "material stratification caused by fluctuating feeding during ship loading". Relying on its wear-resistant conveyor belt and precise drive system, the hopper feeder conveyor provides materials to the mobile ship loader at a constant flow rate (the handling capacity can match the needs of the ship loader, up to 3000m³/h), avoiding uneven draft of the ship caused by fluctuating material volume during ship loading, or stratification and compaction of materials in the cargo hold.

In port bulk cargo ship loading scenarios, the hopper feeder conveyor can be deployed at the front of the terminal. After receiving materials transferred by ship unloaders or trucks, it adjusts its position synchronously with the mobile ship loader (relying on the wheel-type/tracked chassis) to ensure the ship loader continuously obtains a stable material flow. Cooperating with the PLC automatic control program of the ship loader, it can increase the ship loading efficiency by more than 20%, adapting to the multi-ship type loading needs of global ports.

Unloading and Transfer Connection Collaboration with Truck Unloaders

ZOOMRY's truck unloaders cover two types: wheel-type (ZRLS-TU series) and tracked (ZRLD-TU series), with a handling capacity range of 200-1800tph. They are designed with 2-4 truck ramps, which can receive unloading from multiple trucks at the same time, and are widely used in scenarios such as quarries, ports, and power plants. The collaboration between hopper feeder conveyors and truck unloaders mainly solves the pain point of "material transfer congestion after unloading". After the truck unloader guides trucks to unload through hydraulic ramps, the hopper feeder conveyor receives materials through the ultra-low receiving hopper and quickly conveys the materials uniformly to subsequent equipment (such as belt conveyors and mobile ship loaders), avoiding material accumulation and blockage under the unloader, and forming a closed-loop process of "truck unloading - hopper temporary storage - uniform transfer".

For example, in the unloading scenario of aggregate plants, multiple raw material trucks unload simultaneously through the 4 ramps of the truck unloader. The hopper feeder conveyor receives the materials synchronously and conveys the aggregates to the aggregate silo or crushing equipment. Cooperating with the hydraulic support system of the truck unloader and the dust-proof design of the hopper feeder conveyor, it not only improves the unloading efficiency (capable of handling 1800t of materials per hour) but also meets environmental protection requirements, avoiding dust overflow.

Cascading Expansion Application of Multiple Hopper Feeder Conveyors

ZOOMRY's hopper feeder conveyor (grasshopper conveyor) itself has the characteristics of "modular design and flexible length adjustment", supporting customized conveying lengths of 15-30m and a foldable boom structure. When multiple devices are used in cascading, they can break through the conveying distance limit of a single device and form a flexible conveying chain of "multi-point receiving and long-distance transfer", which is especially suitable for large-area operation scenarios such as quarries and mines.

The core advantages of cascading multiple hopper feeder conveyors are: ① Distance expansion: By connecting 2-3 devices in series, the conveying distance can be extended to 60-90m to meet the needs of long-distance cross-regional transfer. Each device can independently adjust the angle and speed to ensure smooth material transfer; ② Multi-point adaptation: Each device can correspond to one unloading point (such as multiple loaders unloading at the same time), and the materials are collected to the same terminal (such as belt conveyors, stacking areas) through cascading to avoid single-point congestion; ③ Scenario flexibility: The cascading devices can choose diesel or electric drive according to site needs. Even in remote areas without electricity, they can operate independently with self-contained generator sets. In addition, the equipment can be disassembled and packed into 40"HQ containers, facilitating global transportation and on-site rapid assembly (installation can be completed in 10-20 days).

For example, in large aggregate plants, 3 hopper feeder conveyors are deployed in cascading to receive aggregate unloading from different mining points respectively. Through cascading, the aggregates are transferred to the central crushing area. Cooperating with the tracked chassis of each device, the position can be adjusted at any time to adapt to the mining progress, significantly improving the efficiency of aggregate collection and transfer.

Global Application Scenarios of Hopper Feeder Conveyors

Mining Quarries and Aggregate Plants

The operation sites of sand and gravel quarries and aggregate plants are mostly open-air and rough, and materials need to be transferred between multiple mining points and crushing points. ZOOMRY's tracked hopper feeder conveyor (grasshopper conveyor) can be directly deployed on-site. It receives materials unloaded by excavators through the ultra-low hopper and then conveys the materials to crushing equipment or radial stackers. Its tracked chassis can withstand the gravel terrain in quarries, avoiding equipment getting stuck or damaged, and ensuring continuous material transfer.

Bulk Material Handling at Ports and Terminals

In bulk material transfer scenarios at ports and factories, the site is relatively flat but the operation position needs to be adjusted frequently. ZOOMRY's wheel-type hopper feeder conveyor (grasshopper conveyor) can be quickly transferred through solid tires to connect trucks, ship unloaders, and belt conveyors. Its foldable boom reduces space occupation when idle, which is especially suitable for the operation needs of "limited space and efficiency priority" at ports and terminals, helping to speed up cargo turnover.

Chemical and Building Materials Industries

Raw materials in the chemical industry (such as chemical fertilizers and soda ash) or aggregates in the building materials industry (such as cement and sand) have high requirements for "sealing performance" and "cleanliness" during the conveying process. ZOOMRY's hopper feeder conveyor can be equipped with a fully sealed hopper and dust cover design to prevent materials from getting damp or contaminated. At the same time, according to the corrosiveness of materials, it uses HDPE or stainless steel liners to ensure long-term stable operation of the equipment, complying with the strict standards of the chemical industry.

Power and Energy Industries

Thermal power plants and biomass energy plants need to continuously convey fuels (such as coal and biomass pellets) to boilers. Once the material supply is interrupted, it will directly affect the power generation efficiency. ZOOMRY's hopper feeder conveyor is equipped with a highly sensitive material level sensor, which can real-time monitor the material stock in the hopper and automatically send a material replenishment signal when the material is insufficient. At the same time, it has an overload protection function to avoid equipment jamming caused by fuel agglomeration, ensuring the 24-hour continuous operation of the power plant.

Key Considerations for Choosing a Hopper Feeder Conveyor

For global customers, choosing a suitable hopper feeder conveyor (grasshopper conveyor) needs to be combined with their own operation scenarios and long-term needs to avoid inefficiency or cost waste caused by insufficient equipment adaptability:

• Operational Terrain: For flat sites (such as ports and factories), prioritize the wheel-type chassis; for rough terrain (such as mines and quarries), choose the tracked chassis to ensure the mobile stability of the equipment;
• Material Characteristics: According to the material particle size (such as fine powder, large ore) and humidity (such as wet coal, dry sand), decide whether to configure a wear-resistant liner or dust cover to avoid equipment wear or material contamination;
• Conveying Needs: Clarify the conveying length (15-30m optional) and handling capacity. For small projects (such as fly ash remediation), choose short-arm models with 15-20m; for large quarries, long-arm models with 25-30m are needed to support cascading use;
• Power Conditions: Choose electric drive for sites with stable power supply; choose diesel drive (equipped with generator sets) for areas without electricity or remote areas;
• Manufacturer Strength: Prioritize manufacturers with industry experience (such as ZOOMRY's 20 years of focus on bulk material equipment), international certifications, and full-cycle service capabilities to avoid production interruption caused by equipment quality problems or lack of after-sales support.
