Low Feed Hopper Feeder

ZOOMRY Low Feed Hopper Feeder is a specialized feeding equipment developed to address pain points in global bulk material handling, such as "limited lifting capacity of feeding equipment, low-ceilinged spaces, and easy material scattering". It can seamlessly connect front-end small and medium-sized feeding equipment (wheel loaders, small excavators, grab cranes) with back-end processing equipment (belt conveyors, telescopic stackers, truck unloaders, mobile ship loaders), providing domestic and foreign customers with an integrated solution featuring "low-height adaptation + wide-range feeding + controllable conveying".

With "low feed height" as its core design highlight, the equipment combines efficient feeding and space adaptability: the hopper capacity ranges from 7-12 m³ (horizontal stacking), the maximum handling capacity reaches 800 tons per hour (TPH), and it is equipped with a 20-28 m hydraulically adjustable tilting arm, capable of stably handling various bulk materials such as aggregates, ores, biomass (wood chips, straw), and coal with a particle size of ≤200 mm. Its unique feed inlet design and rear feeding structure adapt to low-height operating spaces and small/medium-sized feeding equipment, enabling feeding without additional lifting equipment. This completely solves the problems of "difficult feeding and large space occupation" of traditional high-hopper equipment, making it a core bulk material handling equipment for global low-feed scenarios (such as underground mines, low-ceilinged workshops, and small/medium-sized material yards).

Core Highlights of Low Feed Hopper Feeder

The design of ZOOMRY Low Feed Hopper Feeder fully focuses on "low-height adaptation, high feeding efficiency, and low material loss". Both its structure and system are optimized for low-feed scenarios to ensure efficient and stable operation in limited spaces:

Low Feed Height Design

The core low feed height design fundamentally solves the problem of insufficient lifting capacity of feeding equipment: the minimum height of the feed inlet can adapt to the discharge height of small and medium-sized wheel loaders (20-30 ton class), eliminating the need for additional material lifting equipment and reducing equipment investment and operation links. At the same time, it adapts to low-height operating spaces (such as underground mine roadways and workshops with limited ceiling height). The overall height of the equipment is more than 30% lower than that of traditional hopper feeders, allowing normal operation in environments with a clear height of 2.5 m, without the need for site reconstruction and reducing early-stage site construction costs.

Wide Inlet and Rear Feeding Structure

The hopper adopts a dual-optimized design of "wide feed inlet + rear feeding": the feed inlet width ranges from 3.5-4.2 m (adapted to hopper capacity), expanding the feeding coverage area. Small and medium-sized feeding equipment can discharge without precise alignment, reducing alignment time. The rear feeding structure adapts to site layout, allowing the equipment to be placed close to material piles or feeding points, shortening the movement distance of feeding equipment. At the same time, it avoids material scattering caused by "turning and discharging" during the feeding process, increasing the material utilization rate by more than 15%.

Controllable Feeding System

The equipment is equipped with a high-precision controllable feeding system to ensure uniform material output: the feeding belt is a 1200 mm wide EP 500 type 3-layer structure (5 mm base belt + 1.5 mm wear-resistant layer), which is tensile and wear-resistant, adapting to the conveying needs of different materials such as aggregates and biomass. It is equipped with a variable frequency drive (VSD), enabling stepless speed regulation of 0-800 TPH. The feeding speed can be dynamically adjusted according to the handling capacity of back-end belt conveyors and telescopic stackers, avoiding material blockage caused by excessive feeding speed or capacity waste caused by insufficient feeding speed. Meanwhile, height-adjustable side skirts are installed on both sides of the belt to further reduce material scattering during conveying and lower on-site cleaning workload.

Technical Parameters

Applicable Scenarios

With the characteristics of "low-height adaptation, wide feeding range, and multi-material compatibility", ZOOMRY Low Feed Hopper Feeder has served customers in underground mines, small and medium-sized quarries, low-ceilinged workshops, and biomass yards in more than 50 countries and regions around the world. Its core applicable scenarios include:

Small and Medium-Sized Quarries

Most small and medium-sized quarries use 20-30 ton class wheel loaders and small excavators for feeding. Traditional high-hopper equipment requires additional elevators to complete feeding, increasing costs and operation links. The low feed height (1.2-1.5 m) of ZOOMRY Low Feed Hopper Feeder can be directly connected to such small and medium-sized equipment. Combined with the wide feed inlet design, loaders can discharge without precise alignment. The 20-28 m tilting arm can directly convey aggregates to belt conveyors or telescopic stackers, realizing seamless connection of "feeding - conveying - stacking", and the operation efficiency is more than 25% higher than that of traditional equipment.

Low-Height Operation Areas in Ports

Some low-height loading and unloading areas in ports (such as old terminals and indoor warehouses) have limited ceiling height, making it impossible to install traditional high-hopper equipment. ZOOMRY Low Feed Hopper Feeder has a low overall height, allowing normal operation in environments with a clear height of 2.5 m. The rear feeding structure can be placed close to the edge of the terminal. Combined with the 20-28 m tilting arm, it can directly convey materials such as coal and cement clinker to mobile ship loaders or truck unloaders, meeting loading and unloading needs without site reconstruction. Meanwhile, the wide bell-mouth design reduces material scattering and lowers port cleaning costs.

Biomass Yards

Biomass (wood chips, straw) yards mostly use small grab cranes or loaders for feeding. Biomass materials are loose and easy to scatter, and excessive compression should be avoided. The low feed height of ZOOMRY Low Feed Hopper Feeder reduces the impact of falling materials and avoids biomass crushing. A dedicated material agitator can be optionally installed (adapted to biomass characteristics) to prevent material agglomeration. The optional herringbone pattern belt improves the stability of biomass conveying and avoids slipping, ensuring uniform feeding at a handling capacity of 800 TPH, which meets the continuous feeding needs of biomass power plants and organic fertilizer plants.

Underground Mines

Underground mine roadways have limited ceiling height (usually 2.5-3 m), making it impossible for traditional feeding equipment to enter. The low-height design of ZOOMRY Low Feed Hopper Feeder allows direct installation in roadways, and the rear feeding structure adapts to the roadway layout. The 7-12 m³ hopper capacity can temporarily store ores (particle size ≤200 mm) crushed in mines, and the 20 m tilting arm conveys them to underground belt conveyors, reducing the number of round trips of loaders in roadways and lowering safety risks and fuel consumption.

Product Advantages of Low Feed Hopper Feeder

Multiple Customization Options

The equipment supports multi-dimensional customized configurations, which can be adjusted according to operating scenarios and material characteristics: for high-wear materials (such as ores), the hopper inner lining can be optionally 6 mm hardened steel or 15 mm ULF wear-resistant material to extend service life; for biomass materials, a dedicated agitator and herringbone belt can be added to prevent agglomeration and slipping; for dust-sensitive scenarios (such as food raw material yards), the tilting arm can be equipped with a canvas or galvanized dust cover to reduce dust pollution; at the same time, the feed height can be fine-tuned to adapt to different models of small and medium-sized feeding equipment.

Full-Chain Equipment Linkage

ZOOMRY has a complete bulk material handling equipment matrix including belt conveyors, telescopic stackers, and mobile ship loaders. During the design stage, the Low Feed Hopper Feeder has reserved linkage interfaces (mechanical adaptation structure + communication interlocking device) with the full range of products, eliminating the need for additional customized adapter components. If customers purchase multiple types of equipment at the same time, they can directly realize synchronous start and stop of "feeding - conveying - stacking/loading" after delivery. For example, when the Low Feed Hopper Feeder is linked with a belt conveyor, the feeding speed and conveying speed can be dynamically matched through preset parameters to avoid material accumulation.

High Cost-Effectiveness

Relying on a complete domestic supply chain system, ZOOMRY Low Feed Hopper Feeder has significant advantages in cost control, and its equipment price is more in line with the budget needs of global small and medium-sized customers. At the same time, the transportation plan is optimized: the equipment can be disassembled and loaded into 40-foot (12 m) high-cube containers, or transported by ro-ro shipping, reducing global transportation costs. In terms of technical support, through cooperation with local logistics providers in major markets in Asia, Europe, and the Americas, "spare parts delivery within 72 hours" can be realized; the 24-hour remote diagnosis team can quickly locate faults, and through remote guidance and collaboration with local engineers, equipment downtime can be controlled within 48 hours.

Convenient Operation and Maintenance

The equipment adopts a modular design: the power unit, feeding system, and tilting arm can be disassembled independently. Daily maintenance (such as belt replacement and motor maintenance) does not require overall disassembly, reducing maintenance man-hours. The control panel integrates multi-language interfaces including Chinese, English, Spanish, and Russian, adapting to the operating habits of operators in different regions. At the same time, a detailed maintenance manual is provided, allowing the customer team to independently complete basic maintenance such as belt tension adjustment, lubricating oil addition, and hopper cleaning, reducing dependence on external technical personnel. The long-term use cost is more than 30% lower than that of traditional equipment.
