ZOOMRY Heavy Duty Hopper Feeder is a core equipment developed for high-load bulk material handling scenarios in global mining and port operations. It seamlessly connects front-end large-capacity feeding equipment (large wheel loaders, heavy grab cranes) with back-end high-capacity processing equipment such as heavy-duty belt conveyors, telescopic stackers, mobile ship loaders, and truck unloaders, providing an integrated solution featuring super-large handling capacity + ultra-strong wear resistance + continuous stable operation.

With "heavy-duty design" as its core concept, the equipment balances high-capacity output and long-term durability: the hopper capacity ranges from 12–24 m³ in the horizontal stacking state, with a maximum handling capacity of up to 3,000 tons per hour (TPH). It is equipped with a 15–24 m high-strength tilting arm, capable of stably handling heavy bulk materials such as iron ore, granite, and coal with a particle size of ≤250 mm. The feeding system offers two options—heavy-duty belt and hardened steel chain plate—adapted to medium-wear and ultra-high-wear materials respectively. Meanwhile, it supports dual chassis configurations (wheeled and tracked), suitable for hard gravel ground in mining areas and open spaces in ports.

What Are the Heavy Duty Hopper Feeder Applications in Mining and Ports?

With the characteristics of "super-large handling capacity, ultra-strong wear resistance, and high stability", ZOOMRY Heavy Duty Hopper Feeder has served customers in large mines, deep-water ports, and heavy industry plants in more than 40 countries and regions around the world, playing a core role in various high-load scenarios.

Large Mining Areas

Mine raw material pretreatment requires rapid transportation of crushed heavy bulk materials to beneficiation or outward transportation systems. The 3,000 TPH handling capacity of ZOOMRY Heavy Duty Hopper Feeder can be directly connected to the mine crushing station. The 12–24 m³ hopper capacity can temporarily store full-hopper discharge from large grab cranes. Through the heavy-duty chain plate feeding system, materials are stably transported to underground or ground heavy-duty belt conveyors, realizing seamless connection of "crushing - feeding - conveying". This reduces the loader transfer link and significantly improves the daily average raw material handling efficiency of the mine.

Heavy Bulk Material Loading/Unloading at Deep-Water Ports

Large bulk carriers need to complete unloading and loading quickly to avoid port detention. The Heavy Duty Hopper Feeder can be installed at the front edge of the terminal. The 24 m long tilting arm is directly connected to the mobile ship loader, and the 3,000 TPH handling capacity can match the unloading rate of large grab unloaders. The heavy-duty belt feeding system can reduce the scattering of coal and iron ore. The wheeled chassis supports rapid movement within the port, and a single piece of equipment can meet the loading/unloading needs of multiple berths, improving the port's bulk material handling efficiency and shortening the ship's berthing time.

Raw Material Transfer in Heavy Industry Plants

Materials such as coke and cement clinker have the characteristics of high wear and the need for continuous conveying. ZOOMRY Heavy Duty Hopper Feeder adopts a 10 mm hardened steel hopper lining and chain plate feeding system, which can withstand continuous impact of heavy bulk materials. The 24 m³ hopper capacity reduces the number of round trips of feeding equipment. The dual-motor drive system supports 24-hour continuous operation, meeting the "non-stop production" raw material supply needs of the plant.

How to Choose Between Belt Feeder and Chain Plate Feeder for High-Load Applications?

The performance design of ZOOMRY Heavy Duty Hopper Feeder is fully centered on "continuous operation under high load". From the feeding system to the structural framework, drive and protection, all adopt heavy-duty standards to ensure low-failure operation of the equipment under harsh working conditions.

Dual-Mode Feeding System: Belt vs Chain Plate

• Heavy-duty belt feeding: Adopts a 1,400 mm wide EP 800 type 5-layer structure, with an 8 mm base belt and a 2 mm wear-resistant layer, featuring a tensile strength of 800 N/mm. Impact-resistant and tear-resistant, suitable for medium-wear materials such as coal and cement clinker. The service life of the belt is more than 50% longer than that of ordinary heavy-duty equipment.
• Hardened steel chain plate feeding: Uses 8 mm thick hardened steel material with professional wear-resistant surface treatment, which can withstand direct impact of large-particle-size materials and avoid the risk of belt scratches. The chain plate connections are fixed with high-strength bolts to reduce loosening failures.

The system is equipped with a high-power variable frequency drive (VSD), which can realize stepless speed regulation of 0–3,000 TPH. The feeding rate can be dynamically adjusted according to the handling capacity of back-end mobile ship loaders and telescopic stackers, avoiding overload blockage or capacity waste caused by insufficient speed.

Heavy-Duty Structural Framework for 3000 TPH Capacity

• Hopper: Welded from 16 mm thick Q355B steel plates, the inner wall can be optionally equipped with 15 mm ULF wear-resistant material or 10 mm hardened steel lining. The bottom has a U-shaped streamlined design to avoid accumulation and blockage of heavy bulk materials in corners, while reducing impact wear. The top of the hopper is equipped with a foldable "extendable capacity plate", which can expand the capacity according to feeding needs—capacity in the stacked state is 25% higher than in horizontal stacking.
• Tilting arm: Adopts a lattice-type or folded plate-type heavy-duty framework (selected based on handling capacity). The main load-bearing beam is an H-beam with anti-corrosion surface treatment, suitable for long-distance conveying of 15–24 m and capable of withstanding continuous pressure and impact of heavy bulk materials. The two sides of the tilting arm belt/chain plate are equipped with 150 mm high wear-resistant skirt plates to effectively prevent material scattering.
• Chassis: Supports dual options (wheeled and tracked). The wheeled chassis uses large engineering tires, suitable for rapid movement in open port spaces. The tracked chassis is a steel heavy-duty track with a ground contact pressure as low as 0.1 MPa, suitable for gravel ground in mining areas. It is also equipped with hydraulically adjustable jack outriggers, which can quickly fix the equipment after positioning to reduce vibration during high-load operations.

Stable Drive and IP65 Protection for Continuous Operation

• Drive system: Adopts dual-motor direct drive, with power selectable according to needs. Combined with a planetary gear reducer, it ensures stable power output and can handle instantaneous high loads caused by concentrated feeding of large-particle-size materials. The hydraulic system is equipped with an independent oil cooler to avoid performance degradation caused by excessive oil temperature during high-load operations.
• Protection: The electrical control part has an IP65 (NEMA-4 class) protection rating, including a timer, emergency stop button, and cold start protection function, adapting to harsh environments such as high dust in mining areas and high humidity in ports. The feeding system and tilting arm are both equipped with fully enclosed protective covers to prevent splashing of heavy bulk materials and rainwater intrusion, extending the service life of components.
