Bulk material handling has long been constrained by off-the-shelf equipment that cannot cope with difficult material properties or strict environmental standards. The dust-controlled hopper system was engineered to break through those barriers.
Rather than serving as a passive silo, it functions as an integrated processing platform - fusing advanced materials science, smart engineering design, and tight environmental controls into a single solution.
The system of the dust-controlled port hoppers is already in operation at Sun Metals' Townsville smelter, where it handles the demanding loading and unloading of zinc concentrate and zinc ferrite. The result is a fully enclosed, dust-free workflow that spans everything from initial receipt and storage through to rapid truck and ship loading - delivering efficiency and cleanliness at every stage.
Zero tolerance for environmental violations: Dust emissions from the transfer of fine particulate materials, such as zinc concentrate, must be eliminated to meet the strictest regional environmental regulations.
Extreme material characteristics of the dust-controlled hoppers: The material being processed is easily compacted zinc concentrate with extremely poor flowability. Conventional hoppers are prone to problems such as bridging and rat holes, leading to unloading interruptions.
Stringent efficiency requirements: Loading large road trains must be completed in an extremely short time, placing extreme demands on the system's throughput and reliability.
Our design philosophy starts with one rule: understand the material before you engineer the equipment. Early in the project, we worked with specialist consultants to run full flow-characterisation tests on every material stream. The results were clear - conventional designs simply would not work. We needed a clean-sheet solution.
Gravity-Flow Architecture - Built for Materials That Don't Want to Move
Oversized Discharge Outlet: Poor flowability is the enemy. We blew past conventional outlet dimensions to create a dramatically enlarged hopper exit, slashing the friction zone and wall pressure that cause arching. The result: even the most stubborn materials discharge reliably under gravity alone - no air cannons, no vibration, just clean, controlled flow.
Built Tough. Built a dual-purpose.
220-ton heavy-industrial frame: Designed for nonstop, high-frequency operation over the long haul - no compromise on structural integrity.
Bidirectional processing: This is the real differentiator. The same hopper receives and unloads zinc concentrate for in-plant smelting and efficiently loads zinc ferrite for export ships. One system, two workflows - maximizing asset utilisation and site flexibility.
Our unique batch rapid-loading process for the dust-controlled hopper: To efficiently transfer materials to road trains, we have developed an automated batch-loading procedure. This dust-controlled hopper system precisely controls the flow rate and unloading time for each batch of materials and works intelligently in conjunction with the movement of transport vehicles, ultimately achieving an industry-leading efficiency of "fully loading a 90-ton triple road train within 10 minutes".
Fully Enclosed Negative Pressure Environmental Control System
Fully Enclosed Loading Bay - Zero Dust Escape
Truck loading happens inside a sealed, environmentally controlled chamber, physically isolating every particle from the outside air.
Active Dust Capture & Filtration
A high-capacity extraction unit paired with a self-cleaning filter array maintains negative pressure throughout the loading cycle. Dust is pulled into the filtration system the instant it forms - delivering near-zero emissions at every loading and unloading point.
Dust Control Starts at the Source
An auxiliary suppression unit sits right at the inlet grating where material first enters the hopper. That means dust is tackled from the very first contact - giving you full-chain control from feed through to final loading.
ENJUE dust-controlled port hopper system demonstrates that, when faced with the most challenging industrial material handling problems, customized engineering design based on in-depth analysis can transform these challenges into a competitive advantage that is efficient, reliable, and environmentally friendly.
