Bulk Bag Unloader (Big Bag Discharger)

Bulk Bag Unloader (Big Bag Discharger) for Efficient and Dust-Tight FIBC Emptying

Key Features of the Bulk Bag Unloader

Clean, Dust-Tight Discharge

• Sealed docking station with clamp ring or inflatable seal ensures low-dust FIBC emptying.
• Integrated dust extraction port supports central collectors to maintain plant hygiene.
• Negative pressure design reduces airborne particles and cross-contamination.

Robust Lifting and Handling

• Heavy-duty frame with forklift pockets and optional electric hoist/gantry for 500–2000 kg big bags.
• Adjustable cross-beam and safety latch hooks for quick, secure bag changeovers.
• Spout tensioner and access door allow safe tying/untie operations without spillage.

Reliable Flow Aids for Difficult Powders

• Pneumatic bag massagers, vibration pads, or air pads to break bridges and rat-holing.
• Agitation hopper and flow cone for cohesive, hygroscopic, or compacted materials.
• Optional liner piercer and cutting knife for single-use lined bags.

Hygienic and Durable Construction

• Product-contact parts in SS304 or SS316L with food-grade gaskets and finishes on request.
• Smooth welds and radius corners minimize residue and simplify washdown.
• Wear-resistant coatings/liners for abrasive minerals extend service life.

Modular Integration and Safety

• Compatible with downstream screw feeder, pneumatic conveying, rotary valve, or belt conveyor.
• Inline magnet trap or sieve to protect downstream mixers/extruders from tramp metal or agglomerates.
• Interlocked doors, E-stops, and guards; CE compliance and ATEX options for combustible dust.

Application Areas

Construction and Building Materials

• Cement additives, dry mortar, gypsum, lime, calcium carbonate, silica flour.
• Stable discharge feeds mixers, silos, and batching systems with consistent throughput.

Furniture and Wood Panels

• Melamine/urea resin powders, fillers, flame retardants for MDF/HDF lines.
• Dust-controlled transfer improves workplace safety and board quality.

Automotive and Plastics

• PP/PE/PVC resins, talc, glass beads, masterbatch additives.
• Reliable unloading ensures uniform dosing to extruders and injection molding.

Chemicals and Detergents

• Soda ash, phosphates, zeolites, surfactant powders, catalysts.
• Corrosion-resistant build supports long-term performance with aggressive materials.

Food, Feed, and Nutraceuticals

• Sugar, starches, whey/milk powders, premixes, vitamins (with sanitary configuration).
• Hygienic design aligns with HACCP/GMP and quick changeovers between recipes.
