Glove Box Dust-Free Bag Unloader — OEB-4/5 Contained Unpacking for Toxic Battery Powders
Negative-pressure glove chamber with bag-in / bag-out liners and secondary filtration, engineered for NCM/NCA precursors, lithium salts and ultrafine powders.
Product Overview
Where Operator Safety and Product Purity Meet
The moment a toxic powder bag is cut open, two risks appear at once: the operator breaths it, and the plant breaths it. The Bulk Pro glove-box unloader removes both — the bag enters a sealed, negatively pressurized chamber, is opened through glove ports, and empties into a closed downstream conveyor. The emptied bag never leaves the containment envelope: it is sealed inside a bag-out liner and exits as controlled waste.
Because the chamber is also dust-tight toward the room, your product stays where it belongs — in the process, not on the walls. It is the standard entry point for our ternary (NCM/NCA) lines and any material with a strict OEL.

Engineering Features
Details That Decide Containment Performance
Glove-Port Chamber
Sealed working chamber with ergonomic glove ports and viewing panel for safe bag cutting and emptying.
Secondary Filtration
HEPA-grade secondary filter on the extraction path keeps containment even if the primary filter loads.
Bag-In / Bag-Out
Continuous liner transfer means the contaminated bag never exits containment — sealed waste, zero open exposure.
Closed Discharge
Docks directly onto vacuum or dense-phase conveying — no intermediate open hopper, no dust escape.
MES-Logged Operation
Every station event — bag count, purge, filter check — is timestamped for your audit trail.
Integrated Compactor
Optional online bag compactor reduces contaminated waste volume up to 80% before bag-out.

Glove Box Unloader — FAQ
Before You Specify Containment Equipment
The station is engineered to OEB-4 and OEB-5 envelopes. With bag-in/bag-out liners, negative-pressure operation and integrated secondary filtration, operator exposure below 10 μg/m³ is achievable for many toxic battery powders — the binding figure is set by your compound's OEL and confirmed by leak testing at FAT.
Standard units accept 5–25 kg small bags inside the glove chamber; configurations with integrated FIBC frames handle 500–1,500 kg big bags. A combined version with our patented unloading mechanism covers mixed packaging on one footprint.
Product-contact parts are fully accessible, with wipe-down or wash-in-place options depending on the wetted materials. Purge cycles and magnetic-trap checkpoints are documented in the MES layer so each material change is auditable.
