Specialized FIBC/Big Bag Filling Systems for Bulk Powders & Granules
Precision Handling of High-Volume Materials.
Engineered for Heavy-Duty Bagging Operations.
LOCUS GROUP designs heavy-duty bagging systems for efficient filling of 500-2000kg FIBCs with:
Fine powders (≤50µm) to coarse granules (≤25mm)
Food, chemical, pharmaceutical, and mineral applications
Dust containment with ≤5mg/m³ emission
Food powders (flour, starch, protein blends)
Industrial minerals (cement, silica sand)
Chemicals (fertilizers, polymers)
Pharmaceutical intermediates
LOCUS FILLING designs and commissions purpose-built FIBC fillers exclusively for 500-2000kg bulk bags — distinct from our auger, multihead, or drum fillers.
