Precision Screw Feeders: Essential Auxiliary Equipment for Packaging Lines

Operational Excellence Through Continuous Supply
LOCUS GROUP screw feeders ensure uninterrupted material flow to filling machines by maintaining optimal hopper levels (10-65% capacity). Eliminate manual refilling and increase line productivity by 35%.

Engineered for Reliable Material Transfer
LOCUS FILLING’ screw feeders deliver accurate volumetric dosing (±0.3%) of free-flowing to cohesive materials:

  • Powders (0.01-1mm particle size)

  • Granules (1-10mm)

  • Pellets (5-20mm)

  • Fragile products (e.g., instant noodles)
