Pneumatic feeding system

for powders

Overview
PVC mixer feeding systems deliver powdered and granular raw materials and additives into industrial mixers with controlled flow rates and minimal contamination. These systems combine storage, conveying, dosing and automation to ensure reproducible mixtures for PVC production.

The Importance of PVC Mixer Feeding

• Product quality: Accurate dosing and steady feeding maintain consistent compound composition across production batches.
• Efficiency: Automated feeding reduces manual interventions and increases throughput.
• Operational costs: Precise material handling reduces waste, rework and material losses.
• Safety and hygiene: Closed conveying and dosing systems limit dust emissions and spillage, improving workplace safety and compliance.

Products and Services (related to mixer feeding)

• Silos and storage solutions — engineered storage for PVC resin, calcite, TiO2 and other powdered additives.
• Pneumatic conveying systems — closed, dust-free transfer of powders and granules to mixers.
• Dosing and feeding units — volumetric and gravimetric feeders for precise ingredient metering.
• Process automation and control — PLC/SCADA integration for recipe management, monitoring and traceability.

Sectoral Applications

• PVC profiles and window systems — uniform mixtures for extrusion quality and surface finish.
• PVC pipes and fittings — high-throughput feeding for continuous production lines.
• PVC cables — controlled dosing of flame retardants and specialty additives.
• PVC sheets and floor coverings — homogeneous blends to ensure mechanical and aesthetic properties.

Related Sectors / Use Cases

• Food powders (analogous conveying and dosing technologies where dust control is critical).
• Cable manufacturing (shared requirements for precision dosing and dust containment).
• General bulk-material industries requiring silos, feeders, pneumatic transport and automation.
