What is a Vacuum Loader for Granules?
A Vacuum Loader for Granules is a pneumatic material handling device used to automatically convey plastic granules or powder from storage bins or bags to processing machines like injection molding machines, extruders, or hoppers. It operates on a vacuum principle, drawing material via suction and delivering it efficiently without manual intervention.
It is an essential part of automated plastic processing and handling systems.
Manufacturing a vacuum loader involves mechanical design, precision engineering, and electronics integration:
Vacuum Motor / Blower: Creates suction to draw material.
Receiver Unit (Hopper Loader): Collects granules at the discharge end.
Filter System: Captures dust or fine particles before releasing air.
Suction Probe or Wand: Inserted into granule storage bag or bin.
Flexible Hose / Tubing: Connects source to receiver.
Controller / Timer: Automates loading cycle.
The body is usually made of stainless steel or aluminum for hygiene and durability.
Parts are cut, shaped, and assembled using CNC machining, welding, and powder coating (optional).
Incorporates a PLC-based or relay-based controller, timers, and sensors for level detection and automation.
Can include display interfaces and alarm systems.
Units are assembled and tested under simulated operating conditions to check suction power, filtration, and operational logic.
Vacuum loaders are used extensively in:
Plastic Processing Plants (injection molding, extrusion, blow molding)
Pharmaceutical Industry (for non-hazardous granules)
Food Industry (with hygiene-certified models)
Chemical Industry
Recycling Units
Masterbatch and Compounding Plants
Compact and Portable Design
Stainless Steel Hopper Construction
Replaceable Filters
Efficient Suction Blower
Overload and Level Sensors
Anti-Static and Dust-Free Design
Essential for maintaining material feed continuity in plastic processing.
Prevents machine downtime due to manual filling.
Ensures clean, dust-free handling of granules.
Labor Savings: Eliminates need for manual loading
Hygienic Handling: Reduces contamination and exposure
Consistent Feed Rate: Improves process efficiency
Compact Footprint: Fits into small spaces near machines
Low Maintenance: Minimal moving parts
