Product Description
In modern plastics processing, efficient material handling is just as important as extrusion, mixing, and dosing accuracy. Manual feeding methods often lead to labor inefficiencies, material contamination, dust pollution, inconsistent feeding rates, and increased operating costs.
The Vacuum Conveyor Loader, also known as a Negative Pressure Vacuum Loader, is designed to automatically transport plastic powders, pellets, granules, and blended materials from storage points to mixers, batching systems, extruders, and processing equipment through a fully enclosed vacuum conveying system.
Manufactured by Zhangjiagang Chenxing Machinery Co., Ltd., this intelligent conveying solution significantly improves production automation, reduces labor costs, and creates a cleaner and safer manufacturing environment.
A Vacuum Conveyor Loader is a negative-pressure pneumatic conveying system that uses vacuum suction generated by a blower to transport materials through pipelines to designated destinations.
The system is widely used for:
Plastic powder conveying
Plastic pellet conveying
PVC resin feeding
Compound material transportation
Automatic batching systems
Extrusion production lines
Chemical powder handling
Centralized feeding systems
Unlike traditional manual feeding, vacuum conveying enables fully enclosed and dust-free transportation of materials throughout the production process.
Many factories still rely on manual feeding methods, which often result in:
High labor costs
Dust pollution
Material loss
Feeding inconsistencies
Production interruptions
Workplace safety concerns
As labor costs continue rising globally, manufacturers are increasingly adopting automated conveying solutions to improve efficiency and production consistency.
A Vacuum Conveyor Loader eliminates these challenges while supporting smart factory automation initiatives.
The system operates based on vacuum negative-pressure conveying technology.
A high-efficiency vacuum blower creates negative pressure inside the conveying pipeline.
Plastic powders, pellets, or blended materials are drawn from storage silos, bags, hoppers, or containers.
Materials travel through enclosed pipelines to the target equipment.
A multi-stage filtration system separates materials from conveying air.
Materials are automatically discharged into:
Mixers
Batching systems
Storage hoppers
Extruders
Processing machines
The entire process is automated and requires minimal operator intervention.
The system adopts a completely enclosed conveying structure.
Benefits include:
Cleaner workshops
Improved employee safety
Reduced material waste
Environmental compliance
This feature is particularly important when handling PVC powder, calcium carbonate, additives, and other fine materials.
According to application requirements, the system can achieve conveying capacities from:
Depending on:
Material characteristics
Conveying distance
Blower configuration
Pipeline design
This makes the system suitable for both small-scale and large-scale production facilities.
Suitable for:
PVC resin powder
Calcium carbonate
Additives
Fillers
Pigments
Chemical powders

Customized plastic formulations
The system utilizes:
Six-stage filtration design
Special filter cartridge protection
Large filtration area
Advantages include:
Superior dust collection efficiency
Extended filter lifespan
Stable vacuum performance
Reduced maintenance requirements
The filter assembly adopts a quick-open structure for:
Fast cleaning
Easy inspection
Reduced downtime
Simplified maintenance
This is especially beneficial in facilities processing fine PVC powders and dusty materials.
The vacuum loader can be integrated with:
Automatic weighing systems
Gravimetric dosing systems
Mixing units
Extrusion lines
Centralized feeding systems
Achieving a fully automated material handling process.
