EXTRUTEX VC Series Automatic Conveying & Material Handling System

Intelligent Pneumatic Conveying Solutions for PVC Powder, Limestone, Dry Blend & Plastic Granules

Modern plastics manufacturing requires continuous production without interruptions. Every moment that an extruder, mixer, or compounding system waits for raw material reduces productivity and increases operating costs. The EXTRUTEX VC Series Automatic Conveying & Material Handling System has been developed to solve these challenges through a fully automatic pneumatic conveying solution capable of transporting PVC resin, PVC dry blend, limestone powder, recycled materials, and plastic granules safely and efficiently.

The VC Series combines vacuum conveying technology, high-capacity storage hoppers, pulse-jet dust filtration, intelligent level monitoring, and automatic cleaning into one integrated material handling solution. Whether installed on a single production line or connected to a complete central conveying network, the system ensures stable material flow while minimizing operator intervention.

Designed for demanding industrial environments, the VC Series creates cleaner production areas by reducing airborne dust while maintaining consistent material delivery throughout long production cycles.

Automatic Material Handling for Modern Plastic Factories

Raw material handling is one of the most important stages of plastics manufacturing. PVC processing plants generate significant amounts of fine powder during material transfer, and manual loading often creates dust contamination, inconsistent feeding, and unnecessary labor costs.

The EXTRUTEX VC Series eliminates these problems through an enclosed vacuum conveying process that transfers materials directly from storage silos, mixers, or bulk bags into processing equipment without exposing operators to airborne dust.

The automatic conveying process includes:

• Material pickup from storage
• Vacuum transportation through pipelines
• High-efficiency pulse-jet filtration
• Storage hopper accumulation
• Automatic discharge into receiving equipment
• Continuous material level monitoring

This automated workflow improves productivity while creating a cleaner and safer production environment.

Typical Applications

The VC Series has been designed for numerous material handling applications throughout plastics processing plants.

PVC Dry Blend Conveying

PVC powder requires careful handling to avoid dust leakage and material loss. The VC Series transports dry blend directly to mixers, dosing systems, and extrusion equipment while maintaining clean factory conditions.

Limestone Powder Transfer

Calcium carbonate and limestone fillers can be transferred efficiently through the vacuum conveying system with minimal dust generation.

Plastic Granule Feeding

The system is equally suitable for polyethylene, polypropylene, ABS, PET, and engineering plastic pellets.

Central Material Distribution

Multiple VC units can be integrated into centralized feeding systems supplying several production lines simultaneously.

Compounding Plants

The VC Series supports continuous feeding of resins, additives, fillers, and recycled materials for compound manufacturing.

How the Pneumatic Conveying System Works

The EXTRUTEX VC Series operates using negative pressure generated by a high-performance vacuum pump. Material is drawn through conveying pipelines from storage toward the receiving hopper. Inside the filtration chamber, the conveying air passes through a large filter area while solids remain inside the storage hopper.

The pulse-jet cleaning mechanism periodically injects compressed air in the reverse direction, removing accumulated dust from the filter surface without interrupting conveying. Clean air continues toward the vacuum pump while material is automatically discharged into the receiving equipment once sufficient volume has accumulated.

This fully automatic cycle repeats continuously throughout production, ensuring stable material delivery with minimal maintenance.

Main Components of the VC Series

Vent Pulse-Jet Filtering Unit

The filtration unit provides high dust collection efficiency while maintaining stable airflow during continuous conveying. Automatic reverse compressed-air pulses clean the filter surface without requiring manual intervention.

Advantages include:

• Continuous filtration performance
• Low pressure loss
• Automatic cleaning
• Reduced maintenance
• Long filter service life

Storage Hopper

The storage hopper temporarily holds material before discharge into the receiving equipment. Its conical design promotes smooth material flow while minimizing bridging and material retention.

Available capacities range from compact production systems to large industrial installations, with custom sizes available upon request.

Vacuum Pump

The vacuum pump generates stable negative pressure for continuous material transportation over extended conveying distances while maintaining reliable operation during long production cycles.

Control Panel

The intelligent control panel manages conveying cycles, filter cleaning, level monitoring, alarms, and operating parameters, allowing fully automatic production with minimal operator involvement.

Intelligent Material Monitoring

Material starvation can interrupt production and reduce product quality. The VC Series continuously monitors material levels and automatically initiates conveying cycles whenever replenishment is required.

The control system provides:

• Automatic low-level detection
• Timely refill operation
• Continuous production
• Alarm notification
• Adjustable operating parameters

This intelligent automation significantly reduces manual supervision while improving production reliability.

Dust-Free Factory Operation

PVC processing environments generate large amounts of airborne powder during manual handling. The VC Series helps create cleaner production areas by eliminating manual bag dumping and containing dust inside a closed conveying system.

Key benefits include:

• Reduced airborne dust
• Cleaner equipment
• Improved worker safety
• Lower housekeeping requirements
• Better production hygiene

Energy-Efficient Vacuum Conveying

Because only the required amount of material is transported during each conveying cycle, unnecessary energy consumption is minimized. Combined with automatic filter cleaning, the system maintains efficient airflow throughout production.

The result is stable vacuum operation, efficient conveying cycles, reduced energy loss, and lower operating costs.
