Shandong Yude Plastic Machinery Co., Ltd. offers professional vertical mixing equipment specifically designed for polystyrene pellets. Our mixer handles GPPS, HIPS, and recycled PS materials with precision. It ensures uniform blending while preventing static buildup and material degradation. Your production line deserves equipment that maintains consistency and quality. Our PS Plastic Mixer delivers exactly that performance.
Our vertical polystyrene mixer uses advanced engineering principles. The conical chamber design creates optimal flow patterns. Your materials move in a controlled spiral motion that prevents separation.
The slow-rotating spiral screw operates at 10-25 rpm. This gentle action preserves pellet integrity. You won't see the yellowing or thermal stress that affects other mixers.

Operational Benefits


The working principle focuses on gentle material handling. Materials enter the conical chamber through the top inlet. The spiral screw lifts pellets upward along the chamber wall.
Gravity then allows materials to cascade down naturally. This creates a tumbling action that ensures thorough mixing. The process continues until you achieve perfect uniformity.
The chamber's polished surface prevents material sticking. Your additives distribute evenly throughout the batch. This eliminates hot spots and color streaking in your final products.
You can mix GPPS for disposable containers and utensils with the PS Plastic Mixer. The mixer handles nucleating agents for foam production. Your food-grade materials stay contamination-free.
HIPS blending for appliance housings works perfectly. You can incorporate flame retardants and UV stabilizers. The mixer ensures consistent impact resistance properties.
Blend virgin PS with regrind materials effectively. The mixer handles density differences between materials. Your recycled content integrates smoothly with new resin.
Mix colorants for toys and household items. The equipment handles transparent GPPS applications. You get consistent color matching across production runs.
Loading Sequence
Load your base PS pellets first. Add masterbatch or additives on top. This sequence ensures better coating distribution.
Timing Considerations
Keep mixing cycles under 40 minutes. Longer cycles can cause thermal stress. Monitor your batch temperature during operation.
Cleaning Procedures
Use dry cleaning methods only. Never introduce water near electrical components. Regular maintenance extends equipment life.
Safety Protocols
Always ground the equipment properly. This prevents static discharge incidents. Check safety systems before each operation.
