Higher Speed Mixer

The SUHUI high speed mixer is a versatile industrial blending machine designed for the rapid mixing, heating, and drying of plastic, rubber, chemical, and food-grade powder or granulate materials. Using a high-speed rotating impeller, it generates intense friction and shear force to achieve uniform blending in a fraction of the time required by conventional mixers.

Typical applications include the production of PVC dry blend, filling and modification of plastics, pre-mixing of compounding processes, and preparation of Wood-Plastic Composite (WPC) premixes. The machine is widely used in plastic pipe, profile, and sheet production lines as an essential upstream processing unit.

SUHUI high speed mixers are available as standalone hot mixers or as a combined hot/cold mixer system. The hot mixer heats and blends the material while the cold mixer rapidly cools it, preventing agglomeration and preparing the compound for direct feeding into extruders or pelletizers.

Key Features of SUHUI High Speed Mixer

• High-Speed Impeller Design: Generates strong friction heat and shear force for rapid, uniform mixing of powder and granulate materials.
• Hot/Cold Mixer Combination: Integrated hot mixing and forced cooling units ensure material is ready for downstream processing immediately.
• Precise Temperature Control: Multi-zone temperature sensors and automatic discharge control prevent material degradation during mixing.
• Stainless Steel Construction: All contact surfaces are made from polished 304 stainless steel, ensuring hygiene and corrosion resistance.
• Efficient Discharge System: Quick-open pneumatic discharge valve allows fast, complete material transfer with minimal residue.
• PLC Control Panel: Touchscreen interface for easy setting of mixing time, temperature, and speed parameters.
• Low Energy Consumption: Optimized impeller geometry and motor configuration reduce power consumption compared to conventional mixers.
• Wide Material Compatibility: Suitable for PVC, PP, PE, ABS, and WPC compounds with powder, granulate, or mixed feeds.

Typical Applications

• PVC dry blend production for pipe, profile, and cable compound manufacturing
• Color masterbatch and filler blending for plastics modification
• Pre-mixing of stabilizers, plasticizers, and lubricants before extrusion
• Wood-Plastic Composite (WPC) material preparation
• Rubber compound pre-mixing and drying
• Food-grade powder blending and drying applications

How the High Speed Mixer Works

1. Material Loading: Plastic powder or granulate materials, along with additives such as stabilizers, lubricants, and colorants, are loaded into the hot mixer bowl.
2. High-Speed Blending: The impeller rotates at high speed, generating friction heat that raises material temperature while achieving thorough, uniform mixing.
3. Temperature Monitoring: Sensors continuously monitor bowl temperature. When the set temperature is reached, the control system triggers automatic discharge.
4. Transfer to Cold Mixer: The hot, blended material is discharged into the cold mixer where a cooling jacket rapidly reduces temperature to prevent agglomeration.
5. Cooling & Discharge: Once cooled to the target temperature, the finished compound is discharged and conveyed to the extruder, pelletizer, or storage silo.

Frequently Asked Questions

What materials can the SUHUI high speed mixer process?

The SUHUI high speed mixer is suitable for PVC, PP, PE, ABS, and WPC compounds in powder, granulate, or mixed feed form. It is widely used for PVC dry blend production, color masterbatch and filler blending, stabilizer and lubricant pre-mixing, Wood-Plastic Composite (WPC) preparation, rubber compound pre-mixing, and food-grade powder blending and drying applications.

What is the difference between a standalone hot mixer and a hot/cold combination system?

A standalone hot mixer heats and blends the material using high-speed impeller friction but does not cool the output. A hot/cold combination system pairs the hot mixer with a cooling mixer that rapidly reduces material temperature after blending, preventing agglomeration and preparing the compound for immediate feeding into extruders or pelletizers without additional cooling time.

How does the high speed mixer achieve uniform blending so quickly?

The high-speed rotating impeller generates intense friction and shear force that simultaneously heats and blends materials. This friction-induced heating replaces external heat sources for most applications, while the high shear force ensures thorough, uniform distribution of additives, colorants, and fillers throughout the base material in a fraction of the time required by conventional paddle or ribbon mixers.

How is material discharge controlled in the high speed mixer?

Material discharge is controlled automatically by the PLC system based on temperature setpoints. When the mixed material reaches the target temperature, the control system triggers automatic opening of the pneumatic discharge valve, transferring the blended compound to the cooling mixer or downstream equipment. This automatic temperature-based discharge control prevents overheating and material degradation.

What hygiene and corrosion resistance standards does the mixer meet?

All material-contact surfaces of the SUHUI high speed mixer are made from polished 304 stainless steel, ensuring corrosion resistance and hygienic operation. The stainless steel construction is suitable for both plastic compound production and food-grade powder blending applications. The smooth polished interior minimizes material adhesion and simplifies cleaning between production runs.

What capacity options are available for the high speed mixer?

SUHUI high speed mixers are available in a range of bowl capacities to suit different production volumes, from laboratory-scale units to large-scale industrial configurations. Standalone hot mixers and hot/cold combination systems are both available. SUHUI engineers can recommend the appropriate capacity and configuration based on your material type, batch size, and downstream processing requirements.
