Product Description

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

Typical applications include PVC dry blend production, plastic filler modification, stabilizer and lubricant pre-mixing, color masterbatch preparation, and Wood-Plastic Composite (WPC) premix preparation. The machine is widely used before plastic pipe extrusion lines, plastic profile extrusion lines, sheet production lines, pelletizing systems, and other compounding processes.

SUHUI high speed mixers are available as standalone hot mixers or as hot/cold mixer combination systems. The hot mixer heats and blends the material, while the cold mixer rapidly reduces material temperature after discharge, preventing agglomeration and preparing the compound for feeding into extruders, pelletizers, or storage silos.

Typical Applications

The high speed mixer is commonly used in plastic compounding plants, PVC pipe and profile factories, WPC production, masterbatch preparation, and auxiliary processing before extrusion. It is especially useful when raw materials, fillers, pigments, stabilizers, lubricants, or modifiers need to be evenly distributed before entering the next production stage.

  • PVC dry blend production for pipe, profile, cable, and sheet compound manufacturing.
  • Color masterbatch, filler, and additive blending for plastic modification.
  • Pre-mixing of stabilizers, plasticizers, lubricants, pigments, and processing aids before extrusion.
  • Wood-Plastic Composite (WPC) premix preparation with wood powder, plastic resin, and additives.
  • Rubber compound pre-mixing, powder blending, and drying applications.
  • Food-grade powder blending and drying applications when suitable hygiene configuration is selected.

High speed mixer applications for PVC PP PE ABS WPC and masterbatch materials

SUHUI high speed mixers can process PVC, PP, PE, ABS, WPC premix, masterbatch, fillers, and other powder or granulate materials.

How the High Speed Mixer Works

  1. Material Loading: Plastic powder or granules, fillers, stabilizers, lubricants, pigments, and other additives are loaded into the hot mixer bowl.
  2. High-Speed Blending: The impeller rotates at high speed, creating friction heat and shear force while distributing additives throughout the base material.
  3. Temperature Monitoring: Sensors monitor the bowl temperature. When the set temperature is reached, the control system triggers discharge.
  4. Transfer to Cold Mixer: Hot blended material is discharged into the cooling mixer, where the cooling jacket and mixing action rapidly reduce temperature.
  5. Cooling and Output: After cooling to the target temperature, the finished compound is discharged for feeding into an extruder, pelletizer, silo, or bagging station.

The high-speed impeller generates friction heat and shear force, helping additives, fillers, and resin distribute evenly inside the mixing bowl.

Hot Mixer vs Hot/Cold Mixer Combination

A standalone hot mixer is suitable when the process only needs rapid heating and blending, or when the material can be cooled separately after discharge. A hot/cold mixer combination is better when the mixed compound must be cooled quickly to prevent agglomeration, sticking, discoloration, or process instability.

For PVC dry blend, WPC premix, and many extrusion-related applications, the hot/cold configuration is often recommended because it creates a more stable preparation process. The hot mixer completes friction heating and dispersion, while the cooling mixer reduces temperature before the material enters downstream equipment.

Temperature Control and PLC Automation

Stable mixing quality depends on controlling temperature, mixing time, impeller speed, and discharge timing. SUHUI configures PLC control systems to support automatic temperature-based discharge, operator parameter setting, alarm monitoring, and repeatable batch operation.

For heat-sensitive materials such as PVC compounds, temperature control is especially important. If the material is overheated, it can degrade, discolor, or stick inside the mixer. If the material is not mixed long enough, additives may not be fully dispersed, creating downstream extrusion instability.

PLC automation helps operators control temperature, mixing time, automatic discharge, and cooling preparation for repeatable batch quality.

Choosing the Right High Speed Mixer Configuration

The right high speed mixer configuration depends on material type, batch size, required heating temperature, cooling requirement, downstream equipment, and workshop layout. For example, PVC dry blend production often requires a hot/cold mixer combination, while some simpler powder blending applications may only need a standalone hot mixer.

Before quoting a mixer system, SUHUI engineers typically confirm the target material, formula type, batch capacity, required output, whether cooling is needed, discharge height, feeding method, and whether the mixer will connect to an extruder, pelletizing line, or storage system.

Related Plastic Processing Lines

High speed mixers are commonly installed upstream of plastic pipe extrusion lines, plastic profile extrusion lines, and plastic recycling pelletizing lines. For PVC applications, they are often used before a PVC pipe extrusion line or PVC profile extrusion line to prepare dry blend material.

Frequently Asked Questions

What materials can the SUHUI high speed mixer process?

The SUHUI high speed mixer can process PVC, PP, PE, ABS, WPC compounds, masterbatch, fillers, powders, and granulates. It is widely used for PVC dry blend, color and filler blending, additive pre-mixing, WPC preparation, rubber premixing, and selected food-grade powder applications.

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

A hot mixer heats and blends material using high-speed impeller friction. A hot/cold mixer system adds a cooling mixer after hot mixing, rapidly reducing material temperature to prevent agglomeration and prepare the compound for extrusion, pelletizing, storage, or packaging.

How does a high speed mixer achieve uniform blending?

The high-speed impeller creates friction heat and shear force inside the bowl. This movement disperses additives, pigments, fillers, and resin particles quickly, helping the material reach a more uniform blend before downstream processing.

How is material discharge controlled?

Material discharge can be controlled by the PLC system based on temperature and mixing time. When the material reaches the target condition, the pneumatic discharge valve opens and transfers the compound to the cooling mixer or downstream equipment.

Why are stainless steel contact surfaces important?

Polished stainless steel contact surfaces improve corrosion resistance, reduce material adhesion, support easier cleaning, and help maintain hygienic operation. This is important for plastic additives, powder blending, WPC premix, and selected food-grade material applications.

What information is needed before choosing a high speed mixer?

Key details include material type, formula, bulk density, batch size, required temperature, cooling requirement, downstream process, discharge height, automation requirement, and available workshop space. SUHUI can recommend the mixer model and hot/cold configuration based on these conditions.
