表格
| Type | Working Principle | Core Advantages | Main Limitations | Typical Application |
|---|---|---|---|---|
| Vertical Mixer | Screw lifts materials from tank bottom to top, then materials scatter in umbrella‑shaped flow to realize vertical circulating mixing. | Small footprint, large capacity (0.5‑15 tons), low power consumption, labor‑saving; fast and uniform mixing; convenient feeding at ground level. | Poor performance for micro‑quantity or ultra‑high‑precision mixing compared with dedicated units. | Large‑batch material mixing, formula mixing before plastic granulation, regrind processing, centralized feeding in injection‑molding workshops. |
| Horizontal Mixer | Materials are driven by paddle or ribbon agitator inside horizontal cylinder to achieve circulating mixing. | Fast and uniform mixing; handles sticky materials or materials with minor liquid content; tilt‑able cylinder for easy discharging and cleaning. | Larger floor space than vertical type; limited for materials with poor flowability or high stickiness. | Plastic product processing, powder‑pellet blending, solid‑liquid mixture mixing. |
| High‑Speed Mixer | High‑speed rotating paddles (up to 3000 RPM) generate frictional heat and complete intensive rapid mixing. | Ultra‑fast mixing speed (3‑6 minutes per batch); supports heating or cooling; suitable for small‑batch materials with wide component‑ratio range. | Limited batch capacity (200‑2500 L per batch). | PVC compounding, masterbatch production, pre‑treatment before plastic modification, processes requiring heating and drying. |
| Gravimetric Mixer | High‑precision load cells weigh each raw material accurately and discharge materials according to preset ratios for blending. | Ultra‑high batching accuracy (up to ±0.1 %); auto‑calibration and up to 50‑recipe storage; stable mixing quality. | High equipment cost and relatively complex structure. | Precision injection molding, extrusion, blow molding and other scenarios requiring strict batching accuracy. |
| Tumbler Mixer | Materials tumble and blend inside rotating drum relying on gravity. | Simple structure, low cost, low rotating speed & low power; minimal material abrasion. | Relatively low mixing efficiency; less convenient for cleaning and material change‑over. | Mixing regular‑shape pellets with moderate mixing‑strength requirement. |
Special note: Large‑scale plastic‑production or modification plants also adopt multi‑bin blending silos and wall‑attachment blending silos. These static/gravity‑type mixing devices have volume above 1000 m³, used for homogenizing large batches of finished pellets to guarantee consistent material properties.
Core Specifications: Hard Indicators for Selection
After confirming equipment type, select proper specifications with following key parameters:
Working Capacity / Mixing Volume (kg or L): Material handling capacity per batch or per hour, core indicator for production throughput. ‑ Vertical mixer: Common sizes 50 kg, 100 kg, 200 kg; large‑size models reach 1‑15 tons. ‑ Horizontal mixer: Common sizes 100 kg, 150 kg, 200 kg; maximum capacity above 1 ton. ‑ High‑speed mixer: Batch capacity 200‑2500 L per batch. ‑ Gravimetric mixer: Hourly throughput 80‑200 kg (Model SGB‑600‑3).
Selection tips: Select according to batch or hourly processing requirement; keep actual working load below rated capacity with reasonable margin.
Motor Power (kW): Determines driving power and energy consumption. ‑ Vertical mixer (100 kg): approx. 3 kW ‑ Horizontal mixer (200 kg): approx. 4 kW ‑ High‑speed mixer: Power varies greatly among different models, confirm according to specific equipment.
Energy reference: Higher power brings larger throughput yet higher energy consumption.
Mixing Speed (rpm): Influences mixing speed and blending result. ‑ Standard vertical / horizontal mixer: 45‑62 rpm (VCG series 62 rpm, GLT series 45 rpm). ‑ High‑speed mixer: 600‑3000 rpm.
Reference: Medium‑low rotation speed satisfies common pellet mixing; choose high‑speed unit for fast intensive mixing or heating‑assisted processes.
Heating Function: Some mixers integrate heating‑drying function to remove moisture during mixing. Heating modes: Electric heating, hot‑air heating, oil heating. Application scenario: Select heated models for highly‑hygroscopic raw materials such as Nylon and PET or processes with strict dryness requirements.
Material & Construction: Directly affect durability and cleaning convenience. Main material: Material‑contact components are mostly SUS304 stainless steel for anti‑rust and easy‑clean performance. Structural details: Polished tank body and detachable mixing paddles facilitate cleaning and material change‑over.
Safety Configurations: Basic configurations include motor overload protection, open‑cover auto‑stop, emergency stop button and interlock safety devices.
Control & Accuracy: Core indicator for high‑end models. ‑ Gravimetric mixer: Micro‑computer control system, maximum accuracy ±0.1 %, supports 50‑group recipe storage and auto‑calibration. ‑ Conventional mixers: Equipped with adjustable timer (0‑30 minutes or 0‑300 hours).
Selection Guidelines
Follow clear logic for plastic mixer selection:
‑ Determine equipment type by material state: Pellets, flakes, regrind: Vertical mixer is general‑purpose option with good cost‑performance and large capacity. Powder‑dominated feed, minor liquid content or sticky materials: Horizontal mixer or high‑speed mixer delivers better performance. Heating‑drying required: Choose high‑speed mixer or heated vertical / horizontal mixer. Ultra‑high batching‑accuracy requirement: Adopt gravimetric mixer.
‑ Determine specification by throughput: Select working capacity and motor power according to batch or hourly processing demand. Vertical large‑capacity mixers for large‑volume low‑frequency batches; horizontal or high‑speed mixers for small‑volume frequent batches.
‑ Determine structure by installation space: Limited floor space, vertical layout preferred: vertical mixer. Limited workshop height, easy discharging & cleaning required: tilt‑cylinder horizontal mixer.
‑ Judge quality by material and safety: Prioritize stainless‑steel material especially for material‑contact parts to avoid contamination and simplify cleaning. Verify safety features such as overload protection and open‑cover auto‑stop to protect operators.
‑ Consider automation & control requirements: For precise recipe control, data logging and multi‑recipe storage: select gravimetric mixer with micro‑computer system. General‑purpose applications: basic timer‑equipped units are sufficient.
