Complete Solutions for High-Viscosity Material Mixing: The 15L Vacuum Double Planetary Mixer

Manufacturers of high-viscosity materials—lithium battery slurries, adhesives, sealants, cosmetics, and pharmaceuticals—face significant processing challenges:

1. Material viscosity: Products from 10,000 to 1,000,000 cps don't flow easily

2. Particle dispersion: Agglomerates must be broken down to achieve uniformity

3. Air incorporation: Mixing inevitably traps air, degrading product quality

4. Scale-up difficulty: Laboratory results don't always transfer to production

5. Cross-contamination: Different formulations require thorough cleaning

6. Process control: Consistent results demand precise parameter management

The 15L Vacuum Double Planetary Mixer is engineered to solve these challenges, providing a versatile solution for small-to-medium production.

Solution Overview

The 15L model integrates multiple functions in a single system:

Complete Mixing Head Configurations

MAXWELL offers customized mixing head combinations for different applications:

High-speed + High-speed:

• Maximum shear for particle size reduction

• Best for dispersing challenging powders in liquids

High-speed + Low-speed:

• Balanced dispersion and bulk mixing

• Ideal for sealants, adhesives, and battery slurries

Low-speed + Low-speed:

• Gentle mixing for shear-sensitive materials

• Suitable for creams, gels, and pharmaceutical products

Turnkey Integration

The 15L mixer can be integrated with other equipment for complete production lines:

Typical System Components:

1. Material preparation: Heating/cooling tanks for raw materials

2. The 15L Vacuum Double Planetary Mixer: Core mixing operation

3. Discharge system: Transfer pump or discharge valve

4. Storage: Holding tanks for finished product

5. Quality control: Sampling port and monitoring systems

6. Filling: Integration with filling equipment

Industry-Specific Solutions

Lithium Battery Production

Challenge: Battery slurries require exceptional uniformity and bubble-free material. Active materials, conductive additives, and binders must be dispersed perfectly.

Solution: The 15L mixer's high-speed dispersion disc (2980 rpm) breaks down agglomerates while the vacuum system ( -0.09 MPa) eliminates air bubbles. Multi-stage programming enables dry mixing, binder addition, and final dispersion in a single cycle.

Sealant and Adhesive Production

Challenge: Sealants and adhesives are high-viscosity materials that require thorough mixing of base polymers, fillers, and additives.

Solution: The double planetary motion ensures macro-scale mixing, while the high-speed disperser handles fine dispersion. The scraper system ensures no material remains on vessel walls. Temperature control maintains optimal processing viscosity.

Cosmetics and Pharmaceuticals

Challenge: Creams, lotions, and ointments must be perfectly smooth with no air bubbles and consistent particle size.

Solution: The 15L mixer's gentle mixing capability combined with vacuum degassing produces creamy, bubble-free products. Stainless steel construction ensures sanitary processing.
