High-Intensity Twin Shaft Paddle Mixers for Modern Building Materials

Continuous Dual Shaft Mixing Technology by PerMix

The construction industry is undergoing a transformation. From high-performance mortars and self-leveling compounds to advanced dry mix plasters, tile adhesives, fiber-reinforced concretes, and specialty cementitious products, modern building materials demand precision blending at a level never seen before.

As formulations become more technical, ingredient mixing is no longer just a step in the process — it is the foundation of product performance.

PerMix Twin Shaft High-Intensity Paddle Mixers are engineered specifically for the new generation of building materials, delivering continuous, uniform, and aggressive mixing for complex formulations.

Why High-Intensity Mixing Matters in Modern Construction Materials

Today’s dry mix and wet mix building materials often include:

• Polymer powders and latex modifiers
• Glass, synthetic, or carbon fibers
• Lightweight fillers and aeration agents
• Color pigments and mineral additives
• Silica fume and microfine powders
• Recycled or engineered aggregates

These materials vary widely in particle size, density, and flow behavior. Without proper shear and mechanical action, segregation, agglomeration, and inconsistent distribution can occur — directly impacting strength, curing behavior, adhesion, and final product quality.

PerMix continuous dual shaft paddle mixers solve this challenge.

How the PerMix Twin Shaft Paddle Mixer Works

The PerMix continuous dual shaft paddle mixer features two counter-rotating shafts fitted with specially engineered paddles that create:

• Intensive mechanical fluidization of the material bed
• High shear mixing zones for dispersion of additives
• Rapid homogenization across the full mixer length
• Continuous material movement from inlet to discharge

The counter-rotating paddle configuration ensures that materials are lifted, thrown, and intermeshed throughout the mixing chamber. This prevents dead zones and guarantees consistent blending, even for cohesive or fiber-rich formulations.

The result: uniform mixing in seconds, not minutes.

Advantages of Continuous Dual Shaft High-Intensity Mixing

PerMix twin shaft paddle mixers deliver:

• Continuous production capability for high throughput plants
• Superior dispersion of fibers and lightweight additives
• Reduced mixing time and energy consumption
• Elimination of batch inconsistencies
• Scalability for small specialty plants to large industrial operations
• Heavy-duty construction for abrasive building materials

For industries producing mortar, dry mix cement, plasters, grouts, tile adhesives, refractory mixes, engineered concrete blends, and specialty construction compounds, consistent mixing directly translates to market advantage.

Built for the Next Generation of Building Materials

As building standards evolve — including higher strength requirements, improved insulation values, faster curing times, and environmentally sustainable formulations — mixing precision becomes critical.

PerMix designs its twin shaft high-intensity paddle mixers with:

• Abrasion-resistant liners (Hardox, AR steel options)
• Heavy-duty shafts and bearings
• Customizable paddle geometry
• Variable speed control
• Integration with dosing, feeding, and discharge systems
• Dust-tight construction for dry powder handling

Each mixer is engineered based on your specific material characteristics and production goals.

Industries That Benefit

• Dry mix mortar manufacturers
• Tile adhesive producers
• Cement additive companies
• Concrete product manufacturers
• Refractory material producers
• Polymer-modified construction materials manufacturers
• Lightweight building material producers

The shift toward advanced building formulations demands more than conventional ribbon or tumble mixing. It demands controlled shear, mechanical energy, and uniform dispersion.

That is exactly what PerMix delivers.
