Cementitious Mixers

Davis Cementitious Mixers are used for mixing both wet and dry cementitious products. We use our Double Ribbon Agitator whem mixing dry material since the ribbons rotate faster and are more efficient with ingredients that are very free flowing. We use our Paddle Agitator with wet cementitious products since this material is a heavy slurry with poor flow characteristics. Our paddles provide a lifting and folding mixing action. 

Fast, uniform blending of cementitious materials—designed for powders, small granules, bentonite and clays with paddle or ribbon agitation for precise control.

Key Benefits

• Consistent homogeneity: Engineered paddle and ribbon agitators ensure even dispersion of powders and fines.
• Low segregation: Gentle, controllable mixing prevents particle separation and maintains blend integrity.
• Short cycle times: Optimized geometry for fast throughput without overworking sensitive additives.
• Flexible configurations: Horizontal design with paddle or ribbon options to match material flow and shear requirements.
• Easy cleanout & maintenance: Sanitary finishes and accessible internals reduce downtime between batches.

Typical Materials Handled

• Cement (Portland, blended cements)
• Fly ash, slag (GGBFS)
• Silica fume, metakaolin
• Gypsum, lime, hydrated lime
• Bentonite, natural & processed clays
• Sand, fine aggregates, microsilica
• Acrylic, styrene–butadiene and other polymer additives (dry)
• Chemical admixtures (dry powders), accelerators, retarders
• Perlite, vermiculite, expanded mineral fillers
• Pigments, colorants, dry fibers, glass microbeads
• Zeolites, aluminates, specialty powders

Recommended Mixer Types & When to Use

• Paddle agitators: Best for higher-shear blending, deagglomeration, and dispersing binders into dense powders.
• Ribbon agitators: Ideal for gentle, low-shear blending of free-flowing powders and fragile additives where minimal particle damage is required.
• Horizontal configuration: Promotes uniform flow, simple discharge, and scalable capacities for continuous or batch operations.

Applications

• Precast concrete and block manufacturing
• Mortars, grouts, and dry-mix mortars
• Tile adhesives, cementitious coatings, and repair products
• Oil well cementing blends and specialty cement formulations
• Lightweight cementitious composites and insulating mixes
