The Horizontal Screw Belt Mixer merges the conveying efficiency of screw agitators with the blending power of belt paddles, creating a versatile solution for mixed-phase materials. Its horizontal trough (200L - 5000L) contains a central screw that transports materials axially, while an outer belt agitator with radial paddles disrupts flow, ensuring uniform blending of powders, granules, and semi-dry pastes. This dual-action design eliminates segregation in density-differentiated mixtures (e.g., light flours and heavy metal powders), making it ideal for industries requiring consistent blends with minimal operator intervention.

Discharge Mode | Manual or pneumatic butterfly valve (150 - 300mm diameter) |
Dual-Action Mixing: Screw and belt agitators work synergistically to achieve 99.6% uniformity in density-differentiated mixtures (e.g., 0.5 g/cm³ talc and 7.8 g/cm³ iron powder). This outperforms single-agitator mixers by 5 - 8% in uniformity.
Self-Cleaning Design: Trough inner surface with polished finish (Ra < 0.8μm) and agitator geometry leave < 0.5% residual material after discharge, reducing cross-contamination risks in multi-product facilities.
Scalable Design: Modular construction allows easy capacity expansion (e.g., upgrading from 1000L to 2000L by adding trough sections) without replacing the entire drive system, saving 30% on equipment costs.
Low Noise: Vibration-damping mounts and precision-balanced agitators reduce operating noise to < 85dB, compliant with OSHA 1910.95 noise exposure limits for 8-hour shifts.
Versatile across industries handling complex mixtures:
Chemical Industry: Blending pigments (titanium dioxide) with carrier powders (calcium carbonate) for masterbatches with 20 - 50% pigment loading, ensuring color consistency (ΔE < 1 per CIELAB). Mixing surfactants with builders in detergent powders.
Plastics Recycling: Mixing regrind plastic pellets (PP/PE mix) with virgin resins (90:10 ratio) and UV stabilizers, achieving melt flow consistency ±5% for extrusion processes.
Cosmetics: Blending talc (bulk density 0.8 g/cm³) with mica (0.3 g/cm³) for powder foundations, ensuring uniform coverage and color payoff (tested via spectrophotometry).
Mining: Preparing mineral concentrates (e.g., copper ore with 20% Cu) with flotation reagents (xanthates, frothers) for consistent recovery rates (85 - 90% in processing plants).
Energy Savings: Optimized motor sizing and agitator design reduce power consumption by 18 - 22% compared to conventional mixers. The independent VFDs allow speed tuning for specific materials, avoiding over-energy use.
Durability: Screw and belt components made from Hardox 400 wear-resistant steel (hardness 400 HB) extend service life by 2 - 3 times compared to mild steel, reducing replacement costs in abrasive applications.
Flexibility: Compatible with liquid addition systems (spray nozzles with 0.5 - 2.0mm orifices) for moisture-controlled blending (e.g., adding 5 - 10% water to powder blends for agglomeration).
Warranty: Offer a 2-year warranty on all components, including motors and electronics. Our service team provides on-site repairs within 48 hours for critical breakdowns, minimizing production loss.
