This technology solves key problems in paste backfill systems: deep cone thickener rake jamming, insufficient material storage, and lack of real-time pipeline monitoring.

Core innovations:

Ultra-high recirculation secondary feed – reduces torque risk, boosts storage capacity by >200%

Wide-angle, large-area fluidized steady discharge – prevents dead mud buildup, enables stable high-concentration, high-flow backfill (>120 m³/h)

Dedicated mine-use deep cone thickener with anti-jam protection

Pipeline safety monitoring system – real-time pressure (±0.5% FS), flow, concentration; predicts blockages and leaks; reduces underground inspection labor by >50%

Performance:

Backfill concentration stability: ±2%

Flow rate: >120 m³/h

Material storage capacity increase: >200%

Inspection personnel reduction: >50%

Applied at multiple non-ferrous mines. Proven reliable, safe, and efficient for large-scale paste backfill operations.
