Continuous Powder Blending System for Silo Discharge

Continuous Powder Blending System

For applications requiring consistent product blending during silo discharge, our continuous powder blending system integrates multiple feed streams into a single homogenized output. Unlike batch mixers, this system operates continuously, matching the flow rate of downstream equipment (packaging, loading, or further processing).

How It Works

Multiple screw feeders or rotary valves draw material from individual silos at metered rates. Each stream passes through a loss-in-weight or gravimetric feeder for precise dosing, then enters a static or dynamic mixing chamber where the materials are combined into a uniform blend.

Key Specifications

• Throughput: 5-200 tph continuous output
• Blend accuracy: ±1% of target ratio for each component
• Components: 2-6 simultaneous feed streams
• Control: PLC-based recipe management with automatic ratio adjustment

Applications

• Cement additive blending (clinker + gypsum + slag + limestone)
• Fly ash classification and blending
• Mortar dry mix production
• Chemical powder formulation
