Pneumatic Conveying Systems Types

Q1: What are the main types? A: Three types: -Suction: Uses vacuum for dust-free multi-point intake. -Pressure: Pushes materials via compressed air for long-distance (up to 1km) transport. -Hybrid: Combines both for complex needs. Q2: How by material density? -Dilute-phase: Low solid-air ratio (<10:1), high-speed airflow. -Dense-phase: High ratio (up to 100:1), slug flow for abrasive materials, less wear. Q3: How to choose? A: Depends on material traits (size/density), pipeline length, throughput, and energy efficiency (dense-phase saves energy for short hauls). Q4: Blockage prevention? A: Maintain airspeed, use smooth pipes/bends, install pressure sensors.
