  • Drop plate feeder
    Patent number: 6742679
    Abstract: A rotary plate feeder valve for use in pressurized pneumatic conveying systems. The valve comprises a rotary plate that is fed from a central inlet and discharges through a central outlet located immediately below the inlet. Located over the outlet discharge and within the valve body is a feed-rate control cone. Material transfer is controlled by rotary speed and feed-rate cone position. Several embodiments of the valve are disclosed including a “live-bottom” embodiment designed to reduce or eliminate bridging in silos. Due to high clearances within the valve, the valve may be used with abrasive materials, delicate materials and foodstuffs.

  • Rotary plate feeder
    Patent number: 6416261
    Abstract: A rotary plate feeder valve for use in pressurized pneumatic conveying systems. The valve comprises a rotary plate that is fed from a central inlet and has one or more discharge outlets. Material transfer is controlled by rotary plate speed, depth of deposit of material from the inlet onto the rotary plate, and by plows that move in or out along the rotary plate thus plowing material from the plate into an associated discharge port. Due to high clearances within the valve, the valve may be used with abrasive materials, delicate materials and foodstuffs.
