Pneumatic Conveying of Metal Chips Chip Feeder

Metal Chip Metering Feeder


Located at the machine tool, chips discharging from the machine tool conveyor are collected in a hopper shown in adjacent photo. A helicoid (screw) feeder located beneath the hopper uniformly meters metal chips into the pneumatic conveying line intake elbow shown at left, from which chips are drawn by vacuum into the conveying line.
Pneumatic Conveying of Metal Chips Pipeline branch Isolation Valve

Line Isolation Gate Valve


National Rotary Swing Gate Valve used for isolation of each vacuum pneumatic conveying branch pipeline. Note compression ring/spring feature, which assures an optimum seal when valve is in the closed position, is self relieving and prevents jamming.
