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.
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.
The metal chip Receiver/Filter unit located at terminal end of system. Highly abrasion resistant centrifugal receiver section located beneath pulse jet type filter receives and separates chips from the conveying system which is drawn through filter by the air flow developed by a downstream blower/exhauster unit.
