Metal Chip Conveyors

Drag Flight Metal Chip Conveyors

Used for conveying broken, crushed or finely sized metal chips only. Suitable for both horizontal and vertical runs. The usual configuration is a rectangular trough fitted with a single strand or two parallel strands of chain to which drag flights are fitted to provide the conveying mechanism.

  • Not recommended where stringy (bushy) turnings are present as these will cause jamming of the drag chains.
  • Low linear strand speed results in low friction wear for increased service life

Helicoid (Screw) Metal Chip Conveyors

Screw conveyors are suitable for short horizontal or inclined runs.

  • They can be used to convey both metal chips and turnings.
  • Single and double flight designs are commonly used.
  • Excellent choice when screw conveyor is used as a controlled rate feeder.

National’s design features the following

  • Constant thickness, abrasion resistant helicoid flights
  • Continuously welded flights to  pipe shaft.
  • Oversized  heavy wall central pipe for reduced deflection

Hinged Steel Belt Metal Chip Conveyors

The hinged steel belt conveyor (frequently called an Apron Conveyor) is useful for a wide range of horizontal and inclined conveying runs where metal chips or stringy metal turnings are being handled.

National’s design features the following

  • Tightly formed hinge loops
  • Fully welded side wings to preclude problems encountered with conventional steel belt designs.
  • Heavy duty tracks fabricated with abrasion resistant steel

Push Bar Metal Chip Conveyors

Plow mechanisms fitted to a reciprocating stroke (push-pull) shaft assembly move metal chips or bushy metal turnings in the desired direction

  • The reciprocating shaft and plow mechanism is  driven by a hydraulic power unit..
  • Can handle large volumes of  chips, turnings and coolant.
  • Normally installed at or below floor level.
  • Coolant removal may be aided by use of wedge wire screen panels placed at selected locations, draining into a sub trough.
