Metal chips and turnings are fed to a receiving hopper (RH) from which they are drawn down into crusher/shredder (CR) for size reduction so as to be suitable for pneumatic transport. Crusher discharge is directed by gravity to helicoid metering conveyor (HC) which discharges into rotary air lock feeder (RAF). Metal chips discharged from the feeder fall into pipeline (PP) where air flow generated by pressure blower unit (PBU) carries the material downstream to target box (TB) where flow velocity is dissipated, allowing chips to discharge by gravity into a container or truck.
