14.2 Stage 1 - magnetic separator filtration
Used or contaminated oil is discharged by a coolant chute at the left hand rear corner of the machine
base. This oil is directed by a coolant discharge tray into the entry portion of the magnetic separator.
A magnetic drum separator provides the first stage removal of all ferrous particles from the oil
returning back to the coolant system from the grinding process.
Waste debris extracted by the magnetic drum is discharged into a small sludge tank which is
positioned adjacent to the drum unit.
14.3 Stage 2 – centrifugal filtration
Semi-clean oil which has passed through the magnetic separator is then pumped into the centrifuge
unit where secondary extraction of unwanted particles, both metallic and non-metallic is carried out.
The centrifuge unit is fixed to a free standing support frame through anti-vibration mounts. The
support frame should be bolted to the floor to prevent any movement. A discharge bin fitted with
castors is positioned within the structure of the support frame and beneath the discharge outlet from
the centrifuge.
Clean, but warm oil is gravity fed from the centrifuge unit to the coolant system clean oil tank
through the large diameter transfer pipe.
14.4 Stage 3 – oil cooling
The cleaned oil fed from the centrifuge unit into the clean oil tank is then cooled down by the
submerged cooling coils of the Habor oil cooler unit located directly above the clean oil tank.
Oil temperature is controlled a local display panel fitted to the oil cooler unit. Temperature setting is
variable, but the standard setting for commissioning and shipment is set at 2°C below the ambient
temperature.
The cooled oil is mixed by natural convection as it get directed by baffle plates back to the main
coolant pump.
