Abstract
A die lube recovery and recycling system includes a weir tank, a filtration assembly, and a holding tank. The weir tank receives used, dirty die lube and filters large particles therefrom. Preliminarily filtered die lube is pumped through the filtration assembly and reconditioned die lube is delivered to the holding tank. A level of reconditioned die lube in the holding tank is monitored and, the die lube is replenished with fresh die lube from a fresh die lube source when the level falls below a predetermined level. A die lube pressure booster is used to withdraw die lube from the holding tank, pressurize the withdrawn die lube, and spray the pressurized die lube on a die in a casting machine.
