Abstract
An arrangement for removing chips from a machining coolant prior to filtering out the finer solids in a main filter. A coarse weave belt is frictionally driven along a strainer bottom wall of an auxiliary tank suspended above the main filter tank, the permanent media belt of a coarse weave which allows the liquid and suspended finer solids to pass through while capturing the chips. A powered drag conveyor frictionally engages and drives the permanent media belt through the auxiliary tank, each diverging when returning across the top and bottom respectively of the auxiliary tank prior to being recirculated through the auxiliary tank.
