<p>Grinding apparatus (10) has a grinding disc (18) grinding a tool (14), both of which are washed with coolant from a hose (26). The coolant collects in a funnel (10) and enters a separation channel (40) comprising a labyrinthine path (46) over a magnetised floor plate (46). Tungsten carbide is faintly responsive to a magnetic field and can be drawn out of suspension thereby. <IMAGE></p> |
