<p>Wood is continuously processed by grinding wood in the presence of water with a rotating grinder in a pressurized gas-filled grinding chamber and forming a primary groundwood stock under superatmospheric pressure. The primary groundwood stock is passed to a stick crusher while maintaining the stock under superatmospheric pressure to produce a secondary groundwood stock. The secondary groundwood stock is then passed to a discharge valve, while maintaining the stock under superatmospheric pressure, and is continuously discharged through the discharge valve while preserving a hydraulic seal of secondary groundwood stock upstream of the discharge valve.</p> |
