ABSTRACT:
The disclosure relates to apparatus for producing mechanical wood pulp of the type having a grinding stone with at least one wood supply chute in which the wood which is to be ground is pressed onto the grinding stone. A trough or a collecting channel is placed underneath the grinding stone. A water supply device moistens the grinding stone at the grinding zone. At least one closed water tank is set up on the grinding stone in front of the wood supply chute, viewed in the direction of rotation of the grinding stone. The water tank is sealed at least on the side furthest away from the supply chute. The tank has a supply line for pressurized water and has outlet holes directed toward the surface of the stone. Preferably, sealing of the water tank is effected by a sealing plug at the grinding stone which plug is adjustable with respect to the grinding stone to accommodate wear of the plug from the stone.
