PURPOSE: Provided is an arrangement for providing continuous grinding in a pulp grinder comprising a grindstone, a feed chute extending to the grindstone, a piston for pressing the wood in the feed chute against the grindstone, and a closing member that can be moved crosswise of the feed chute to prevent the wood from moving backward from the grindstone when the piston is moved away from the grindstone. CONSTITUTION: An arrangement provides continuous wood supply to the grindstone and is characterized by comprising an apparatus for providing continuous grinding of wood in a pulp grinder, the apparatus comprising: a grindstone; a feed chute extending to the grindstone for feeding wood therein to the grindstone along a feed direction, the feed chute defining a width extending across the feed direction; a piston movable between an extended position for pressing the wood in the feed direction against the grindstone and a withdrawn position for loading additional wood into the feed chute; at least one rotary feed member positioned to engage the wood in the feed chute disposed between the piston and the grindstone and push the wood toward the grindstone; and a closing member movable across the feed chute at a position between the piston and the rotary feed member, the closing member being movable across the entire width of the feed chute when the piston is in the extended position to provide constant and uninterrupted pressing of the wood across the entire width of the feed chute even during loading of additional wood into the feed chute.
