Abstract: An arrangement for providing continuous grinding in a pulp grinder comprising a feed chute and a piston in the feed chute moving lengthwise of the feed chute for pressing the wood in the feed chute against a grindstone. The arrangement comprises rotary feed members between the piston and the grindstone on the sides of the feed chute for pushing the compressed wood further against the grindstone. Also, the arrangement comprises a closing member that can be pushed between the compressed wood and the piston to prevent the wood from moving backward with the piston as the piston is moved to the initial position, ready for the stroke, to allow the feed of a new batch of wood.

Abstract: A method of controlling a grinding process in a pocket grinder in which a batch of wood in at least one pocket is pressed against a rotating grindstone by a pressure shoe displaceable in the pocket. At predetermined intervals an apparently produced amount of pulp is calculated at separate measuring points of the grinding stroke of the pressure shoe and the specific energy consumption calculated on the basis of this amount of pulp is compared to a target figure for the specific energy consumption. The batch grinding is adjusted depending on a deviation of the specific energy consumption from the target figure. The compaction of the batch in the pocket during the stroke of the pressure shoe is taken into account in the grinding adjustment by correcting the calculated apparently produced amount of pulp in relation to a change in the density of the batch to be ground so that the fluctuations in the fineness of the pulp produced at separate measuring points of the pressure shoe are maintained as small as possible during the grinding stroke of the pressure shoe.
