A method of beating fibre slurries, such as paper pulp, and lump-goods, such as wood-chips and shavings. The good are subjected to repeated, rapid pressure pulsations and working moments of short duration. This is obtained by causing the hydraulic pressure to increase during a compression phase with increasing internal frictional co-action between individual fibres, whereafter said hydraulic pressure is caused to fall momentarily during a following expansion phase. |
