<p>Method and apparatus for making pulp of grinding goods, such as fibre material, in the grinding zone of a grinding apparatus by pressing it against a grinding surface (10) provided with a pattern (16) extending in the direction of movement of the grinding goods over the grinding surface for desintegration of the grinding goods. Steam generated during the grinding work causes a pressure rise along the grinding surface. The region for the maximum pressure in the grinding zone is established with the aid of measurements of the pressure course in the grinding zone and the pattern is formed in a predetermined region around this pressure centre so that braking of the grinding goods will be obtained.</p> |
