    Abstract: The present invention relates to a measuring device for refiners having refining discs (1, 2) that define between them refining gaps (3) for refining material on bars (5, 6) arranged between the disc (1, 2), said bars extending across the refining zones (4) of the refining discs. At least one bar is in the form of a sensor bar (6) designed to sense the load (9) exerted on the sensor bar (6) at a number of measuring points along the bar (6) during refining.

    Abstract: PCT No. PCT/SE91/00599 Sec. 371 Date Feb. 26, 1993 Sec. 102(e) Date Feb. 26, 1993 PCT Filed Sep. 11, 1991 PCT Pub. No. WO92/05874 PCT Pub. Date Apr. 16, 1992.A bearing system in a refiner for making pulp, where the raw material is refined in a refining gap between at least one pair of refining members (22, 24) rotating relative to one another, where at least one of said refining members (24) is supported by an axially movable and rotary shaft (26 ). The bearing system comprises a combined hydrostatic/hydrodynamic axial bearing arrangement and consists of a cylindric housing (32) with at least one rotary cylindric piston (30), which is mounted on the rotary shaft (26) for rotating together with the same. At least one outer and one inner concentric ring cylinder (200, 202 and, respectively, 210, 212) are arranged to abut one of the end surfaces of the rotary piston (30), so that a sealing gap is formed. The inner and the outer ring cylinder are axially movable but not rotary and are supported by a stationary ring piston (29 and, respectively, 33) located between said ring cylinders, and the area of the cavity (213 and, respectively, 214) formed between the inner and the outer ring cylinder is greater toward the ring piston (29 and, respectively, 33) than toward the end surface of the rotary piston (30). Channels (246 and, respectively, 248) are provided for supplying said cavity with a hydraulic pressure medium.
