    Description

    The Jokro-Mill, according to Jonas/Kross, allows simultaneous, reproducible beating of up to 6 pulp samples of 16 grams each. The beating units (bronze) are mounted in a turntable and perform a planetary movement around the central shaft. Centrifugal force is causing the beater roll inside each vessel to roll along the sides with the pulp in between, thereby causing the beating action. The speed of the turntable is controlled electronically, therefore the beating load remains constant.


    Test description

    Soaked and disintegrated samples of 16 g (o.d.) at a concentration of 6% are spread evenly around the inside walls of the beating vessels. After inserting the roll and closing the lid they are installed in the turntable by means of a torque spanner. The beating process can only be started with the cover closed. It cannot be opened until the mill stops. The beating time is controlled by an electronic timer, the actual speed and the accumulated revolutions are digitally displayed.
