Feige (1989) used the sensor-pin method for the measurement of peripheral and axial pressure distributions in a roller crusher. Schwarz and von Seebach (1990) discovered the "edge effect" in an industrial HPGR. Lubjuhn (1992) characterized the peripheral pressure distribution in a lab-scale HPGR using quartz and limestone.
