Fig. 2 shows typical curves of one experiment with quartz stressed with a specific milling force of N/mm 2 at a roller speed of m/s. The stepshaped form of the curves is due to the reading frequency of the transient recorder adjusted to 1 kHz. With this fraction, only about six particles contact the sensor surface of 20 mm 2, therefore, the curves scatter statistically.

Do not run the mill dry. When product has almost run through, open the rolls and disengage the apron. Do not wear loose articles of clothing or any accessories that can get caught in the rolls. Roll journals are equipped with ball or roller bearings. It is good practice to lubricate the bearings on a monthly basis.
