Always try to use as few
balls as possible. Balls not
needed for a particular job
should be removed to
avoid wear of the belts.
It is recommended to use the following balls:
• for paper grades below 60 GSM: Plastic balls
• for paper grades from 60 to 150 GSM: Plastic balls, every fourth should be a
steel ball
• for paper grades above 150 GSM: Steel balls
In the infeed section (the first 4 to 6 balls), it is recommended to always use one or two
steel balls.
For very light paper grades, every second ball opening should be left free.
