BELT TRACKING/TENSION
LOOKING AT THE TAKE-UP END OF THE MAGNET

TIGHTEN THE RIGHT TAKE-UP TIGHTEN THE LEFT TAKE-UP
Belt track and tension should be checked at least every three hours for the first two days of
operation. Once every three days after that.
If the separator is to be installed on an angle (inclined crossbelt) we recommend that the belt
be tracked with the magnet level, then suspend it at its intended position. The maximum
recommended angle of tilt for a crossbelt separator is 20 degrees on a standard design, 15
degrees on a severe duty (CR) design. If the belt is running off towards the lower side, tighten
the take-up on the high side or the side that the belt is traveling away from.
If the belt is still proving difficult to track, check the following:
 Are the bearings bolted down tightly to the frame?
 Have any moved or shifted?
 Are the top two idler pulleys and the drive pulley at right angles to the frame?
 Is the magnet self-cleaning frame twisted or bent in any way?
 Has the self-cleaning belt been stretched so that one side is longer than the
other?
 Have the ends of the belt been cut square to the edge of the belt prior to the
splice being installed?
