BP1620, BP1628 & BP1640 Granulators Page 30 BP1600 1. Verify that the alignment of the pulley s is correct. Utilizing a straightedge of sufficient length to span from one pulley to the other, place it along the sides of both pulley s. The entire edge of each pulley should fully contact the straightedge.
BP1620, BP1628 & BP1640 Granulators Page 31 BP1600 6. There will normally be a drop in belt tensi on during the first 24 to 48 hours of operation due to st retch and the belts seating themselves in the sheave grooves. 7. After this initial “RUN IN” period, the machine should be stopped and the belts should be re-checked for tension.
