The mobile crushers at YAMAMA CEMENT were fitted with two sets of 20 8V 4250 belts. Problems with the belt tension, and a lifespan of only six months at the most, made maintenance work necessary and resulted in production downtimes of 2-3 hours.
YAMAMA CEMENT converted the crushers to the maintenance-free optibelt RED POWER high performance belts. Since then production has been running without problems, even at high temperatures. Production output was increased, even though the number of belts required was able to be reduced from 20 to 18.
This led to belt drive cost savings of 5,114 US dollars per year.
