pulley is used for changing the direction of the belt running or
increasing the wrap angle between the conveyor belt and the driving
pulley. As per different carrying capacities, the bend pulley can be
divided into three categories: light duty, medium duty and heavy duty.
The shift of the diameter can be 50~100 mm,120~180 mm and 200~260 mm.
And the structure is the same with the driving pulley. The surface
treatment of the bend pulley can be smooth steel and flat rubber
bend pulley is usually installed at the tail part or the vertical
take-up equipment part when the belt direction need to 180°bending. It
will be installed above the take-up equipment part while 90°bending .The
pulley, which is used for extending the contact surface, is usually
used for below or equal to 45 degree bending.The drive unit has been
taken from the head pulley, and placed after the first bend pulley on
the conveyor return.
longer belts will have a greater expansion and retraction rate due to
climatic temperature changes. As temperature climbs the belt will get
longer. When it drops the belt will shrink. To compensate the conveyor
belt will have a pulley that is allowed to move with the belt as its
length is constantly changing. To keep proper tension on the conveyor
belt the pulley, which is called the take up pulley, is weighted. The
bend pulleys are called that because the belt bends over them to form a
loop for the take up pulley to sit in.
