Bulk Handling (Heavy & Mine Duty)

Product Description. PCI Heavy Duty and Mine Duty Series drum pulleys are used in numerous locations within a conveyor system such as head positions to drive a belt, or in return/tail, snub, bend and take-up orientations when belt tension and redirection is needed. PCI manufactures conveyor pulleys with quality and reliability at the forefront ...

Crowned pulleys are used in low tension areas

The exception to this is when the rated tension of the belt is 35 kilonewtons per meter (200 PIW) or less; then a crowned pulley may be used anywhere in the system. In lower tension areas of the belt, crowned-faced pulleys may have a slight influence on belt tracking. However, if there are serious problems with the belt such as belt cupping ...

Optimizing Conveyor Take-up Systems using Dynamic …

reduced to 55 kN. This is due to the fact that the return side belt tensions are increasing from the tail to head conveyor. Therefore the 55 kN tail tension would result in the same 85 kN T2 tension. Although a tail take-up is ideal for this type of conveyor geometry, in many underground systems this is not physically possible.
