(b) Powered Roller Conveyor Introduction: In a powered roller also called Live Roller Conveyor, all or a few of conveyor, the rollers are driven by one or multiple motors through associated transmission system. The loads on the roller moved by the frictional force caused bet the loads conveyor are and the driven rollers supporting the load Powered roller conveyors are intensively used in heavy process plants like rolling mills to feed heavy and times hot metal to take delivery from the mill and to various other process at or equipment. The roller conveyors can be reversing type to suit the process or may be Non-reversing type which transport materials within the shop Parts of powered roller conveyors different from those of an o Rollers: The rollers of a powered conveyor is fundamentally unpowered conveyor in that the barrel and the shaft portion are integral so that they can be bear driven connecting to their shaft ends. The integral shafts are mounted on by power ings housed the frames at two sides. These are termed as driven rollers in The driven rollers generally subjected to considerable impact load (specially the reversing are type processing conveyors) and hence they are made stronger The rollers can be made from solid steel forgings castings or can be fabricated from or heavy section of tubes and solid shafts, machined all over for proper static and dynamic balancing. The varying between 400 to 600 mm for roller tables used in diameters can be heavy slab blooming mills, down to 250 to 350 mm for general duty transporting or conveyors Roller pitch is selected that the load is supported by at least two driven rollers. To so prevent sagging of the load between two driven rollers, non powered (idle) rollers may be introduced between two driven rollers.
