Roller separating drums with individually adjustable separating gaps are ideal when only a limited range of parts needs to be separated or high throughput is required. The individual rollers are made of PVC, galvanized steel, or stainless steel and can be individually adjusted along the drum diameter. This makes this type of separating drum suitable for very small as well as larger and heavier components.

Furthermore, this roller separator offers the advantage that every gap between the rollers is a separating gap, thus enabling high throughput rates.

The throughput is almost twice as high as with a comparable roller separator drum with planetary central adjustment. A belt stretched around the drum cage and connected to the base ensures that all rollers rotate in opposite directions as soon as the cage turns. This significantly reduces the risk of parts jamming in the separating gaps. Due to the individual adjustment of the roller distances, the changeover process takes considerably longer compared to a roller separator drum with planetary central adjustment. Accordingly, this design makes particular sense when the range of parts is limited or changeovers are only required infrequently. This type of separator drum is therefore especially suitable for high-volume products. In some cases, it can be advantageous to interchange several pre-set separating drum cages to achieve faster changeover times. Depending on the specific requirements, these separating drums can be manufactured with separation lengths of 700 mm, but optionally also 500 mm, 1,000 mm, or 1,200 mm. To separate more than two different fractions, the inlet and/or outlet ring of the drum can also be equipped with, for example, holes or tubular inserts. Thus, combinations of hole/roller separating drums or sleeve/roller separating drums are possible. The roller separating drum type 357 B is an extremely robust and reliable aid in production for efficiently separating mass-produced parts – even under demanding conditions.
