The successful ERF series of vibrator units for trough and tube conveyors as well as screening and sorting machines was recently extended upward with the new ERF 62 type.
A maximum effective weight of 100 kg can now be handled at a vibration frequency of 20 to 30 Hz.
By comparison, the ERF 52 – the most powerful vibrator unit available until now – is only rated for a maximum effective weight of about 50 kg.
Especially when used as a multiple drive, this new unit is suitable for an exciting range of applications such as feeding packaging machines (multiple-head balances) over long conveying distances or batching and aligning fish fingers and confectionery, for instance.
The photograph below shows a 4.3 m long and 750 mm wide vibrating trough conveyor with three ERF 62 vibrator units and a pneumatically driven discharge flap for potato chips. The trough is part of a feed section with an overall length of 45 m and five 4 m long trough conveyors arranged perpendicular to the multiple-head balances.
