Natural-frequency spiral conveyor
with motor vibrator unit
Difficult-to-convey products such as rubber crumbs can be efficiently handled by special spiral conveyors designed as natural-frequency system that operates with a large vibration amplitude and a low vibration frequency. The spiral conveyors have two frequency-controlled motor vibrators and are operated without any driving elements like gearing, a slider crank, a coupling, or a belt drive.
Their main advantage compared to classic systems is the simplified design of the motor vibrator. Since they are operated near the natural frequency, they are also distinguished by a very low driving force in relation to the excited mass. A comparatively small motor vibrator size is therefore sufficient.
The spiral conveyor has a diameter of 1500 mm and a height of 6.5 m.
