Electric external vibrators are generally used for loosening, feeding, consolidating and separating bulk solids and to reduce friction.
Loosening product accumulation and adhesion in hoppers.
Electric external vibrators produce non-directional, orbital oscillations.
To drive conveying troughs, sieves or vibration tables, external vibrators are synchronised to work in the opposite direction to each other in pairs in order to obtain a directional vibration.
The frequency and power of the vibrations can be matched to the particular process using an optional frequency converter.
Construction and operating principle: External electric vibrators are motors with unbalanced shaft ends.
The unbalanced wheels can be adjusted, thereby altering the moment, centrifugal force and stroke.
