Pneumatic ball vibrators of the NCB series are used wherever bulk materials need to be moved. They are ideal for emptying bunkers and for preventing bridging, rat-holing and build-ups. When driving chutes, sieves or vibrating tables, they ensure a continuous material flow. A key advantage is their simple construction.
The rotary vibration is generated by the high centrifugal force of a steel ball running on hardened, polished tracks.
Frequency, and therefore centrifugal force, can be continuously adjusted by regulating the operating pressure.
